SPECIAL SEISMIC CRISIS - 12/06/2011 (09:17 pm)

'Volcanoes of the Canary Islands' an initiative to actively contribute to the economic recovery of El Hierro

DIARIOELHIERRO.ES, writing (12.06.2011. 9:17 pm)
Volcanoes of the Canary Islands Association has recently launched the initiative 'Help The Hierro' in order to help restore the economy of the island's population affected by volcanic activity recorded since last October.

This initiative has two main objectives. On the one hand, provide the Association's digital platforms to disseminate all the interesting initiatives that seek to help the island of El Hierro. As a second goal is making a public call for new ideas among readers and participants of the websites of the Association, once selected, refer to the various administrations to assess their implementation.

Currently the Association has three information platforms: Forum Todogeología.com Tenerife (http://tenerife.todogeologia.com/viewforum.php?f=1) www.volcanesdecanarias.com Portal, and Facebook page Volcano Canary Islands (http://www.facebook.com/profile.php?id=100002182722640).

The first action was to create a special topic in the forum to centralize information regarding grants and measures already implemented to give readers easy access. Those interested can access it by clicking the link http://tenerife.todogeologia.com/viewtopic.php?f=1&t=1810.

To personalize this campaign a character for easy identification was created. This is Bimbachito whose image is free to use for those wishing to contribute to this cause.

From Earthquake-report.com Joke Volta:


VERY IMPORTANT UPDATE 07/12 – 14:48 UTC

Just in from Joke Volta looking at a news conference of Pevolca on TV

- Pevolca has decided to lift the crisis situation at La Restinga and to call a Yellow Alert for the entire island

- Pevolca has also decided to maintain the Red Alert to the Las Calmas Vent area !

- Pevolca has decided to allow boats to enter the La Restinga port again

- A maritime corridor of a 1/4 mile has been opened along the coast to allow navigating from La Esteca to La Restinga

- IEO and IGN have reported that the vent is 140 to 160 meter below sea level (Earthquake-Report.com : bathymetry was finished at the end of last week)

SPECIAL SEISMIC CRISIS - 12/07/2011 (15:39 pm)
EL HIERRO ISLAND REMAINS IN YELLOW SEMAPHORE

The Pevolca downgrades the alert level of volcanic risk in La Restinga to yellow

DIARIOELHIERRO.ES, writing (07.12.2011. 15:39 pm)
The Steering Committee of Civil Protection Plan for Volcanic Risk (Pevolca) has decided this afternoon to limit the red semaphore to the sea area where the eruption is occurring and which coincides with the maritime 4 miles exclusion zone. In this sense, La Restinga happens to be in the yellow semaphore, like the rest of the island of El Hierro.

Other measures also enabled with Harbourmaster agreed to a transit corridor for ships sailing from La Restinga to the north of 0.25 miles.

The Scientific Committee today reported Pevolca Steering Committee that there is a significant drop in the level of seismicity of the eruptive phenomenon since July has been occurring in the island of El Hierro, as reflected by the National Geographic Institute data for the last week where there were 28 events, of which only one, which reached a magnitude greater than 3 degrees, which was felt by the population. The location of the site remains largely in the sea of El Golfo at a depth between 15 and 25 kilometers.

As for the deformations and other areas of vertical motion, the Scientific Committee reported that they show a tendency to subsidence, although we must await the development of the phenomenon.

On the other hand, communications from many residents yesterday of a strong smell of sulfur derivative, it was found that the detectors and air quality stations provide normal parameters. In this sense, and although no parameters give any values ​​harmful to health, from the CSIC further analysis to examine the air components and continuous monitoring on the coast.

STABILIZED ERUPTION

From the point of view of the eruption, we can consider that it is stabilized and the seismic array continues to confirm that the tremor has a single source. For a week, and intermittently, fragments of lava have consistently appeared, whose analysis will provide new information on the evolution of the process.

In this sense, IGN confirmed that according to the research vessel Ramon Margalef the volcanic cone has unfolded and issued much material. There are currently three cones attached to each other and very close to each other, associated with the escarpment which the first cone rose from. This group reaches a depth of 160-180 meters.

They also indicate that the material is a course for 1700-2000 meters seafloor and no emissions on the northern slope.

The work of the ship Sarmiento de Gamboa note the estimated cone depth of 150 meters

The volcano El Hierro still to emerge. laopinion.es

Hierro volcano ejected lava down to 2,000 meter deep

Scientists ruled out an eruption out of the sea in present circumstances

CARMEN SANTANA
SANTA CRUZ DE TENERIFE
The submarine volcano eruptive phase of almost two months south of the island of El Hierro appears to be increasingly less likely to emerge. The direction of the Civil Protection Plan for Volcanic Risk (Pevolca), which manages the geological phenomenon, confirmed yesterday that the source material being ejected from the eruption is falling down on the two thousand meter deep seabed.

That, coupled with landslides on the volcano, confirmed by research vessels that have worked in the area in recent weeks, strengthens the argument that the aerial eruption would not be possible, at least in the current circumstances, as have maintained many of the experts from various agencies that followed the phenomenon.

The emergence of a new island as a result of volcanic activity off the coast of La Restinga was toyed with in the early days of the phenomenon that began last October 10.

But as the phase of underwater volcanic eruption has been evolving, with an increasingly pronounced decrease of seismic activity and stability of the tremor signal, has been reducing the chance of seeing any new emerging island south of El Hierro . Last November after a campaign in El Hierro, the studies of the research vessel of the Spanish Institute of Oceanography (IEO) Ramón Margalef confirmed the existence of landslides on the submarine volcanic structure generated by the accumulation of materials.

The map of the seabed off the island in that area and the location of volcanic vents, less than 200 meters deep, the emergence of a new island is now inconceivable with such landslides. At the same time, the National Geographic Institute Ramón Margalef confirmed to the Pevolca that it has found that the volcanic cone has developed and has been issuing a lot more material.

The result of this activity is that "at present there are three cones attached to each other and very close to each other, associated with the escarpment which the first cone rose from." And all these formations are new material, according to scientists, at a depth of between 160 and 180 meters.

From these three cones, then, the submarine volcano continues emanating lava and a large part of its flow is ongoing, not to the surface but down to depths between 1,700 and 2,000 meters. In addition, the Pevolca states that emissions are occurring on the northern slope of the volcano.

Scientists initially located the mouth of the volcano two kilometers from the coast and 500 meters deep,. The expulsion of smoking pyroclastics, which releases are becoming more widely spaced in time and with less intensity, the experts pointed that the volcano which has formed is less than two hundred meters from the surface. So it was estimated that the structure could have grown about three hundred and fifty meters before the occurrence of successive landslides.

Amzer Zo, have not all the fish around the island moved elsewhere?

[Hervé]

Amzer Zo, have not all the fish around the island moved elsewhere?

I don't think so... I still see seagulls around...

What happened was that the fishing got forbidden for the love of poisoning fear, etc... due to all the dead fish popping up (most due to shock waves as in explosions and the rest, mostly, as shown by the available studies, from lack of oxygen and very few from chemical poisoning) and all the fishermen and divers with their gears were moved out of La Restinga with the first evacuation.

Since the semaphore downgrade from red to yellow for La Restinga and nautical traffic reinstated between La Estaca and La Restinga along a 1/4 mile coastal corridor... boats are coming back.

The downgrade back to yellow semaphore being mainly due to the fact that most of the lava ejected goes down to sea bottom 2000 meters below instead of building up a submarine volcanic structure/cone.

As for the fish and sea creatures, they just need to keep upstream of the plume to maintain good health.

OPINION

The threat of misinformation
By David Cabrera de León (*)

"It is easier to live with more than 11,900 earthquakes than with some of the information furnished in the media."

I watch the news and read, quote: "The threat of the volcano. Since he set foot on the island, a strong smell of sulfur dominates the air and the dizziness is permanent ... "

I gather that the inhabitants of El Hierro, the same that walk every day on this beautiful island, which at any time since the beginning of the eruptive process that has gone on for four months, didn't noticed that we are short of breath or dizzy more than usual, except for occasional sinuous curve of the Summit; will agree that some information is making irreparable damage to the image of the island, the local economy and insular life,.

I know the work of all journalists is commendable and I know how important accurate information for crisis management is, which is why I want to step out and try to send a message back to sanity, a message about the true reality experienced by the Island and this Municipality, and the reality is that this type of "intros" is closer to fiction than to be merely informative, have painted such a very negative and unrealistic view of the current situation in the island that even some embassies recommend not to travel to El Hierro.

Those who live here, day to day, those who have come to visit, those who now know El Hierro, that of the 11,900 earthquakes, the underwater volcano, they know that it is the same as before the "crisis". Terrible word. Only more prepared now. We recognized that our country is volcanic, just like other parts of the world. We have learned to distinguish between earthquakes that occur on the coast from the ones which occur at sea, we have learned to organize, to develop security plans, and could continue with a long list of learning. No information has been hidden because being informed means being prepared. And we are more prepared than ever.

The traders, hoteliers, restaurateurs, farmers, carriers, they do. El Hierro is still the same, and its inhabitants as well, with the only difference that we do not know how long its economy can last if it continues to offer that image.

Proof that business is as usual is that the Meridian Island Marathon got 200 registered in the first two days of notice. They do have appreciated that the island remains the same, I hope the rest, officials, reporters and tourists understand and can appreciate, beyond spiced information for impact and the alarm of a true reflection of reality, that El Hierro is still the same, a different destination, with its peaceful difference and a new vision.

Webcams saga...

Today the RTVC.es camera operator folded early with his/her camera... it's Saturday after all... no visuals from that one...

As for the panoramic one from Telefonica/Movistar... well, it gave a panoramic view of the zoomed-on-Jacuzzi eruption one...

Here is the story starting from a few days ago when the Telefonica/Movistar guy was struggling to get the horizon on the eruption webcam... horizontal.

Here is that eruption webcam viewed through itself... well, at least its shadow on the ground next to an open truck-door:

As has been noted… there is a periodic noise signal in the CHIE spectrum/Helicorder plots.
Using my world view, and terminology, this is chugging. Yeah, it may have an official name. But with wagging, drum-beats, tornillo and what all for terminology… I call it chugging because that is what it seems like. It’s not the “poppers” term that I have used… which is also a construct and not official. Poppers are like really short tornillos. Every reference I have seen of Tornillos are that they are a lot of seconds to a minute or so in length. “Poppers” are less than 30 seconds or so and well defined. This … “bursts/chugs” are not well defined.

[...]

Either way.

This “chugging” could indicate that Bob is having a bit of difficulty in maintaining the vent/feed. As water rushes in and blocks the pipe, it gets vaporized and pushed back out. Rinse-repeat. Eventually it won’t be able to push it out and the “chugs” will slow. (if I’m correct) When it stops then the deeper system will either cool in place and go to sleep, or pressure will build. (cool, I’m right either way) What happens down deep… that’s anybodies guess. It may not like being unable to vent the pressure.

One thing is for certain… IGN should be in possession of or very soon to be in possession of, the most detailed picture of what it’s like down there. Here’s to hoping they don’t play the idiot politics game and just makes whatever call based on what the data actually says. Scr*w the wishful and career minded politicians. THEY don’t matter. Peoples lives do. If the politician doesn’t like it, tell them (who ever it may be) to take a nice long swim out at Bob’s Jacuzzi™. I’m sure the low pH water will heighten their awareness to the situation.

... which is very similar to what was expressed in post # 1304 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=346489&viewfull=1#post346489).

Current Volcanic Islands (AVCAN)

NOTE AVCAN 375 - EARTHQUAKE-VOLCANIC ACTIVITY - HIERRO ISLAND - DECEMBER 11 2011-11:30 h Iberian Peninsula - seismic-volcanic activity continues to moderate, with seismicity in the El Golfo marine area. Continues an important signal of volcanic tremor in the Restinga area, with an amplitude that remains slightly higher (a trend that carries on for 60 hours and where the intensity has doubled) and presents a growing number of explosions, possibly hydromagmatic every few minutes, a typical strombolian behavior for which establishes a balance between water inlet and outlet of gases in the exhaust duct so that it pulses like a geyser. The magnitude of the earthquake only 1.9. New earthquakes 1. 18km depth. Before yesterday 2. Yesterday 0. Today is 1. A total of 11,923 earthquakes are located in El Hierro by IGN from 9:00 am of July 19, 2011 (Enrique).

