''The risk of landslides is a constant concern''

The island of El Hierro, of volcanic formation, faces risks of landslides in areas of natural terrain committed to the Geological and Mining Institute (IGME) will be analyzed for their proper management.

The study director, Mercedes Ferrer, told Efeverde that the stability of rocks in areas close to roads is a "constant concern" in an area, as the island of El Hierro, high geological activity.

The purpose of IGME is to "assess the stability of slopes in some areas with danger of detachment that are now closed to traffic" and other potentially dangerous by its geography, topography, height of the cliffs or frequent incidents of landslides, explained the expert, who will travel to El Hierro this week, along with other experts from IGME to undertake the fieldwork.

"Our work is based on the observation and study of the land, then be responsible for defining other corrective measures," said Ferrer, a specialist in landslides.

The rockslide in El Hierro are processes that may relate to frequent earthquakes, but not with phenomena such as volcanic eruption recorded recently, said the geologist of IGME, which identified them as natural expressions of the geological evolution of the Canary Islands.

He noted further that the engineering works and heavy rains to be taken into account in assessing the risks involved surveying landslides still strong as basaltic rocks of El Hierro.

Ferrer also said that in the Canary Islands, despite its well-known seismic activity is not binding on the seismic resistance building code in force in Spain and that does apply in other seismic zones as the provinces of Granada, Murcia or Alicante.

"Canary Islands is a sparsely investigated and a sparsely instrumented so far, despite being the most geologically active than we have in Spain," he said.

The behavior of volcanic rocks, such as El Hierro, said they are generally stable and are broken into relatively small blocks, but with the risk of detachment is necessary to consider other values ​​such as speed and steepness of the drop.

"The danger is not the size of the block, but the speed with which it falls and where it falls," he said, before pointing out that this information is essential to develop plans for prevention and mitigation.

El Hierro, the westernmost of the Canary Islands, has experienced over the last three months up to 10,000 earthquakes and volcanic eruptions, underwater two, one at 5 kilometers from the coast and about a thousand feet deep, and another 3.5 miles south of La Restinga, 600 meters below sea level.

Finally found out why "Leon Thevenin" is drifting around Santa Curz:

From: http://earthquake-report.com/2011/09...sed-to-yellow/


Update 13/10 – 13:57 UTC : Our dreams will finally not come true! What happened? The French cableship Leon Thevenin was making cable inspection trips for the Spanish telecommunications company Telefonica. Telefonica, aware of what looked as a unique way of using the technology aboard the ship, offered the ship to the authorities. However …. negotiations (probably to charter the ship) did not deliver result as the ship is owned by a consortium of France Telecom, Portugal Telecom and Telefonica and talks were broken off.



Update 13/10 – 16:47 UTC : An additional note why the Leon Thevenin will not be contracted. The main issue in not sending the ROV ship to the area is that the Canary Governments did NOT want to take the risk that a ROV would be damaged or even destroyed, a condition that Telefonica consortium was setting before the Leon Thevenin would sail out. We @ earthquake-report.com can understand such a position from the local government, but we remind Mr. Zapatero on his Monday formulated words “everything which is needed”



Update 13/10 – 17:56 UTC : Diario de Avisos reports that the ship ‘Ramon Margalef‘ currently anchored in Vigo, will navigate towards El Hierro and arrive there on Tuesday. The Ramon Margalef will carry the ROV “LIROPUS 2000″, a remotely operated vehicle able to dive to depths down to 2,000 meters.
The “Ramon Margalef” is one of the newest ships from the ‘Instituto Español de Oceanografía”.
The crew of the Ramon Margalef will consist of geologists, biologists and physicists.
We enjoy this news at earthquake-report.com, hopefully not too late.

Update 14/10 – 09:21 UTC : The press people are all returning their back to La Restinga and the lava area in the sea and are heading for La Estaca, the port where the ship “Profesor Ignacio Lozano”‘ WITHOUT a ROV is awaited. This ship will enter the ‘supposed’ eruption waters and will take and analyze many samples. Another ship with a ROV aboard will set sails to El Hierro on Monday and will hopefully arrive at the eruption spot on Tuesday. This ship will enable us to see what happened at the Ocean floor.

EFE / Madrid

The 1803-02, scientific name of the volcano El Hierro

An accident of geography, mythology, folklore and popular imagination are the usual origin of the name of the volcanoes, which in the case of El Hierro is known by scientists with the 1803-02 numbers.

These numbers identify the volcano: 18 corresponds to the region (Spain), the 03 to the subregion (Canary Islands) and 02 the number of the volcano (the 01 is the Teneguía in Palma, and 03 is the Teide in Tenerife).

Speaking to EFEverde volcanology professor of the Complutense University of Madrid, Eufemio Ancochea, said that most volcanoes are related to the mythology of cultures and sacred places.

In the unlikely event that a new volcanic island arose as a result of the eruptions in El Hierro, Ancochea said that "there is no criterion to give a name, unless the fishermen referred to in some way to that area."

The area where the two eruptions have occurred is known as the sea calms.