Only one earthquake today, a M 1.9 at 02:11. Yesterday... none!

Which prompted this reaction and response at Earthquake-report.com:



Update 11/12 -18:24 UTC
Yesterday we wrote in our 22:04 update : “Some think the eruption would stop if the earthquakes are halted“.

Dr. Boris Behncke from the INGV-Osservatorio Etneo, Catania commented on this statement as follows :

As a matter of fact, most eruptions are preceded by earthquakes, but in most cases the earthquakes stop once the eruption has reached a stable regime. The stopping of earthquakes does not mean that the eruption will stop anytime soon, the eruption might continue for years after the end of significant earthquake activity. Earthquakes are indicative of breaking rocks, caused by magma pushing into areas where there is no established conduit.

Once a stable magma flow occurs through a well-established conduit, there will be no longer any earthquakes.

The cessation of earthquakes only means that the situation has somehow stabilized, not that magma is ceasing to flow.

The real indicator of continued magma flow is volcanic tremor.

Only once the volcanic tremor disappears, then one might reasonably argue that the eruption is over.

... and the volcanic tremor has sure been busy, yesterday, playing the Tchoo-tchoo train tune!

Where the complications are coming from...

here is from a blogpost (http://rastreadorcanario.blogspot.com/2011/12/mil-y-una-razones-para-la-creacion-del.html), translated as best as I could:


Sunday December 11, 2011

THOUSAND AND ONE REASON FOR THE ESTABLISHMENT OF THE CANARY ISLANDS INSTITUTE OF VOLCANOLOGY

We are living a seismic-volcanic crisis on the island of Hierro from a few months ago, which was manifested by an underwater volcanic eruption which today is at its peak, with various materials and erupting mouths slowly growing and who knows if in a few days will come to the surface and amaze us even more than it has done so far.

Parallel to this situation, generated by a natural phenomenon, has developed a situation of serious economic crisis on par with the rest of the world that has become more evident and distressing on the island of Hierro, especially for the inhabitants of La Restinga, harbor which faces the Sea of ​​Calm, which for now houses an underwater volcano in its midst.

Against this backdrop of complexity and uncertainty, in which many Canarian citizens are awaiting the evolution steps of the phenomenon suffering from the ravages of the generated crisis, the Canary Islands Government, responsible for managing it through the application of PEVOLCA , originally assumed to be led by IGN in its scientific direction, an agency dependent on the Ministry of Public Development which by Royal Decree 1476/2004, the Council of Ministers in its Article 13 dictates:

"Director General of the National Geographic Institute.

... 1. The General Directorate of National Geographic Institute performs the following functions:

c. The observation, identification and reporting of earthquakes which occurred in national territory and adjacent areas, as well as study and research on seismicity and seismic coordination of regulations. Similarly, observation, monitoring and reporting of volcanic activity in the country and determine the associated risks.

... 2. The General Directorate of National Geographic Institute is composed of the following organs in general sub range:

b. The General Directorate of Astronomy, Geodesy and Geophysics, which corresponds to the exercise of the functions described in paragraph 1.a., through the National Astronomical Observatory, 1b, through Geodetic Survey Center, 1.c, through the National Seismic Network ...


ADDITIONAL PROVISION # FIVE: No increase in public expenditure.

The application of this Royal Decree, including the creation and modification of units without organizational level of general subdirectorate under its provisions, shall be no increase in cost of operating cost of the respective boards and will not increase spending. "

In this framework of legal blurriness, because of how complex and wide is the mission of the study of volcanic phenomena and the risk associated with it, and that purpose expressed so vaguely but explicitly stating that investing is not for development (resulting from the reading of the DA fifth), our society, especially the Canary Islands, neither could nor should remain unmoved by the relevance of this topic.

Therefore, with time progressing, in its plenary session on November 2, 2005, by unanimous consent of all its members, the Senate passed a motion urging the National Government to the creation of the Instituto Volcanológico de Canarias.

This agreement was applauded by all, throughout Spain, Canary Islands and out of them. Soon after, in January 2006, Parliament passed the Canaries non-legislative proposal that read literally "to take the necessary measures so that urgent and pressing, to proceed to the creation of the Instituto Volcanológico de Canarias (IVC) , funded mainly by the State Administration and the Canary Islands, with the support of the Island Councils "as well as detailing its main functions.

After nearly two years of the Senate's unanimous agreement that had aroused so many hopes, Senator and President of the Cabildo of Tenerife, again requested in the Senate, Instituto Volcanológico de Canarias to be constituted urgently.

The Minister of Education and Science on duty was limited in its response to praise the various initiatives that the Government had undertaken to improve research on volcanology, not responding at all to the specific question that he had done and why Canarian descent was (sometimes splinter no worse than the wood itself).

Today, almost seven years after this first initiative, which is certainly more than justified by what happened today:


- When we have an underwater volcano in full activity,


- When you are not completely clear on the possible evolution of the phenomenon from now on,


- When you know the potential and future eruptive scenarios that can occur in our islands,


- When monitoring volcanic gases are certainly the engine of the eruptions and the best precursors of these should be enhanced and improved by the obvious advantages that this may result in the prevention and risk assessment,


- When the monitoring of volcanic systems of our country is practically in diapers, especially if you look at the scientific methods and means that they use in other countries supposedly not as advanced as ours, but more aware of their risks and the need to assume them and study them,


- When the teams dedicated to these tasks gas monitoring, seismicity, gravity, deformation, temperature, pressure, etc ... are not even approved for all institutions who install them to do their jobs, or are approved methods of measurement, what the data obtained do not have the same value, scale and meaning in the absence of coordination of media and scientific strategies to carry out such measurements,


- When there is a reference center that brings together all the scientists, agencies and public and private institutions with an interest in the study, prevention and management of volcanic risk in the Canaries and hence in Spain ....


I can think of, many, many reasons to require that representatives of popular sovereignty, the members of government we have chosen to manage our tax dollars are put to work once and for all in creating the momentum unavoidable and the ultimate establishment of a VOLCANOLOGY INSTITUTE OF CANARY-based logic in our land, which is the unifying center of all efforts in the direction of the study of volcanism in our country, which becomes a reference not only at regional level or national, European or global also this important study, VITAL for the Canaries, because we are a land of volcanoes, we live on them and we can not continue to give back to this phenomenon.

What a beautiful name, INVOLCAN, suggestive to the utmost, as the text that represents INSTITUTE (place of teaching and learning, glue) VOLCANOLOGY (speaking of our natural essence) CANARY ISLANDS (especially in this land, because we are a land of volcanoes).

Above schoolyard quarrels, above political ideologies, lobbies over more or less established scientists, above all these impertinences that the safety of citizens, is to know our land better, our origin and destination, Science, in the broadest sense, is the research and the best development of our islands, we play a lot, if we do not face these challenges with intelligence and using the media and the opportunities that nature provides us, maybe not as unable to see from outside, awkward and even dangerous.

What vision will they have of us these thousands, millions of visitors who now observe with astonishment the disorganization and chaos that occurs informative about the phenomenon of the volcano of El Hierro?. Not to mention other aspects related to emergency management that are almost everyday in the media or politicians' mouth from any administration.

Plainly pathetic.

I hope this time is truly a turning point and involves a change in the forms and the achievements of those who do and do not wait.

Therefore, and as the culmination of this extensive personal plea, I will reproduce below the text a few years ago, my friend Nemesio wrote, scientist and volcanologist, director of the scientific division of the Tenerife ITER and today, driving force behind INVOLCAN, which spends many hours with his wonderful staff for the price to know for work purposes and I pay public tribute through this document to your immeasurable, though unknown, important work I hope to see fully rewarded someday.

"Instituto Volcánológico de Canarias
100 years of I & N (Ignorance + Neglect)

Nemesio Perez (*)

The volcanological Institute of the Canary Islands (IVC), one of the key pieces that you need to fill in society actions to reduce volcanic risk in this country, and should be called Canary Nacional instead, since this is the only volcanically active region of the Spanish territory, is still unrealized. This center has been calling for almost 100 years since Lucas Fernández-Navarro (1869-1930), then president of the Spanish Society of Natural History, called for the implementation and creation of this type of organism as a result of the eruption Chinyero volcano in November 1909. "The creation of an observatory at the Teide should be considered as a national debt of honor. Having a mountain of the height and nature of the Pico de Tenerife, in such a unique geographic location and not from it to use it to contribute to the advancement of meteorology, of volcanology and seismology, is simply a crime against science and a shame."

Since then there have been many attempts throughout the twentieth century to the present to rescue this initiative and encourage the creation and implementation, but has always encountered opposition from powers far removed from these islands and of general interest to that this initiative did not see the light.

Today marks two years since the Spanish Senate approved and unanimously agreed to request the State to create the IVC, following a motion by Senator Ricardo Melchior Tenerife. This unanimous decision, full of common sense and public responsibility, was subsequently supported by more than one hundred members of the national and international scientific community. This initiative of the Spanish Senate was added subsequently also unanimous declaration of the Parliament of the Canary Islands, following a non-legislative proposal submitted by the PSC-PSOE, to encourage the creation and design of the IVC which would be their functions. As a result of these two important institutional statements, the national and international scientific community gathered in Garachico last May 2006, during the 300th anniversary of the volcanic eruption that marked the development of this northern town in the eighteenth century, welcome again and encourage the Spanish government to implement the IVC as soon as possible.

In the history of the Canary Islands there has been no precedent for a scientific initiative so unanimously requested and supported from all fields, politicians, scientists and citizens urging the authorities of State and Government of the Canary Islands to be created volcanological Institute of the Canary Islands . Still not understood as the state administration has not collected the unanimous request of the Senate to initiate, in conjunction with other administrations, the work necessary to implement this Institute, which aims to reduce the risk volcanism and contribute to the safety of citizens.

Obviously, the Spanish citizens as a whole, is not aware of volcanic risk in Spain, otherwise, the IVC would have been around for a long time. Among the many reasons for this lack of sensitivity may be that this type of natural hazard affects only a small part of Spanish territory, far from the continent [Europe] and low weight in national politics. But there are other reasons such as:

(1) the fragile memory of the Canary Islands and Spanish society as a whole with respect to such natural phenomena, given the relatively low frequency of volcanic eruptions on the Canary Islands during the last 500 years;

(2) the mistake of the thinking and communication to society by some scientists and agencies, that the historical eruptions in the Canaries did not cause loss of human life,

(3) to think that the most likely scenario in the Canary Islands volcanic-basaltic eruptions low-explosivity index does not represent a significant risk to the population, since in the recent past (500 years) this type of natural phenomenon caused a significant number of human losses, forgetting that at present the population density, land use and civic citizenship behavior is very different from earlier times,

(4) belief and communication to society by some scientists and agencies that volcanic eruptions in the Canary Islands are quiet, forgetting that this term can not be applied to any adverse natural phenomenon however small its scale and impact that could potentially generate,

(5) the belief that future volcanic eruptions in the Canaries only be such as occurred during the last 500 years, forgetting that in the geologically recent past (last 10,000 years, equivalent to only 7% of the life of the volcano Teide, which is still active), there have been eruptions in the islands with the highest level of risk that occurred in the last five centuries.

Clearly today, to our rulers, the IVC is not essential to contribute to the safety of Canarian citizens to the volcanic phenomena, nor is key for leadership and scientific development of the Canary Islands in the field of volcanology, geology, seismology, etc.. and natural resources (water, mining, industrial rock, geothermal energy, environment, climate change, tourism generated by the unique volcanic, etc.). This reality is so obvious that the Administration claim urgent and urgent creation of the IVC, according to the unanimous decisions of the Spanish Senate and Parliament of the Canary Islands, should never be taken or construed as an argument in the service of political interests but is simply an exercise of public liability to claim your urgent creation because it is a debt of national honor and claimed 100 years ago Lucas Fernández-Navarro.