Today, the research vessel "Professor Ignacio Lozano" arrive at the port of Stake in Valverde (El Hierro), to assist in the management and evaluation of submarine eruptions that have occurred in the vicinity of La Restinga.

From this ship will be several vertical profiles of physicochemical parameters and geochemical as well as dissolved gases in water.

The stains generated by underwater eruption in the sea of ​​moving towards the coast of restinga ... these are the latest images taken by a Civil Guard helicopter that place a little over a mile from the village of La Restinga. They can see that they have acquired a tan that scientists believe may be due to an issue fumaroliana to a depth of 150 meters. The Renewable Energy Technology Institute have warned that carbon dioxide emissions have exceeded the normal values ​​of 339 tons per day to 990 have gone with something more cyclical vibrations of volcanic tremor reflect the movement of magma in the subsurface of the island. The stain is visible from space.
In addition, the National Geographic Institute has said that magma has already begun to go in a straight line eastward into new cracks closer to the coast.

A satellite photograph of El Hierro weeks before the eruption


http://www.diarioelhierro.com/
IRIN, Madrid (10.14.2011. 13:56 pm)

The imaging satellite Envisat medium-resolution spectrometer has photographed the island of El Hierro on 8 September, about a month before a volcano erupted underwater.

Thus, the European Space Agency (ESA, for its acronym in English,) comments on El Hierro that earlier this week, the submarine eruption of a volcano on the southeastern coast of El Hierro forced authorities to evacuate hundreds of residents of the smallest island of the archipelago.

In addition, the photographs also show the west coast of Africa and the Canary Islands subtropical, which indicates that its favorable climate and beaches, attract 12 million visitors a year, and that some of the visitors to go to the Canarian beaches are surprised to see the many contrasts in dark blue waters of the north.

This is because the archipelago is away from areas with lots of light pollution in large cities and its location "ideal" for astronomical observations. Thus, says the island of La Palma is home to the observatory of El Roque de los Muchachos, while Tenerife with Teide Observatory.

ESA also noted that Tenerife has the third largest volcano in the world, Teide, and that the similarities environmental and geological conditions between the Teide National Park and the planet Mars have led many specialists to travel to the island with material and instruments for testing in order to travel to Mars someday.

RTVE.ES / AGENCIES - Valverde (IRON) 14.10.2011 - 17:34 h

The research vessel "Professor Ignacio Lozano" has docked at about 17.00 hours on Friday at the port of Stake in Valverde (El Hierro), according to RNE, to assist in the management and evaluation of underwater eruptions that have been produced in the vicinity of La Restinga. This ship will join in the coming days another, the research vessel Ramon Margalef, Spanish Institute of Oceanography (IEO).

From this ship, owned by the Canarian Agency for Research, Innovation and Information Society of the Canary Islands, will be different vertical profiles of physicochemical parameters and geochemical as well as dissolved gases in water, after last night was detected an earthquake, which occurred at 00.51 hours, at magnitude 1.7 on the Richter scale at a depth of 16 kilometers.

The "Professor Ignacio Lozano" has come to El Hierro after 25 hours of journey, from it's base in Taliarte, on the island of Gran Canaria, with several hours of delay dur to the poor state of the sea, and six scientists traveling aboard from different agencies.

At the moment there are meetings taking place to discuss whether the ship will sail this afternoon to La Restinga or whether it will do so tomorrow, according to RNE.

Carlos Barrera, a researcher of the Continental Shelf of the Canary Islands, explained to journalists that the ship is equipped with instrumentation to measure parameters such as salinity, turbidity, chlorophyll, temperature or water in the area.
An opportunity to study the phenomenon

Barrera has highlighted the opportunity of studying a phenomenon like this, which is unpredictable and unknown, and therefore scientists take all protective measures are necessary.

Barrera explained that the implementation of the "Professor Ignacio Lozano" has a probe to obtain samples to a depth of 1,500 meters.
Another ship will assess the situation of the sea

Furthermore, to assess the condition of the sea, where they have located two sources of underwater eruption southwest of La Restinga, one to two nautical miles (3.70 kilometers) from shore and 750 feet deep and another 1.5 miles (2.77 miles) and 500 meters under the sea, is expected to send the Spanish Institute of Oceanography Vigo on Monday from the ship "Ramon Margalef", a ship with a submarine robot.

It is a floating laboratory robotic submarine that carries Liropus 2000, which may extend to two thousand feet deep.

The "Ramon Margalef", which is in Galicia, is a ship of 46 meters in length with a system of double helices of five wings, capable of carrying eleven investigators, in addition to the twelve members of the crew.

"The eruption could come to eject the equivalent of 40,000 Olympic swimming pools of lava"

IRIN, Madrid (10.14.2011. 19:05 pm)

The submarine eruption is occurring in the area near La Restinga could drive "at most" 0.1 cubic kilometers of lava, ie, equivalent to 40,000 Olympic swimming pools, according to volcanologist of the Higher Council for Scientific Research (CSIC ), Joan Martí.

Marti explained that "you can not determine" the total volume for the moment, it is unknown how much lava is coming out but, in his view, the maximum volume should not be out "very different" to the historic eruptions in the Canaries . "At most it may be lava output of 0.1 cubic kilometers maximum volume is large but not very important in these magnitudes. This would amount to about 100 million cubic meters or, which is the same, about 40,000 Olympic swimming pools, "she added in remarks to Europa Press.