The IVC is still anchored in the inability and unwillingness of those who have an obligation to ensure the safety of persons for reasons inexplicable to us perhaps, but ultimately they are very closely related to ignorance and carelessness. The harsh reality, so present and continually repeated throughout our history, is that "you have to roar to remind Santa Barbara," which, referred to the Volcanology Institute of the Canary Islands, means we have to wait for the next volcanic eruption or earthquake crisis . Many things will then be too late.

I am baffled!

Yesterday, while considering the number of thanks my posts received lately, I checked the number of viewings... it barely made it past 67,000...

Today, while Polly is inching toward her 12,000 logged EQ at the rate of one shake a day... guess what?



***


Since July, IGN has officially logged 11,933 tremors at El Hierro... and still counting although seismic activity is considerably reduced!

Meanwhile, this thread just went by 70,000 viewings....


Thank you for your support and for dropping by! :wave:

SPECIAL SEISMIC CRISIS - 12/12/2011 (16:24 pm)

According to the latest INVOLCAN DATA, CO2 emissions continue to decline.

DIARIOELHIERRO.ES, redacción (12/12/2011. 16:24 horas)
The Volcanological Institute of the Canaries (INVOLCAN) confirmed to the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) that, as of yesterday, the volcano island of El Hierro is continuing a downward trend of the diffuse subaerial emissions of carbon dioxide (CO2) into the atmosphere reaching the 978 + / - 35 tonnes per day. The last measurement made by INVOLCAN, on December 5, establishing emissions of 1560 + / - 59 tonnes per day.


In terms of seismicity, the National Geographic Institute data recorded only one earthquake during yesterday, Sunday, which reached a magnitude of 1.9 and occurred at 18 km depth, at 02:11 hours northwest of Frontera .

The tremor recorded pulses of variable intensity and quasi-periodic, with amplitude slightly higher than the previous day and whose average intensity over the last 24 hours, shows a slight increase.

According to IGN, the deformation monitoring stations maintained the same pattern of recent days, following the same trend of stability in the vertical component and in the horizontal components.

A fairly large green spot continues being appraised, with a marked, brown head which has spread landward reaching the coast.

SPECIAL SEISMIC CRISIS - 12/12/2011 (21:07 pm)

Growing interest in the volcano.


DIARIOELHIERRO.ES, writing (12.12.2011. 21:07 pm)
The Tourist Board of the City Council of El Hierro has received numerous requests for information about the eruptive phenomenon present in of the Sea of ​​Calm waters and calls the attention of this type of tourism on the island.

The requests come from all over the world by groups like scientists, student groups and tourists interested in observing this unique phenomenon.

According to the Minister of Tourism of the City Council of El Hierro, Veronica Montero, who told DAILY EL HIERRO the current decline of the traffic light for the population risk (yellow on the island), "fosters a perfect time to raise awareness of the phenomenon to tourism, due to currently existing security level around the island territory and the normality of the phenomenon," she said.

Montero reported that El Hierro institution currently is working with the Government of the Canary Islands on the completion of three lookouts stationed in places of geological interest, promptly located in areas of volcanic eruption that had interpretive tables, a project included in the campaign "Canary volcanic experience."

In this regard, the Minister of Tourism indicated that there are several proposed initiatives from her department to promote tourism on the island following the volcanic phenomenon, but warned that these initiatives, "must be undertaken at the right time to avoid creating an adverse effect in terms of eruptive phenomena."

This gives a better idea of where the magmatic melts, fluids and gases have been naturally "fracking" the surrounding rocks and of the more accurate geometry of the magmatic emplacement.

The light is located at the same place as where the jacuzzi is: http://twitpic.com/7sykbq (http://twitpic.com/7sykbq) Just seen this 23.53 GMT/UTC on the webcan of Movistar. Could this be the eruption or a boat?! See it at second 00:10 (http://www.youtube.com/watch?v=zV5wGToiVZ0&feature=player_embedded#)


Very Important Update 14/12 – 06:40 UTC
Julio was not resting before he was certain that the light he recorded wasn’t traced back to the exact location. He superposed two images and scaled them so it would coincide with the port location and position. The effect is amazing. The flashlight really came from the vent and because of the distance it must have been a couple of meters high. Of course it can still be a boat, but we do not believe in that scenario as Julio looked at the other recordings later and NO boat was seen in the area. Julio will check his recordings during the morning hours to find out if new similar events might have occurred. The light must have been meters high based on the distance from the webcam (the webcam was not zoomed at the time)

VOLCANOLOGY INSTITUTE OF CANARIES


You will shortly see the light of volcanology Institute initiative de Canarias (INVOLCAN) and the Cabildo Insular de El Hierro with co-sponsorship of Civic Banking CajaCanarias in order to provide a bit more on the task of helping the community Herreño in these difficult times.

This is a 29x29cm calendar with some snapshots of the underwater eruption south of La Restinga selflessly ceded by members of INVOLCAN and the Helicopter Unit of the Guardia Civil in the Canaries. With a circulation of 10,000 copies and a price of 10 euros / unit, 50% of the profits will go entirely to the community El Hierro, while the other 50% will go to the implementation of educational and training programs on volcanic phenomena and management of volcanic risk in the Canaries.

If you want to collaborate and buy the calendar you can write an email to calendarioelhierro2012@gmail.com.

The price does not include shipping.

Thank you for all your effort on this thread. The Canary Islands were featured on Discovery Channel some years ago on the topic of tsunamis.

There is another thread on PA which makes a prediction for 2012 about the Islands. A little off topic, but PM me if you prefer and I will edit it off this thread.

Check La Restinga webcam (http://www.hierroendirecto.movistar.es/) eruption zone NOW... burning lava floats!

[Hervé]

Last night I started to compose a post about the above occurrence when my internet connection went on vacation... what I was going to post was this:

Unless someone's got the means to launch floating Chinese lanterns and flares on top of a live volcano, this is the best feux-follets display I ever got to witness.

It started with this, a faint glow on the panoramic view of La Restinga on the spot where the Jacuzzi was all day:

Followed by those from the eruption, zoomed webcam, where I thought it must be a ship decked with blinking christmas decorations since the lights were multicolored and flashing:

My trouble with this being a ship is that the lights disappeared one by one (see post # 1767 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=375271&viewfull=1#post375271), last picture), that doesn't happen with vessels of that estimated size.

So, for me the debate (see Earthquake-report.com (http://earthquake-report.com/2011/09/25/el-hierro-canary-islands-spain-volcanic-risk-alert-increased-to-yellow/)) remains between floating Chinese lanterns hoax and genuine, large floating lava boulders which fire and flaring is maintained by the flammable degassing... high temperature feux-follets as with blow-torches!

Here is a link to a video which recorded a portion of the show:

Again, notice what comes to light when flaring occurs.



On checking on the marine traffic and similar sites, there was no vessels cruising in the area at the time. The closest one was C Whale (see prior page). The possibility remains that a ship could have come from the GPS/AIS dead zone.

From Wikipedia:A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

About those night lights... I finally got some facts straight.

At the time of this screen shot:


https://public.bay.livefilestore.com/y1pSfY-6OwyZQDI_PrAE4kZJf9xKfTYvj9u1J-pzVRYjEoYngDqW99u9PRSA59L5JPaf6PqQoQeS3646pRnwxFUMg/Image_00242.jpg?psid=1




C Whale was about here (mid afternoon in El Hierro, time on screenshot is EST= GMT - 5 hours, EST + 5 hours = GMT = local time El Hierro):



https://public.bay.livefilestore.com/y1p706RLy-OaTgncAyl08SdMSCENUNDpF9ZaRrXv1MWnfafBzkeLi79bKqkPS-F8Aa1kufedRwmv-8HxDQ0qMbd1g/Image-2011-12-15-16h0mn36.jpg?psid=1




That's roughly 30 kilometers (17 nautical miles) from that restricted yellow area center. However, that was mid-afternoon when that tanker-turned-freighter was going out of the field of view of every webcam.


Last position before entering the GPS/AIS dead zone at a speed of 10.9 knots on a 272 course:



https://public.bay.livefilestore.com/y1ptcgb6cz2MGijhSbQuKHB6jsfa3YCzt0VZW7uoBEoEEb_A2nglzVfxHPZB9B10SYx0Dljji50dz1U73e1tewjGw/Image-2011-12-16-0h6mn39.jpg?psid=1




Now, at the time of posting the top post of this page when the lights were starting to fade, that ship was interpolated to be here (if not, then it's further west on that 273 course at 10 knots):



https://public.bay.livefilestore.com/y1pQt6Q7Uas_12bUf4EtgdqcXsJvh5Sz7s26hvu0BiNqFHlq-Nk4XwbhVAvXrPzKGb_TMIVK0Wdovzx8ICsEGQJew/Image-2011-12-15-23h32mn21.jpg?psid=1




... that's another 15 kilometers further away (25 nautical miles total) and that 340 meters long ship was already a mirage reflection at 30 kilometers... then, night, and 45 kilometers away with a poor webcam definition that doesn't even have as strong a zoom as the Ustream, mirage one.


The following position would be when Joke Volta saw the ship lights with binoculars around 7 am, local time, from the height of El Pinar:



https://public.bay.livefilestore.com/y1pAyfVWNEi6PJXtd9q-Z_gK94MpLUpEd9uGXS4Qh0zFv72MWEXgZJgteUdJfg4ncG3B1TGnty5GoRyKg51CPDLPQ/Image-2011-12-15-16h6mn40.jpg?psid=1



Now, that's about 60 kilometers (32 nautical miles) away by then...


All that to say that, that statement of IGN to PEVOLCA:




DIARIOELHIERRO.ES, redacción (15/12/2011. 15:15 horas)




The National Geographic Institute (IGN) has confirmed on Thursday to the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) that the lights that appeared yesterday in the Sea of ​​Calm (which were mistaken for the eruption of incandescent material) were a boat anchored from early afternoon about 17 miles from the coast and to the SW area of the eruption.


... doesn't hold much water either... since 10-11 knots are hardly indicative of an anchored vessel.

Also, see picture #4 in post # 1802 above where the faint lights can be seen right smack where the jacuzzi holds the spot... not SW of it.

... and you may get the idea that, in this thread we are relying on data to draw a rational picture.

As I once answered/commented to Bill:



-------

Dr Bill Deagle interviewed John Moore on his Nutrimedical Report radio show (30 Sept, hour 3). (http://www.gcnlive.com/programs/nutrimedical/archives.php)

John Moore reported that he'd heard from a private source that El Hierro would "cut loose" (i.e. there would be a major eruption or earthquake) in 7-10 days -- "not weeks or months". According to his source, that would of course be round about now.

Potentially important 1 minute extract: http://projectavalon.net/John_Moore_Bill_Deagle_Canary_Islands_30_September_2011.mp3

Hi Bill, interesting that an "insider" could predict a time for an eruption...

Hence the caveat:



[...]
...

Both Stan Deyo and John Moore have vested interests in catastrophic speculations as they both sell preparedness plans and items and are consultants for hire on disaster prevention...

Me think it's time to revise the origins and perpetuation of these speculated "catastrophes."

That said, a few well placed "explosive charges" could very well make me, and other experts, wrong... and it wouldn't surprise too many people as it is now a highly anticipated outcome due to the drummed up propaganda.

... how, indeed, can an insider predict an eruption or an earthquake -- when no genuily knowledgeable expert would dare to do so; "Ask the volcano" one wisely answered -- unless that eruption or earthquake were to be MANufactured?

Henceforth: :focus:

SPECIAL SEISMIC CRISIS - 16/12/2011 (13:50 pm)

IGN is not aware of the emergence of new magmatic material in the Sea of ​​Calms.

DIARIOELHIERRO.ES, writing (12.16.2011. 13:50 pm)
Scientists at the National Geographic Institute (IGN) have no record of new magmatic material to have appeared at the surface of the Sea Calms. What we have seen has been a pulse of tremor associated with submarine eruption of El Hierro, extremely long, which yesterday marked a change in its evolution, according to the Pevolca.

Thus, starting at 13:02 pm yesterday a reduced frequency and amplitude of the pulses which decreased significantly on the 18:20 hours, as recorded by scientists.

The oscillation of these pulses is considered normal in the evolution of the eruptive phenomenon and visible on the surface of the sea. As the stain clearly shows a dark brown head, fairly bubbling in the middle and a green area, which confirms the presence of gases.

As for ground deformation, the GPS monitoring stations recorded the same pattern of recent days, following the trends of stability in both vertical and horizontal components.

SPECIAL SEISMIC CRISIS - 12/17/2011 (18:45 pm)

The tremor signal maintained a constant level.

DIARIOELHIERRO.ES, writing (17.12.2011. 18:45 pm)
Yesterday, November 16th, the tremor signal held at levels similar to those of the last hours of the previous day. In this respect, the amplitude remained constant with two insignificant declines. The most significant record occurred at 21:26 hours when there was a high amplitude pulse that lasted 4 minutes and then returned to previous levels.

The evolution of tremor indicates that the eruption is ongoing and at present is not associated with seismic events. During the 16th, there were no recorded earthquake in the island of El Hierro but the provisional registration of the National Geographic Institute recorded at 2:40 am today, November 17th, a 2.3 magnitude earthquake, NW of Frontera at a depth of 22 kilometers.

In the stain visible on the surface of the La Calmas Sea, no dark tones nor bubbling were detected yesterday given the heavy swell state of the sea.

According to data provided by the Maritime Rescue aircraft Sasemar 103, after a reconnaissance flight in the focal zone, there was no difference in temperature from the sea background nor emission of volcanic material or surface water vapor.

I must say that Darla's post is where I am on this, particularly where she says to remain open to how you CAN leave the island. Not today or tomorrow but in a matter of months. Also you have a child to consider. Think too that once the crisis is passed (18 months abt?) you can return, perhaps.

I am feeling that the time frame here is 5 (or 6) - 9 months and the danger level is 75% that a strong event could occur ie submerging the island(s) and that the 18-month mark will see the story played out.

As to how we can also help here to release the pressure on more than one location along this zone, a group meditation as suggested is also a good one. I'm in.

Sory if that's not all warm and fuzzy but this timeframe carries challenges. While calmness is key along with holding the positive view, discernment is very important imo. We must all be ready to move at a moment's notice which means that we should release our stuff and carry very little baggage day to day.


I haven't heard any more about a possible move by Randles but I do remember that when I got this 5-9 month timeframe, I also got to watch Puerto Rico as a marker. Dutchsinse has just posted this about a swarm of tremors in that area. Just an FYi to keep an eye on.

An overview of the Restingolitas saga from:
Jose Luis Barrera Morate

http://blogs.elcorreogallego.es/elhierro/files/2011/11/banner.jpg
Geologist, specializing in volcanology. Author of 54 geological maps at 1:25.000 National Geological Map of the Canary Islands, among which are those of the island of El Hierro

Crisis volcánica de El Hierro (http://blogs.elcorreogallego.es/elhierro/)

The Canary Islands "float" packets of various sedimentary rocks
December 15, 2011 by Jose Luis Barrera Morate

The oceanic volcanism arising near the continental margins, is affected by the sedimentary deposits of these banks. The Canary Islands are no exception. On the island of Fuerteventura, one of the oldest in the archipelago are oceanic bottom sediments of Cretaceous age outcropping at the surface today. What is remarkable is that levels of marl and limestone are interbedded with submarine dark volcanic materials at the birth of the island. These materials were deposited from turbidity currents that transported limestone and terrigenous materials at the edge zone ("fringe fan") of a submarine fan, deep in the African continental margin.

While volcanism was developing in the archipelago, there have been many occasions when the rising magma has interacted with the seafloor sedimentary deposits of different ages. The precedents of this interaction are common in several of the Canary Islands. The last occurred in the eruption of Teneguía, La Palma, in 1971. Fragments were white and very porous, looking like foam, which were considered as rhyolitic igneous rocks, in a first interpretation made in 1973. Today, in light of what happened with the submarine eruption of La Restinga, they are reinterpreted as recrystallized sediments.

In La Restinga, the magma passed through some massive sandstones sediments debris (from the Sahara?), they recrystallized, lost water and became a white foamy rock texture. Early interpretations made ​​were deemed igneous, saying they were rhyolites and that authorities were minimizing the explosive nature of the eruption by saying that the rising magma was basanite and less explosive. These hasty statements with an exhibitionist tinge, violate the basic principle of precaution that must prevail in all steps of a crisis, creating confusion among the authorities and a social alarm that management does nothing to help. The geologist Jose Luis Gonzalez, crisis management expert, frequently says in his excellent blog about Natural Hazards page of the Association of Geologists, http://www.icog.es/_portal/inicio/inicio.asp, and other publications.

The first scientist to put sanity to this and showing that the alarm was unfounded, Tenerife geologist Juan Jesus Coello (http://www.avcan.org/?m=Noticias&a=noticia&N=911), who denied the rock's primary igneous character in his November 9 report illustrated with very educational colored drawings. Recently, new analytical data from several European universities have confirmed the sedimentary nature of the "Restingolitas" and finally settled the controversy.


http://blogs.elcorreogallego.es/elhierro/files/2011/12/Henry-seamount1-300x178.jpg (http://blogs.elcorreogallego.es/elhierro/files/2011/12/Henry-seamount1.jpg)

Had a bit of research been done, they would have realized that, at the Henry Seamount, about 35 km SE of the island of El Hierro submarine rift, German geologists described in 2005 that oceanic bottom sediment contents are getting to the seamount from El Hierro (see image). It is therefore predictable that the ascending magma in these places incorporated sedimentary material and recrystallized it, as seen in the pyroclastics that first emerged in the Las Calmas Sea. No other floating, smoldering pyroclastic expulsions after the famous "Restingolitas" exhibited the same characteristics.

Hopefully in the future greater caution will be applied in formulating claims instead of being hasty, lacking rigor and not contributing to good crisis management.


***************************
His "recrystallization" is not quite accurate since the restingolitas are made of glass foams... and glass is "amorphous," i.e. without a crystalline structure...

I find this statements interesting:


These hasty statements with an exhibitionist tinge, violate the basic principle of precaution...

Considering the "Dog & Pony shows" going on in other threads... not even hardened scientists are immune or impervious to it... :wof: in the form of grants for scientists.

Sorry but I'm flumoxed. Why Operator? And when I read your July posting I see that you interpret a more likely area of slippage to be Canary Is. Isn't that what I was alluding to - just watching the two areas' activity in terms of linkage? Actually, keep in mind it is not 'me' but info I got. Sorry if that is uncomfortable for you, not meaning to be.

Hi aquamarine!

Welcome to Avalon and thanks for the thoughts!

[Hervé]

Actualidad Volcánica de Canarias (AVCAN)

NOTE AVCAN 393 - EARTHQUAKE-VOLCANIC ACTIVITY- HIERRO ISLAND - DECEMBER 20 2011-10:30 h peninsular - seismic-volcanic activity continues moderate to low, without seismicity localized, but with some weak events detected. Continuation of an important volcanic tremor signal in the Restinga area, with an amplitude that is going down since midnight, by more than 20-30%, especially in the last hours at very low levels, with some explosions smaller than days ago, possibly hydromagmatic. No new earthquakes located. Before yesterday 3. Yesterday 0. Today there's 1. A total of 11,936 earthquakes were located in El Hierro by IGN from July 19, 2011, 9:00 am.

[Hervé]

Regarding the harmonic tremor signal and the different interpretations different authors attach to it, I'd like to remind Avalon's readers of one important thing; and that is the long sustained whistling Polly maintained after the initial break through:


https://public.bay.livefilestore.com/y1pjNySaTYeF9r7duSBTb-r8LkC75eZSoyhYCWDLIp8COYxUP2sd3U2UN7GBOIvQSQarGvK6Vx57mm_CdBtKogvTA/Panorama-02%201.jpg?psid=1

... that long, sustained whistling built a volcanic structure 150 meters high... magma outpoured freely and in high volume. The only diffence with the current situation might be that there is less degassing (green plume).

Sarmiento de Gamboa is back to Las Calmas Sea for yet another bathymetric survey which we all would like to see the results of...

Nothing -- not Mickey-Moused -- has been published since Ramon Margalef's first survey and, even that, was apparently done against hell and high waters from some authorities... seeming to indicate someone is getting political weights on being first name on first publication of the results and interpretation of said numerous surveys... to be followed.

Thank you for your diligence. There is now a complacency in the media. Earthquake Report is also stating a quieting - yet just days ago (not widely reported) gassing from 2 shallow quakes sent folk rushing to their homes in the western bay. What has happened to the non-disclosed venting near the tunnel? The news is stultified as per usual.
However, hopefully the venting and nastiness is really now abating....
Amzer Zo - you are our hero. Please keep tabs on those who really understand, and not just the localised/politicised groups. Thank you.

From Wikipedia:A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.



See top of page for the other auto-updating diagrams




The harmonic tremor is on-going and sustained which simply means the same for the under water volcanic eruption. This will hold true until the graphs display a flat line or the eruption becomes aerial. Not much else can be said or speculated about it.


The only question is whether or not the volcanic cone will surface before the graphs go flat?




Harmonic Tremor went flat line at around 10:30 this morning.

Harmonic tremor picking up again around 16:35

Notice from the Government of the Canary Islands


The most superficial zone of the volcanic cone in El Hierro has experienced a decline of about 15 to 20 meters


24/12/2011 ... 15:47 - Ministry of Economy, Finance and Security

This is a normal process of adjustments in the formation of volcanic cones that balance the volcanic structure.

The Sarmiento de Gamboa oceanographic ship captured a new acoustic image in the area of the eruption.

The Marine Technology Unit of the CSIC has informed the direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) that according to a batimetric survey by the Sarmiento de Gamboa research vessel, the shallowest of the volcanic cone on the island of El Hierro has experienced a small decrease of about 15 to 20 meters. This process, they say, is common in the formation of volcanic cones that undergo rapid growth and a series of adjustments that rebalance the volcanic structure.

In addition, the Marine Technology Unit of the CSIC has provided the direction of PEVOLCA an acoustic image obtained yesterday with one of the Sarmiento de Gamboa fishfinders showing what was happening at the time of image capture in the area the eruption.


https://public.bay.livefilestore.com/y1pb2Qw7k51f6FqwrsQ9w7ry9I6B5B30DPuzpCO3KoFIvsioqTcBH4eBxhI3ImzfakB5IqHIWB9gbCyM-NsaBzakw/Image-2011-12-27-22h28mn25.jpg?psid=1

In the image, comparable with ultrasound, the white profile corresponds to the relief and topography in the area of the volcano, while orange tones reflect the material being ejected from the volcano.

Also, in the time when the measurement was made, the emission from the volcano reached the surface. Some of the materials were suspended in the shallow zone correspond to the color brown stain as observed on the surface. For its part, the material in orange tones, it falls from the surface on the flanks of the volcano and the whole area of the eruption.

Tremor and seismicity
On the other hand, the National Geographic Institute (IGN) has confirmed yesterday to the direction of PEVOLCA that the tremor signal remained at the same values ​​of the previous days although presenting greater variability of long period during the day, no pulses.

As for earthquakes, it is noteworthy that in the day yesterday there were two earthquakes with a magnitude of 1.6 degrees, none of them felt by the population. The first, at 2:16 hours was found in the area of ​​the Gulf and 16 kilometers deep, while the second was recorded at 4:09 hours southwest of El Pinar at a depth of 15 kilometers.

In total, from July 19 11 934 events were located on the island of El Hierro.

Deformations
The control stations maintained a stable deformation pattern in the horizontal COMPONENTS and a tendency towards stability in the vertical one, throughout the island

As for the spot, on the morning of yesterday, a greenish stain extending to the south with no header could be distinguished. During the afternoon there was bubbling in the central area and stain issuer extending around to the southeast.

In addition, the report of the flight mission conducted by SASEMAR 103 yesterday afternoon, indicated the presence of a circular well-defined focus in the emission area without observing material or surface water vapor. The IR sensor detected an anomaly of 2.2 ° C in the emission area with respect to the background sea.

Now, my beef:


:rant:

Nice, colorful diagram and totally useless but for the bathymetry!

Why?

From what I can read on the zoomed picture, this is a composite of a zig-zag path projected on a plane, vertical cross-section.

No map, locating that path, provided.

Hence no way to pin where that particular cone is located or if it is even at the top of the cone or on its flank/side.

No horizontal scale.