In this context, explained that this volume will continue to contribute to the construction of an underwater mountain range that takes thousands, millions of years forming south of El Hierro and therefore "this episode of eruption is more within a building the area, so from this point of view, this should be seen as part of the normal. "

On the material that is coming out abroadhe, said that molten basalt is mainly touching the water cools and becomes rock and as the turquoise blue of the stain is seen on the water, explained that "probably" will be due to remobilization of sulfur and clay from the ocean floor that gets stirred up and becomes turbulent waters.

SITUATION "CONSTANT"

The volcanologist has said that at present the situation continues and is "constant" so that the eruption is constant, ie, the magma that is coming through a crack and can have several points of fissure more concentrated. "Hopefully this situation will continue for days or even weeks, depending on the amount of magma that has to leave," he added.

On the other hand, from the point of view of the involvement of the ecosystem, has emphasized that the eruption is a natural process, so that nature is "wise enough to self-balance itself." Furthermore, this type of eruptions are "very common" normal in these volcanic areas.

In fact, he added that there had been "many eruptions" of this character in the area, even in recent times, only they were not observed because there were no current devices, but in this case "yes" is being pursued because there is appropriate instrumentation in the right place.

Therefore considers that there will be little change from the environmental point of view because these ecosystems recover "very fast". Marti believes that if an eruption in the middle subaerial environment recovers so fast, submarine eruptions in "much more", so that the impact will be "minimal."

In any case, acknowledged that the gases are mixed with water, mixed with sulfur are not very good at these depths, but gradually be balanced ecosystem, because it is diluted quickly once cool the lava that have come .

Precisely, said fish deaths occur because this material is washed out "en masse" but when the eruption stops or recess, will return to the previous situation, without causing serious problems.

On the other hand, does not exclude the "possibility" that if the fracture is prolonged to subaerial part of the island, it can cause a rash on the island of El Hierro, but has "the feeling" that the situation is "quite stable "and is relaxing on a continuous basis, so there is no effect of overpressure.

The odds, with caution, would be low, but can not be excluded. I would not give many chances, but a possibility exists and should be taken into account.

Some 40 experts

As for the scientific team that is deployed in El Hierro, said that the National Geographic Institute, there are 30 people, including technicians and scientists and 10 other people of the Higher Council for Scientific Research (CSIC). There are other scientists and interested in the topic. In control of the situation and responsible for volcano monitoring would be looking at between about 40 people.

As a volcanologist, Joan Marti pointed out that the situation has gotten along well from the beginning, because they have done things "as they have to do," since the beginning of the abnormal situation to date. On the performance of the National Geographic Institute believes that it has been "perfect" and has also emphasized that have been applied "good" emergency protocols Canarian Government.

From the scientific point of view, has assessed that the situation raises "a great interest because it is the first time you have a complete record from the beginning to the end of an eruption." He has also held that, subsequently, will have to analyze the data, for a long time to interpret and make this information would be beneficial for other areas or for the same in the future.

Recent peek from space:

[Hervé]

Scientists focus on whether magma or only gases emissions
Loreto Gutiérrez / Las Palmas de Gran Canaria

Not all scientists think the same about the volcanic phenomena of El Hierro. Vice President of the Association of Geologists, Jose Luis Barrera, doubt that the volcanic fissures detected on the seabed off El Hierro have been drooling magma as has been said. "It has been said that the lava has come to surface and that is incorrect, because the lava first never floats up and especially because it is still unknown whether lava was expelled since no one has seen it, he says.


For Barrera, the only evidence is that there has been a release of gas at shallower depths for three days, which has enabled "bubbling out to the surface." In any case, it is deemed necessary to wait for the analyses of the patches that have appeared in the ocean in order to know its exact composition.


The expert geologist also considers "very interesting" to have a boat with an underwater robot to see what is happening under the sea. "We will see if it's gas only or if it also oozes out lava," he says, "and that helps create the eruption pattern of the area for when there is another similar situation." Barrera believes that, since the earthquakes have almost disappeared, for now, "there is a risk that may arise from other volcano in the north-south band in which there have been previous seismic crisis," while acknowledging that such an evolution is difficult to predict .

WE KNOW IT"S MOVING. "What is known is that the magma just below keeps moving, because the seismic signals so indicate" he states, "It is true that it appears to move with less force, perhaps because the gas has been released through the fissure, but it keeps moving and we have to keep watching to see how the movement evolves," he adds.


If an eruption were to occur around one hundred meters deep, which implies a closer proximity to the coast of the island, the vice president of the Association of Geologists warned it would be "riskier" than an eruption on the ground.


"When an eruption occurs at more than one thousand meters, the water pressure does not allow any visual manifestation to escape to the surface, only the temperature can be measured", he explains, "but with a hundred meters or less of water column, it can have an impact and may have more serious consequences since the mouth of the volcano turns water into steam, the vapor pressure is greater and the fragmentation of the magma is much higher, and that's always more dangerous than an eruption on land that has no water " .