No orientation for the cross-section.

Just a rushed, colorful job to calm down the voices rising in numbers and asking what happened to the data collected by Margalef and Sarmiento's first survey....

It seems that the rumors of Polly's return to her Sleeping Beauty deep slumber have been greatly exaggerated...

So, morale of the story... intensity of harmonic tremor has got nothing to do with submarine ejection of magmatic materials whether it be lava, fluids or gases in view of the above pictures of steaming lava floats and the size of the new plume of dissolved gases mixed with finer volcanic ash material.

5 hours later at Earthquake-report.com...



29/12 – 21:26 UTC




Besides the beautiful stain most of the day, Julio was amazed to find Smoking Lava Stones in his time lapse of the day. The smoking lava stones show up at 18:38 UTC while the harmonic tremor was slightly up. The video went too fast and finally the SLS could not be seen. He captured however a few images from that particular moment.

Smoldering fragments located in the emission area on Saturday

SPECIAL SEISMIC CRISIS - 31/12/2011 (16:35 pm)

The volcano again expelling large pyroclastic

DIARIOELHIERRO.ES, writing (31/12/2011. 16:35 pm)
The volcano of El Hierro continues to emit large steaming magmatic material, as they could check on the morning of Friday, scientists from the National Geographic Institute (IGN) from the Maritime Rescue boat Salvamar.

Since Thursday the emission was intensified in the header area where bubbling and fine material was observed. In addition, the green part was very definite throughout the day.

The report of the mission Sasemar 103, notes the observation of three very small emission areas and the corresponding material drift the south due to sea conditions and prevailing winds. Emission points in the water temperature was 17.5 ° C, while the nearest clean water temperature was 19.6 ° C.

TREMOR

During the day yesterday, Friday 30 December, the tremor signal recorded by the seismic monitoring network throughout the morning kept the same level reached the previous day.

However, slightly increased its amplitude at 09:30 hours, coinciding with the emission of lava fragments on the surface and an energy pulse was also observed throughout the day. This level was maintained for the day with slight fluctuations.

On Thursday, the tremor signal recorded by the seismic monitoring network maintained the level achieved the previous day, detecting some small pulses of short duration and slight fluctuations.

Although the signal tremor has a low amplitude, its presence in the record is confirming continuity of the eruption.

Moreover, in terms of seismic activity located in El Hierro, Thursday and Friday, IGN posted a total of 6 events of low magnitude, although none of them was felt by the population. On Friday three movements were detected at a depth of between 16 and 20 kilometers two of which were located in the area of ​​the Gulf, one at sea and one on land, the third also on land west of the town of El Pinar .

On Thursday, three events were recorded at a depth of between 14 and 16 miles, two of them located in the El Julan, of magnitudes 1.4 and 1.5, and another near La Restinga which reached 2.3 degrees of magnitude.

In total since July 19, 11 949 events have been detected.

DEFORMATION

Stations monitoring deformation showed a slight tendency towards the north in the horizontal components yesterday in the Gulf stations. For the rest of the island, the vertical components remained unchanged

[Rocky_Shorz]

after all the work you've done tracking this as the Island appears, we should name it after you...

Isle of Amzer Zo

[Hervé]

Thanks for the thought Rocky, and welcome back to the active member lot :)

Not sure such island will ever emerge, all I can gather is that since there is no indication of ground deflation it indicates that there is still a lot of magma in store...

[Rocky_Shorz]

has anyone done tests of what the breakdown is of the Lava gas emissions? It gives an indication of how long it will continue...

[Hervé]

Doesn't give much in terms of duration since it is still on-going... see this post (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=370536&viewfull=1#post370536)

The only reliable indication of things quieting down is that, currently, the ejected lava floats contain 35% crystallized material.

Thank you sooo much Amzer Zo, this has been a rollercoaster literally, Happy New Year, and although things were very exciting and frightening, hopefully there WILL be a little new island dedicated to you!!! Then hopefully that 'indigestion' in the area will calm down for many years to come....
All the best

As I am getting up-to-date on what has happened around El Hierro during my internet connection hiatus, I checked GeoLurking YouTube channel to see what's new and was taken aback to read: "... this video has been removed by the user."

WHAT!?

Found out there's been a p*ss*ng contest behind the scene with the head of INVOLCAN:



Nemesio M. Pérez

To:GeoLurking

Dear Sir,
The Takeshi Sagiya’s GPS data from El Hierro is not a public data and is related to a research project in progress. I would appreciate if you can delete the videos based on this information which it has been taking from Takeshi Sagiya web page without his permission. Thank you in advance for your collaboration.

That same NP of whom Juan Carlos Carracedo had this to say:


Tuesday, October 11, 2011 at 12:00 pm
http://comunidad.laopinion.es/media/entrevistaChat/carracedo.jpg
Juan Carlos Carracedo

Volcanologist Juan Carlos Carracedo answers on Tuesday at 12.00 hours to all queries from readers regarding the earthquakes in El Hierro and possible underwater preerupción south of La Restinga. Since mid July, the island has seen more than 9,000 earthquakes. The higher intensity took place last Saturday and had a magnitude of 4.4 on the Richter scale.

[...]

17. Doctor Carracedo. You think the IGN has conducted a volcano monitoring appropriate to this crisis? Or is there a need to create more resources and work together as Nemesio Perez claims?

"Nemesio Perez is a disaster for these islands and volcanology. The IGN is a serious institution that has handled the crisis with skill and scientific rigor. NP "directed" the "crisis" of 2004, which was much lower than this and had no effect, and nearly wrecking the economy of Tenerife. He is a politician, not a scientist, and his support base is the political friends, not his scientific career (rather poor). Not even dare to stand for opposition ... as we have all done.

Finally, some results and conservative interpretations...

Below, in three parts (due to maximum # of pictures allowed under one post) is my translation of a report concocted by Dr. Elena González Cárdenas on AVCan (http://www.avcan.org/?m=Noticias&a=noticia&N=913).

************************************************************

BATHYMETRY MADE IN EL HIERRO (Elena González Cárdenas) (http://www.avcan.org/?m=Noticias&a=noticia&N=913)
Dr. Elena González Cárdenas is Professor of Physical Geography and Dean of the Faculty of Arts at the University of Castilla-La Mancha. She is also director of research group "Geomorphology, Planning and Landscape in Volcanic Regions" as part of the Department of Geography and Regional Planning UCLM. Thanks to the research work of this group (GEOVOL), the Smithsonian Institute, under the Natural History Museum of the United States recognized the zone of "Campo de Calatrava" as active volcanic area.





BATHYMETRY MADE IN EL HIERRO
INTERPRETATION AND COMMENTS
Elena González Cárdenas


http://www.avcan.org/varios/Imagenes/egc00.jpg
Source:Spanish Instituteof Oceanography.IEO

In an eruption process of submarine character such as is occurring on the island of El Hierro, the bathymetric survey of the space in which the eruption is taking place is an essential tool to understand, first the situation and characteristics of the eruptive process and, subsequently, to determine the morphological and geostructural changes in the eruption area, growth and evolution of the volcanic edifice, its morphometry, and the relationship of these parameters with the volcanic hazard and risk to the coastal population centers in first instance,.

The bathymetric imaging are the basis for understanding and addressing the complexity of an eruptive process as it affects the Sea of ​​Calm and that surface observations can not and should not be used alone to draw conclusions and explanations for the specific situations that occur in the eruption, much less predict their evolution.

Bathymetric images are in these cases, an indispensable point of support that give a reference frame for the results of other parameters derived from a proper monitoring of volcanic facts (seismicity, deformation, gas emissions, etc).



Figure 1. Images of the ocean floor before the start of the eruption and after a few weeks from the start of it.


http://www.avcan.org/varios/Imagenes/egc01.jpg
Source: IEO Spanish Institute of Oceanography. Interpretation by an unknown author

In the first images obtained from the ocean floor, once the eruptive process has begun and when compared with previous ones in that process, can be seen a changing of the background to the creation of a volcanic edifice of conical structure in which the presence of a crater is distinguished. The IEO researcher, J. Acosta said that "had been located, in the waters of El Hierro, a volcanic structure with an almost perfect circular cone at the end of a fault zone." "The underwater volcano, a cone of about one hundred meters high, in a kind of vertical valley with a rise of fluid from the volcanic edifice that was detected, a significant gas column that reaches the surface and leads to a spot visible for days in the Sea of El Hierro."



Figure 2. Image of the ocean floor with the volcanic edifice housed at the head of a submarine canyon


http://www.avcan.org/varios/Imagenes/egc02.jpg
Source: IEO Spanish Institute of Oceanography.

In this bathymetry, the head of the submarine rift valley can be seen and the volcano that is forming inside. The appearance is of a kind spatter cone "hornito" with a pointed top that can be interpreted either as a leak almost cylindrical, very abrupt, or a horseshoe-looking open mouth, this second interpretation is more in line with the flowing lava that seems to be issuing from and running downhill. The slopes of the volcano can be seen very pronounced, as befits this type of construction.

Source: IEO Spanish Institute of Oceanography. Interpretation by an unknown author.


They begin to perceive interpretations of the images that do not seem very consistent with eruptive processes, and in any case, do not clarify the position of volcanic materials in the background. Figures A and B show a different arrangement in the materials that make up the cone and the "deposits" referred to by IEO technicians and there are also important differences in the morphology of the canyon. The canyon bottom inserts in Figure A, "disappear" in Figure B, to reappear in C, which sees the release of a large block whose dimensions are similar to those of the volcanic cone.



Figure 6. Bathymetry in which further changes can be seen on the ocean floor.



http://www.avcan.org/varios/Imagenes/egc06.jpg


Source: IEO Spanish Institute of Oceanography. Interpretation E. Gonzalez



In this picture, further changes are reflected on the ocean floor. You can see the unification of the two mouths of issuance of the previous bathymetry. Substantially modified the layout of volcanic landfills material reaching the bottom of the submarine canyon, clogging its head and overflowed to be placed on the upper platform. It also shows the existence of a tongue of lava material that seems out of an eruptive mouth at the head of a valley, secondary to the main valley. Here there is the large piece detached from the wall of the valley (see explanation in Figure 7).




Figure 7. bathymetry compared

1. Zone of accumulation of lava material with modification of the topography due to possible narrowing of the canyon lock or drag of the loose block (point 2) and subsequent coverage of such block by new lava input. 2. Block material covered by lava, or gone?. The drag of detached block seems unlikely because it would have clogged the narrow canyon acted as a dam, and generated a large accumulation of lava "upstream" of the obstruction. 3. Small canyon with an alleged accumulation of lava. There seems to be a substantial change in the topography of the small valley on the accumulation of lava. Was there really such accumulation?.



Figures 8, 1, 2, 3 and 4. Bathymetric images taken by various agencies and at different times.

Source: Images 1-2-3, IEO Spanish Institute of Oceanography, picture 4: National Research Council CSIC initial interpretation of unknown author. Interpretation of morphological changes and thermal anomalies in the photos 2-3-4: E. Gonzalez



Images from different dates and agencies can only approximate the reality of the existence of a possible emission mouth as discussed in the final bathymetry by the IEO. The circles indicate the possible zone of anomalies that coincide with the plume of secondary emissions indicated by the IEO (Figure 8.1).


The layout and characteristics of the probes and programs applied to image capture, distorts the profiles of each other. However, the comparison of the images seem to reveal, depending on the color tones on the right (NE) of the cone zone exhibits thermal anomalies that could correspond to the second leak, marked by the IEO (Figure 8.1)


It also seems clear that there has been a change in the volume and profile of the volcano, with a possible widening of the base and a decrease in eastern and western slopes. The new ejecta would have changed the surrounding reliefs, filling valleys and hillsides, linking with the walls of the head of the submarine canyon where we can see the volcano.


The latest report issued by the IEO, notes an increase in the slope of the volcano on the southern slope. This datum is not evident in the images published since they lack an orientation, but appears to coincide in Figure 8.1 with the space right where the huge IEO logo has been placed.

Figure 9. Bathymetric image in which the new volcano, the crater and possible eruptive fissure are indicated.


http://www.avcan.org/varios/Imagenes/egc09.jpg
Source: IEO Spanish Institute of Oceanography. Interpretation by an unknown author


Among the reports issued and images published, we must highlight the differences observed between the first and last performances (Figure 8. For example, this image indicates the existence of an "emission groove of fluid/ lava" or possible eruptive fissure, and there is a sort of curved crack which also seems to be emitting lava.

Keep in mind that all images are filtered, it has only become clear that there are three mouths of ejection: the two seen in Figure 5.B and the one indicated in Figure 8.1 as "plume emission".

However, assessments carried out from photographs taken by the Civil Guard helicopter and released by INVOLCAN, shows the presence of multiple emission mouths, with a clear WNW / ESE (Fig. 9). From these oblique and other vertical images, coordinates are derived from the emission points, and are located on the surface and the seafloor (Figures 11 and 12)

An alignment of possible eruptive mouths has also been observed along a NNE / SSW trend (Fig. 13 b) and from oblique and vertical aerial photographs (Figure 14). These alignments would correspond to a submarine eruptive fissure. However, without prior knowledge of the direction of surface currents on the day the photograph was obtained, it is as safe to categorically say that the case of the marks left by the activity of multiple mouths in a fissure may as well be corresponding to a displacement of material issued, dependent on the direction of prevailing winds.

In recent weeks, the eruption observed on published photographs, indicate a potential single point of concentrated emission, coincident with the crater detected by bathymetry (Figures 15 b). However, in photographs taken on 23 and 24 January, AVCAN partners (Figures 16 b), and scanned images from the Webcams installed by various institutions, seem to appear, at least three distinct sources of emission of gases and pyroclastics (Figures 14 b)

Amer Zo, if there are actually multiple emissions points from a fissure, what does this mean?! It can't be good. Will the ultimate outcome be a lot worse than previously reported?

It just means that instead of creating a big, single volcano, the process generates multiple small ones as in Hawaii:

See post # 1335 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=347585&viewfull=1#post347585)and post # 1375 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=349148&viewfull=1#post349148).

That's a GOOD thing since it spreads ejection of lava along considerable length instead of being focused out of one single point, especially in a submarine environment.

It also makes the outcome less dangerous than expected or claimed by fearmongers.

[Zaradia]

Thank you for the explanation. This is a huge relief. We certainly need to diminish the fear on this planet.

Summary of the day from Julio del Castillo Vivero with his time-lapsed video.

Of particular interest is the very beginning of the video where "burning" lava floats are seen, strikingly similar to the "C-Whale" videos... floating Chinese lanterns (see post # 1802 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=380894&viewfull=1#post380894)).

Now, this is very interesting: that in spite of a minimal to non-existent Harmonic Tremor (see graphs above), Polly is still spewing lava enough to generate smoking lava floats which in turns means that magma is still circulating... so, when I read of vent collapse etc... shutting down magma ejection... I am kind of doubtful.

In a long article published in El Mundo (http://www.elmundo.es/elmundo/2012/02/09/natura/1328782759.html) summarizing the views around whether or not the eruption south of La Restinga is going to last or is in its last moments; the only reliable datum provided is this one:


"We have reached the fourth month, which makes it historically the longest eruption in the Canary Islands with the exception of Lanzarote in 1730," says Marti, who argues that "symptoms" suggest that the process will be increasingly less, as noted by the composition of the magma.

In this regard, he notes that the degree of crystallinity of the rocks has changed quite a lot because, at first, when the magma was hotter, it was only about 5% of crystals, whereas now this composition is almost 50%, an indicator of apparently no deeper magma recharge.

Joan Martí adds that there are no scientific or technical means to calculate how much magma is left to get out and explains that the only thing you can do is continue the monitoring since access to the structure of an underwater volcano and its cone "is very difficult ".

The percentage of crystallized components in the lava floats was about 35% two months ago (see post # 1869 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=392334&viewfull=1#post392334)).

It just means that the original magma is cooling down and not being "re-heated/melted" through new injections of fresh hot magma and, therefore, should be entirely "frozen," i.e. crystallized, soon.

However, with this recent earthquake at a depth of 26 kilometers east of Tenerife, there seems to be some magma movements deep down there...

During the day, there was little to no activity beside the stain/plume spreading around, especially no noticeable jacuzzi manifestations while the Harmonic Tremor was strong.


Curiously, when the Harmonic Tremor tapered down in the evening, the jacuzzi activity began to be more and more noticeable...


The point being that there is no direct correlation between amplitude of Harmonic Tremor and jacuzzi activity or ejection of smoking lava floats.

Hi Randles, I am amazed that you are remaining so calm at the moment, it sounds terrifying. I have heard about the possibilities of what will happen if the volcano goes up, it was on a documentary here in the uk a couple of years ago. By the volume of earthquakes a day you are talking about, it sounds as if the volcano is waking up. When did all these quakes start happening? Like everyone else here on this forum, I wish you all the best but someting inside of me is saying if you can then start considering getting the hell out of there. Good luck and be safe.

SPECIAL SEISMIC CRISIS - 12/02/2012 (14:18 pm)


The EMU is removed from El Hierro


DIARIOELHIERRO.ES, writing (12.02.2012. 14:18 pm)
Stability in the underwater eruption that occurs in the waters south of El Hierro has caused the withdrawal of some of the dispositives placed on the island. So, this Sunday concludes the withdrawal of the Emergency Military Unit (UME), the Canarian government said in a statement.


Thus, the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) maintains some checkpoints, which also involved the Red Cross, to give a first response if there were a risk to the population. Come this case the means of the EMU would be back on the island immediately.


Meanwhile, the National Geographic Institute has confirmed to PEVOLCA that the tremor signal recorded by the seismic stations of the monitoring network IGN, remains generally constant with increases or decreases in amplitude throughout the day.


In terms of seismicity, IGN spotted 5 earthquakes yesterday in the area of the Julan and Sea of calms, with magnitudes between 0.9 and 1.7 on the Richter scale, in depths less than 16km.


None of these events was felt by the population. The previous day, Friday, 8 earthquakes were located in the same area at a depth between 8 and 13 kilometers.


Finally, the direction of the Plan maintains a surveillance of a phenomenon that is still developing in the Sea of ​​Calm and whose study has been agreed at the meeting of the State Committee for the Coordination of Volcanic Risk, on Friday, November 10, 'preparing a replacement program for the Ramon Margalef, Spanish Institute of Oceanography', allowing 'the provision of various ships of various branches of government, which will rotate and have different technological capabilities so that the scientific community can continue technical studies.'

My apologies Amer Zo, yes I am new to this forum and haven't had time to read every single response to this thread. I had no idea that had been debunked, all I know is that after Randles original posting, I did a quick search and found an article in one of our daily papers online sites, which backed up her story. I was merely commenting that the situation seems close to going critical. Does anyone know how high this undersea volcano is? Also if it does blow and the caldera collapses, won't that trigger a tsunami as the water rushes in? Forgive my lack of scientific knowledge on these matters. More curious is the fact that this story has not been on any of our television channels, I wonder why.

Hi Bramstome!

If you are truly intersted in the subject, I would suggest you take your time to peruse this thread since many of your questions have been addresed in some fashion therein.

As for the "why" this story hasn't appeared in your MSM is mostly because there wasn't enough fearmongering juice to milk out of it, except maybe for your "Dailymail." Another reason may be to maintain some vestige of tourism from your islands down to those Canaries.

Concerning the height of this submarine volcano, see below... fresh hot off the press.

The IEO has established the depth of the top of the main cone of the underwater eruption at 120 meters.

02/14/2012 ... 16:19 - Ministry of Economy, Finance and Security (http://www.gobcan.es/noticias/index.jsp?module=1&page=nota.htm&id=147395)

The eruption is still active as well as the magmatic reactivation process, therefore surveillance is maintained

The scientists responsible for the Spanish Oceanographic Institute, which oversees the ship Ramon Margalef, have confirmed to the direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) the depth at which the top of the main cone of the submarine eruption is estimated to be 120 meters.

The emergence of a secondary cone attached to the side of the main cone has also been found in the bathymetry done a week ago, it has a height of 75 meters and its summit is 200 meters from the surface. From the work done so far, it is also apparent that the emission of material varies around the main summit and that this area, east of the Julan, is the only place -- in all the surveyed areas in the various campaigns -- in which volcanic activity has been detected underwater

These have been the main conclusions presented at the meeting this morning of the scientific committee of PEVOLCA, held in Santa Cruz de Tenerife, which was attended by Director General of Security and Emergency, Juan Manuel Santana, the deputy Minister in the Canaries, Guillermo Diaz Guerra, the Director General of Civil Protection of Ministry of Interior, Juan Antonio Diaz Cruz, by videoconference, and representatives of scientific institutions advising the PEVOLCA: National Geographic Institute, Institute of Volcanic Islands and Centre for Scientific Research.

Regarding the evolution of the eruptive phenomena, the Scientific Committee has concluded that the eruption is still active and the process of reactivation continues on the basis of magmatic gas parameters, deformation and seismicity. Therefore monitoring remains constant in case there is significant variation.

For its part, the director general of Civil Defense announced the PEVOLCA address at the end of this week's meeting will be held to establish the rotation system of vessels for carrying out scientific work to follow the development of the process.

Finally, the Committee agreed to open access to the cove of Tacorón once a system of continuous measurement of gases is connected with the 1-1-2 CECOES room, and informative billboards are installed in the area.

From Wikipedia: A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

Juan Carlos Carracedo spills the beans:

Wednesday, February 15, 2012 00:21

http://www.elhierrobimbache.com/cache/multithumb_thumbs/b_196_147_16777215_0___images_stories_carracedo_y_freddy.jpg (http://www.elhierrobimbache.com/images/stories/carracedo%20y%20freddy.jpg)

El Hierro Bimbache.com has been in contact with some of the most prestigious volcanologists and, given the insistence of readers, this newspaper (http://www.elhierrobimbache.com/index.php?option=com_content&view=article&id=2431%3Acarracedoahora-lo-quieren-arreglar-politicamente-dando-parte-del-dinero-que-ellos-mismos-hicieron-perder-&catid=50%3Apersonajes-de-canarias&Itemid=50) has contacted Juan Carlos Carracedo.

1 - Juan Carlos are you still following the seismic activity in the island? And to what extent?.

Still occurs at a very low intensity of seismicity. It is also true that what it means is most likely nothing. Should know, can not be the case, which would have occurred before the eruption if it had disposed of the same network of seismic stations. In any case there is no evidence of reactivation, but decreased activity.


2 - An expert from the CSIC states that the emission center is running out.

The categorical assertions are not scientific. If all goes well it is likely that the eruption terminates. If you renew the cycle no one could predict now, but would be detected in advance by the seismographs of IGN and ground deformation.


3 -Expert also says it can take an average of fifteen days, being ten or twenty, but is in the final. Would you think?.

I do not believe in fortune tellers ..


4 - Expert Ortiz says that the eruption of El Hiero could end up in another mouth "in Lanzarote and Tenerife." Could such a scenario be?

This "expert" is the same who put Tenerife upside down with his prediction of an explosive eruption and the collapse of the northern island. He even also gave the date: May 9, 2004. As nothing like that happened, of course, [he ?] should shut up forever.

It is inconceivable that they have done it again, to help this unnecessary chaos in this eruption of El Hierro. This is the land we have.

Moreover, this expert devised a fantastic model that assumed that El Hierro was split into two halves and they were hooked. The "release," this visionary expected "any time" was the basis and foundation of The Roquillos tunnel closure and much of the fear instilled.


5 - The politicians sold the island and give us misery handout. In your experience should the institutions "sell" our volcano? .

Since so much money is being spent and cast on luxuries, why not make a useful trip and go to Hawaii. There you will see that in cases like these and much worse (an eruption under way for 29 years, earthquakes of up to 8 on the Richter scale, etc.), the population live without anxiety or economic catastrophes. To the contrary, they rake in billion from the volcano. Indeed, there is no stifling regulations as we have here.

You can go anywhere if it is public and all they tell you is that you use "common sense". Everything is marked and everything public belongs to the people, not politicians as here, we seem to have to be "authorized" to visit our farm. Of course, the most interested take advantage touristically, never used to scare people and drive away tourism.

Politically it has done enormous damage to the island based on a more imaginary than real danger, because the characteristics of the eruption never became dangerous. Now you want to straighten politically by giving part of the money they were losing. To see if it is true that they give it.

6 -A professor of Geology and Marine Sciences at the University of Las Palmas de Gran Canaria expressed that the volcano of El Hierro is being studied "deficitariamente" from a scientific point of view What do you think of this?.

That is absolutely right. After 40 years this eruption was handled infinitely worse than Teneguía. Excess politics and shortage of science.

7 - This professor said that while the cone of the volcano is more than one hundred meters deep, as now, will remain "safe" from the point of view of safety of the population. What do you think?.

Absolutely. The eruption can be likened to a bomb, but if it is going to explode 100 km away, it does not present any danger. There is a limit where we would be forced to evacuate ... In the case of this eruption that limit was never reached. Much of the blame lies with the ship that was sent with the mission of bathymetry to know the progress of the volcano and its rate of approach to the surface. They did so deficitariamente that it was the cause of the evacuations... totally unnecessary.


8 - Can you summarize what happened and what might happen, from a scientific viewpoint?

What happened is that there has been an eruption, normal thing in the youngest island of the archipelago, and underwater, also normal because El Hierro has 90% of its volume under water and there are evidently submarine eruptions that "air."

What happened also was that the scientific assessments were "distributed" among friends, without regard to anything they have worked on or know of the island and its volcanism. It is like hiring scouts from a group of people who have never seen an "Indian" or ever left New York in order to go West.

This time it was the very Government of the Canary Islands which has, ignoring local institutions, made it difficult (if not prevented, though they deny) for Canarian scientists and other national and international institutions that offered their services. Even when they came on their own to the island by pure scientific interest, and met with serious difficulties. The sampling necessary for real knowledge of the evolution of the eruption, was restricted completely, and we had to "contrive" to get them. By the way, thank you very much to residents of La Restinga for your kindness in offering us restingolitas pieces.

Thanks to those, we could get these samples and the true nature of these restingolitas has already been published . The work, through the collaboration of centers in Canada, Germany, France, Sweden, England, Italy, as well as Spain (mainly the University of Las Palmas) has already been published in a scientific journal of international class. However, although it was sent a copy, PEVOLCA ignored it, the only report listed as "official" on the Pevolca CSIC web page is completely wrong.

Science is universal and gates should never be put to the work of scientists to make a play yard in order to take advantage of the eruption for their own purposes (publishing the results and take a leading role) and avoid competition. Quite the contrary. I hope (but do not trust) they learned something.

Greetings to all islanders of the islands on which I worked for 20 years and have always enjoyed the friendliness of its people and its wonderful nature and thanks to El Hierro Bimbache and its director.
Juan Carlos Carracedo

Earthquake-report.com (http://earthquake-report.com/2011/09/25/el-hierro-canary-islands-spain-volcanic-risk-alert-increased-to-yellow/) reports this:



Update 17/02 – 00:38 UTC
- We have just seen burning lava balloons on the eruption webcam. Upper left part of the screen. they must be rather big as they burned for several seconds. Hopefully it will be repeated for people who start to look now.

- HT is still very low but as seen in earlier periods, a relation in between HT and SLS was never proved.

- ER reader Martyn was able to capture a few minutes on the webcam. He proves what we were talking about. As the webcam is zoomed out completely, the lights are very small but the flames must have been at least a meter or more on the spot itself.


Update : ER reader New wrote a comment below and is talking about a boat or even stars or planets. She may be right and we may be right.


It is up to everyone to make a guess about it, we respect every opinion.


ER is reporting whatever we see that can be linked to the eruption. The flashes have been noticed a number of times. The video below is only 1 episode. The main reasons why we are convinced that it is SLS was not said before : besides the time of appearing, the flames are also slightly floating to the right, different incandescent colors and the position of the vent in relation to the harbour entrance (even taken into account the possible current). This slight movement is a normal current movement. Very little on this image, but with a webcam completely zoomed out, a slight movement is quite a bit of meters. + Since we look at the webcam every night, we know the star and/or planets (bright points of lights which are only needle points)


58cE0o8ty4M





Here is a screen shot from the above video:



https://public.bay.livefilestore.com/y1p-KaS7NFRq4oaA1AlBgJhBvaD_whH6UddVkvdtV26UzsNkYmumGLx9DTUE4giaEIH2w8JxegQG8Y_ddWXt4fVQg/Image-2012-2-17-9h33mn16.jpg?psid=1





Compare it to this screen shot from the same webcam at a similar angle and zoom strength:



https://public.bay.livefilestore.com/y1pB4biZop3BRvOs6P6s0HpqLj-e3UPmz8nwT_sfnzxYMeZw4I4rloLvCqvLkIpRx6Hfu7tSsVy9e6XgYQyKtU6_Q/Image-2012-2-17-9h52mn45.jpg?psid=1




Match the harbor lights and... ER's SLSs are... "pie in the sky."


Another way to convince oneself the light in the video is a bright star/planet (amplified due to night setting of the webcam) is to follow the trajectory of said light... it goes down toward the sea while going westward.


Armand... please, scrape the guess work!

From Wikipedia: A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

Margalef has been all over the area for the lasr 2-3 days and has been stationary over a few spots, presumably performing water-column sampling/analyses.

Here is a summary of what could be seen on the different webcams:

On the panoramic views on the bottom ones, one may be able to notice the long-period waves/surf coming from the South-west.

Last ones: Jacuzzi-Margalef stand-off which lasted way into the night.

Polly is fast growing and is now only 100 meters away from reaching the surface!

That's 20-30 meters added to the cone since the last Ramon Margalef and Atlantic Explorer surveys!

Here is from europapress.es (http://www.europapress.es/islas-canarias/noticia-instituto-geografico-nacional-no-espera-fenomenos-eruptivos-superficie-hierro-20120228180934.html)
Martes, 28 de febrero 2012:



The phenomenon remains but with low seismicity

IGN does not expect the eruptive phenomena to surface at El Hierro

SANTA CRUZ DE TENERIFE, 28 Feb. (IRIN) -

The National Geographic Institute (IGN) has confirmed to the direction of the Civil Protection Plan for Volcanic Risk (Pevolca) that the process of normalization of the eruptive phenomenon of El Hierro is maintained in all parameters, with a marked decrease of seismicity, deformation and presence of associated gases, verifying only a degassing process in the area of emission.

In principle, surface phenomena are not expected to involve an increased risk for the population of La Restinga, even though the emission center is 100 meters from the surface as found by the Ramon Margalef, Spanish Institute of Oceanography at the recent work in the area.

Since the process is not over, the IGN will keep operating the 24 hours surveillance and volcanic alert and the Permanent Service Center in La Restinga, and continue the work of other institutions that are part of the Scientific Committee Pevolca such as the CSIC or Involcan.

Several state institutions have agreed an action program for the months of March, April and May, with different vessels assigned to the bathymetry with a periodicity of about 7 to 10 days.

The boats are owned by the Navy, Police, Marine Rescue Society, Ministry of Fisheries and the Customs Department, the Ministries of Defense, Interior, Public Works, Agriculture, Food and Environment and the Ministry of Finance and Administration public, respectively.


SMALL AMPLITUDE

Regarding the evolution of the phenomenon, tremor signal was recorded yesterday with small amplitude, with little variations, and there were 14 earthquakes of very low intensity. The highest magnitude reached 2.1 on the Richter scale and was felt by the population slightly.

The sign of the deformation recorded by IGN GPS stations located in the Gulf, show a slight tendency towards the north in the horizontal components. The rest of the stations and the vertical component remains stable.


Also of interest, is that with no vertical variations but with El Golfo moving horizontally North by a few millimeters indicates that the island is being "stretched" northward... definitely fissure phenomenon!

Here is a picture from Joke Volta (published by earthquake-report.com) which illustrates ancient "stretching" near La Restinga:


https://lh6.googleusercontent.com/-Y2BecP8ymf4/T0yU-fASugI/AAAAAAAALJA/HpI53hxnif8/s986/3+crater+monta%C3%B1a+restinga+which+I+visited+a+few+months+ago+and+allmost+could+not+get+out....jpg
Cinder cone at montaña La Restinga - proof of an historic eruption very close to La Restinga (before the village even existed) [comment: Armand Vervaek]


The craters alignment subparallel to the protruding dike (dark line on the cones flanks) indicate a "stretching" direction perpendicular to the alignment/dike direction.

It is the stretching which generates these cracks and fissures perpendicular to its extension direction. The cracks and fissures thus generated are then preferred channel-ways to magma emplacement and eruptive mouths/vents.

However, that stretching of the earth's surface is itself generated by magma chambers expansion at depth.

This, in turn, means that fresh magma is still being injected at depth and/or moving around!

[Edit]

Me think Joke Volta totally got the concept of "Fissure Eruptions" as demonstrated with this panoramic shot of the above close-up:

The calm before the 'storm', or a gradual relinquishment into the depths to 'snore' away for another few decades...? I reckon there will be a new island, but not a terrible catastrophe from slippage elsewhere. Celebrate a birth of a new island, and unless nature does not 'take its course' without some ghastly interference, we should look upon this event as astounding. Switch those damned machines off someone!!!

SEISMIC CRISIS SPECIAL - 03/06/2012 (14:00 pm)
ALL OF THE LAND AREA OF THE ISLAND REMAINS AT YELLOW

La Restinga is reinstated down to the yellow semaphore.


DIARIOELHIERRO.ES, writing (03.06.2012. 14:00)

The Minister of Economy, Finance and Government Safety Canary, director of Civil Protection Plan and Emergency Care for Volcanic Risk, declared the end of the emergency phase (red semaphore) in the maritime area of the eruption of La Restinga and established the pre-emergence (yellow semaphore) to the same area. It also keeps the yellow semaphore to the rest of ​​El Hierro's land area.

Regarding the security of the population measures, the direction of Pevolca has abolished the terrestrial exclusion zone between White Sands, Los Tacorón and Los Mozos beach, but maintaining the maritime exclusion zone in the vicinity of the eruption area, although reduced in distance. This will be materialized by the Harbour Master in a resolution so that until the document is issued, the 4 miles original exclusion zone is maintained.

THE RECOMMENDATION OF NO SWIMMING REMAINS

As for aquatic activities in the area of La Restinga-Tacorón, the recommendation to avoid swimming and diving, fishing and shellfishing remains.

The direction of the Plan continues to take water samples for analysis which results will allow the Public Health Department to update the recommendations in this regard.

Results

The main morphological differences found in this new survey conducted over the previous one, 15 days ago, are:

• A succession of cones between the primary and secondary cone that form a ridge NNW-SSE direction coincident with the the Rift axis south of the island.

• A slight increase of deposits volume, especially on the upper cone that has brought its elevation to a depth of 88m.

From the point of view of observed volcanic activity in the water column, there is a significant reduction in the presence of emission plumes and a complete disappearance of noise in the echograms.

Of particular interest in that publication:


Cone

The new survey clearly shows the alignment of the different active emission points giving rise to a 675 m long ridge, along a NNW-SSE direction. Depth increases in the 154° direction along this ridge.

The highest point of the volcano is located at 88 m depth, representing an increase of 32 m from the last bathymetry performed on days 7 and 8 February.

The coordinates of the main summit remain: 27° 37.18' N, 17° 59.58' W.

The gradient of the volcano slope varies between 26 and 33 degrees, with the greatest trending to the SW surfaces and stretching out to the SE.


******
Text and captions retranslated from Giggle, reworked and corrected "par moi" since in one of them one can happily read that the depths of the different cones forming the ridge decreases toward the SSW [sic]... where, in fact, it either decreases towards NNW or increases towards SSE... the SSW direction corresponds to no mapped features.

Conclusion... another rushed job under high pressure to get it out ASAP!

However, all in all, I am actually glad IEO does publish their results as it allows some of us to have something to chew on and with... a big thanks to the IEO gals and guys!

That is, especially those ones:

SPECIAL SEISMIC CRISIS - 9/3/2012

DIARIOELHIERRO.ES, writing (09/03/2012)
The Maritime Authority of Santa Cruz de Tenerife, in a decision issued today, limits the maritime exclusion zone to a 0.5 miles [nautical] radius area around the underwater volcano of El Hierro. This sector is defined by the area within a circle centered at Latitude 27-37.18 N and Longitude 017-59.58W.

This decision is taken after reduction of the level of public warning, by the Director of Civil Protection Plan for Volcanic Risk (Pevolca), after the emergency phase and declared a pre-emergency situation in the area of maritime exclusion.

Also in this sector are prohibited all fishing activities, sport and recreation are made from or with the support of boats, including diving activities either sports and / or recreational.

Navigation justified in that area, whether due to technical and / or scientific reasons, can be made with the prior permission of the Harbour Master.

[Hervé]

To give an idea of where Polly's top cone is located on Google Earth with respect to the webcams and La Restinga harbor entrance as well as the length and orientation of the whole emission fissure:

From Wikipedia: A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

Ooooopsss... Polly's still bubbling!

It's unfortunate that the following is authoritatively proclaimed on Earthquake-report.com, flying in the teeth of observed facts:


Update 10/03 – 17:55 UTC
- We have checked and and it WAS NOT a jacuzzi. Joke Volta has confirmed this to ER.

Update 10/03 – 17:25 UTC
- What looks like a waves breaking at the eruption webcam has been observed in the past minutes, but it is probably the effect of the wind and/or currents.

From the webcams (paying attention to the time stamps as well as to the Jacuzzi):

The activity then subsided to re-emerge later in the evening:

Notice the Harbor entrance green light at the bottom of the above pictures, which gives a reference indicating the Jaccuzzi to be in the direction of the main vent (see the Google Earth locations in above posts, as taken from the webcams location).

I do hereby confirm these observed churned waters above the main vent to be a Jacuzzi! Not the interaction of waves and currents.

[sygh]

Excellent work, and observations.

[Hervé]

Another statement on Earthquake-report.com which fails to hold much water... so to speak:



Update 10/03 – 21:45 UTC
[...]

- Joke Volta has spoken with Ramón Ortiz and here we have translate his words for what he believes could be happening:

” What can be observed now we saw 2 weeks ago. I have looked at the seismic network, and there has been no variation, no anomalies. When there is an eruptive activity this is reflected in the seismic network. What could be happening is that as magma is still hot, it takes time to cool down, this material is still releasing heat and vapor, and there is still gas release. That is why there is still an exclusion zone around the volcano. Tides can affect the process that we see. As the tide changes, the pressure does too and this can alter what is happening. The effect of the tides we have observed it two weeks ago when there was a decrease in activity. The visibility of the volcano changes and this is also due to the tides.

Can you spot why that statement is as waterproof as a sieve?

Well, from my point of view, if that statement were true, that water churning would be continuous... not intermittent as observed.

The sporadic emergence of a Jacuzzi above the main vent has to, therefore, correspond to new heat and gas input... if not magma!

So, may be, we'll get fresh data and first-hand view of Polly if they manage do get their ROV anywhere near the active vent... to be followed.

Hi..

Is the people on this island in constant fear? or has it subside over time?
I guess it would only be normal for some people to finally get tired of being afraid.

Please forgive me I am not here to judge and I obviously don't have all the facts, I just noticed the neverending updates on this thread.
I guess one could say, come back when you got your own volcano in your living room, to that I would answer. I would rather kill myself then live in fear..

P.S...I do hope everything works out, this is your journey, live it well my friend..

Polly's been bubblingly giggling most of the afternoon and evening... probably because still alive and kicking when most of the authorities wish her dead and burried for good so as to return to "businees as usual" as exemplified by these statements from Earthquake-report.com:


Update 11/03 – 18:38 UTC
- Images Joke Volta from today showing a beautiful sunrise and a few images with a super faint jacuzzi. Click here (https://picasaweb.google.com/110327184570944806725/ElHierroMarch112012?authuser=0&feat=directlink).

Update 11/03 – 21:34 UTC
- Today a number of people and Joke saw a faint jacuzzi or rather degassing in the vent area. This was also confirmed by scientists.



Don't now about you, but if there is "degassing," water is churned and therefore... Jacuzzi!

As for "super faint," here are a few screen shots:

After nearly a half year of being one of the forums most read threads, and after nearly 2000 posts, we are renaming this thread to have a more accurate title. The "evacuation" has been called off and the alert level has gone back to "Yellow."

Old thread title:

After tirelessly updating Avalon for weeks...it's official, evacuation is in progress
New thread title:

Tirelessly updating Avalon on the El Hierro eruption.

I am impressed at how skilled the webcam operators have become in the handling of their toys... almost as skilled as the Atlantic Explorer's skipper in coasting his ship!



On another hand...


According to Earthquake-report.com [has been reworded now] there was something looking like a Jacuzzi on the Las Calmas Sea's surface this morning that could have been related to a stain/plume observed by Joke Volta later on in the day...


If they continue in that line of thinking/wording, they'll end up writing something like:


" It seems that there could possibly be a submarine volcano south of La Restinga that could possibly be related to all these phenomena that are alegedly observed at sea surface since we are not discounting mirages or camera artifacts nor weird interaction between sun scintillations, waves and local currents...."


Oh, well... English can be tricky as a second or third language... I guess... since it's only my second language.

From Wikipedia: A Harmonic tremor (http://en.wikipedia.org/wiki/Harmonic_tremor) is a sustained release of seismic (http://en.wikipedia.org/wiki/Seismic) and/or infrasonic energy typically associated with the underground movement of magma (http://en.wikipedia.org/wiki/Magma) and/or venting of volcanic gases from magma. Being a long-duration continuous signal from a temporally extended source, a volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as tremors that are typically associated with earthquake and explosion.

Thank you for all your vigilance, here, Amzer. I've been aware of this situation all the way back to 05, or 06 when that documentary 'Mega Tsunami' first aired. Since I live on the New Jersey Cape at about 8 feet above sea level, I'm keeping an eye on this. Here on the Cape, we are really on a sandbar out in the middle of the Atlantic Ocean.

Gee....what happenied to randles? Isn't this her thread?

Correct about this thread being started by randles, however, if you did follow this thread you may have noticed randles went AWOL in November 2011...

Good for you if you can bring her back!


I have gone over the thread, yes all of it, and I don't think she went AWOL so much as she conceded to you commendeering her thread. I'm glad to know she is OK knowing that she started this thread so that those interested here would know that as she gave us her daily report. Thanks randles for keeping us posted. I wonder if she knows she can close the thread if she wants too?

Hi observer!

I can understand your concern over a well publicized and orchestrated fear propaganda campaign, and that's the crux of that matter: it was an add campaign in disguise for insurance companies (see post # 739 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=327913&viewfull=1#post327913)).

See this post for the latest on that "megatsunami" saga: http://projectavalon.net/forum4/showthread.php?42384-Fulford..Announcement-aired-live-on-March-13th-on-the-internet&p=447852&viewfull=1#post447852 (http://projectavalon.net/forum4/showthread.php?42384-Fulford..Announcement-aired-live-on-March-13th-on-the-internet&p=447852&viewfull=1#post447852)

For other posts on that same subject in this thread, a good one to start from and follow the links from there is this one: Post # 1829 (http://projectavalon.net/forum4/showthread.php?30888-After-tirelessly-updating-Avalon-for-weeks...it-s-official-evacuation-is-in-progress&p=384546&viewfull=1#post384546)


For the time being and from where you stand, I'll be more concerned about HAARP enhanced storms/hurricanes in your area than a hypothetical tsunami managing its way across the Atlantic.

But that's another topic...

CHIE station (El Hierro) has been tweaked so as to filter out any non-local events.

Randles left - end of - she was quite rude to anyone with any other views. Amzer has been logical throughout. I am happy to see Amzers regular reports - we are very grateful for all the science background. Hopefully 'Randles' is back with her husband and family, and not in any crisis situation any more. We thank her for her original post, but we also must thank those who have kept up the real scientific information. No panic unless science eh?

Thanks again Amzer,

I've seen most of the evidence from both points of view. I'm an evidence kind of guy, so I think it's important to look at as much - both historic and scientific - as one can.

I personally don't think the H.A.A.R.P. issue is "another topic" at all. I submitted my original 'thanks' because there is a need for vigilant observers to stand on the perimeter of reality in the capacity of a sentry for the protection of the human condition.

Thanks for the feedback observer.

"Another topic" omitted: "as far as this thread is concerned," meaning that it could be the subject of another thread.

Otherwise, yes HAARP and radar arrays can get their cotton picking wavy fingers into about anything and I have been debating that point in many posts about the so-called Japan earthquake and its accompanying tsunami disaster.

I thought Atlantic Explorer had gone home and was surprised to see the now familiar silhouette reappear on the screens:

Quite a roller-coaster at sea, today, for a small vessel....

Notice that the ACNpress webcam will quit streaming this weekend... too bad since they have been the most reliable visual source for the area. A big thanks to them!


Hopefully we'll soon get some real life shots of Polly, if the Atlantic Explorer crew manages to publish them somewhere... to be followed.

Looking at the Harmonic Tremor getting fluffier and revving up the higher frequency domains (gradiently changing from deep blue to pale blue to turquoise to yellow on the above Harmonic Tremor graphs) I wondered what was happening to the ground deformation according to these GPS graphs... and... :frusty: ... did I ever hit a snag!

No wonder Geolurking ran into trouble with dear Nemesio Perez...


[Start rant mode]


:rant:


See, when one goes past the eye-candy graphs on the IGN page (http://www.ign.es/ign/resources/volcanologia/html/deformacion.html), one may realize as I did, and Geolurking long before, that these graphs are totally useless!


Why?


No frame of reference given!


That translates into no indications whatsoever as to which direction the positive displacement corresponds to: is it straight line? North component? South component? East component? West component? Up vertical/oblique? Down vertical/oblique? With respect to what taken as the immobile centre of coordinates... Ouagadougou? Vega? Orion? Galactic Centre?


Moreover, it seems that IGN also resets the "Zero" displacement from time to time to one of the already displaced, prior position as exemplified by this graph from marcelo at Todogeologica.com (http://tenerife.todogeologia.com/viewtopic.php?f=1&t=1824&sid=69f2aa61ac71c8eb4f2f840916babeed):


http://i1083.photobucket.com/albums/j384/marceloantonio/vardistancias15_8.jpg

In the present, data on the deformation of January (blue graph) in the graphic by CalidoT, the graph that shows the current data from the IGM [IGN]. (brown graph), and values ​​that IGM [IGN] should put. (green graph)

As you can see the legend in the third graph is marked with question marks because the data given by CalidoT also start from scratch since Aug. 15, but we did not consider at that time the value of the deformation, with two-month and would have to have values ​​much greater than zero. With the current strain, these stations would be higher at 24-25 mm from the green graph.



See? A ground strain/deformation translated into the displacement of one of its point is decomposed into three components along three orthogonal coordinate axes from an original position at the intersection of these axes:


http://www.mathsisfun.com/data/images/cartesian-3d.gif
Here the point (2, 4, 5) is shown in three-dimensional Cartesian coordinates X, Y, Z.


IGN just moves the axes' intersection to the new position and continues from there... hope I am wrong, but that's what it looks like...

One would also assume that the X and Z axes above belong to the horizontal plane but there is no indication on the IGN webpages that they indeed do use such a reference frame... could very well be a slented plane as far as I can ascertain!

So, when Carmen Lopez or Maria Jose Blanco mention that there is a northward motion of some part of El Hierro island... Hummmhhh... that could very well mean that the entire African plate moved northward by a few millimeters... :frusty:

All right, finally!

Polly has been spotted and recorded on digital media spewing fresh lava when the scientific aristocracy decided to be done and over with her...

Here is from AVCan Enrique (http://www.facebook.com/pages/Actualidad-Volc%C3%A1nica-de-Canarias-AVCAN/163883668446):


To kill the itch waiting for the images of the volcano obtained by the ROV SOS Atlantic Oceans on the Explorer, where it seems that images of the submarine volcano are clear enough, and even seems to have captured the exhaust of fluids and .. of LAVA in one of the craters; I leave you this video of Feb. 26 in Puerto de la Restinga as an appetizer, it's amazing the amount of bugs that swarm through the bottom of this port ... (Enrique)

I think that's befitting for the 2000th post dedicated to the growth of a submarine volcano.
