Reactivation of the volcano in Ecuador

In the afternoon, at approximately 17:30 (local time) an increase in volcanic activity that caused the decline of several pyroclastic flows were recorded.

There have been reports that the flows reached the Chambo river drains the western side of the volcano. Preliminarily it has been determined that the column reached more than 10 km above the volcano's summit height, according to a report from the Geophysical Institute of the National Polytechnic School.

The Geophysical reported that the 14:37 column reached 2.5 km high and 3 km in the second issue of 17:13.

It was confirmed that the closure of the road in the Los Birds joins Ambato and Baños, because there pyroclastic flows.

The ambateños are expectant. "I'm a little nervous. Of all the 14 years he has been active, I've never seen such a big mushroom, "says Álvaro Proaño.

Report Risk System

This afternoon, the Tungurahua volcano showed a significant increase in activity with the generation of eruptions accompanied by pyroclastic flows that have suddenly fallen to the lower parts of the volcano.

At 17h12 and 17h32 moderately sized two explosions with ash plumes of 5 km above the summit were recorded and generated pyroclastic flows that descended about 500 m in the north-eastern and north-western flanks.

These explosions were followed by a larger explosion at 17h39, it initiated a sustained emission of ash that quickly reached 8 km in height.

Immediately after violently down on all sides of the volcano (NW flanks, WE NE and SW) pyroclastic flows that descended into the lower parts of the cone. Flows reached the bottom of the ravine cutting Achupashal Baños-Penipe pathway.

Ash flows impacted monitoring instruments in the ravines of Vazcun, Achupashal, Juive. Emissions of ash and pyroclastic flows continue to decline until this hour.

In addition the level of seismic activity at the volcano remains high, which was posted 50 long period events, 60 events volcanotectónico, 1 blast and 2 episodes of tremor of emission. This behavior began Thursday after registering several minor explosions broke almost four months of relative quiet on the colossus.

The Tungurahua, 5,016 meters high and located about 80 kilometers south of Quito, their current eruptive process began in 1999 and since then has periods of intense activity interspersed with periods of relative calm. This colossus integrates more than fifty volcanoes are there in Ecuador and along the Reventador and Sangay is one of the busiest in the country.

A person on the ground in the area whom we are in contact with has said their operations are currently curtailed as they have been told to not move around into the wilderness regions.

UPDATE: It appears that pyroclastic flows are crossing the road at Los Pajaros.

UPDATE 7:15 PM EST: Some reports are now putting the ash plume height at 10 km / ~32,000 feet while the Washington VAAC advisory mentions ash as high as 14 km / 47,000 feet. According to the official IG-EPN report, pyroclastic flows apparently moved down the slopes of the volcano in all directions as well.

Tungurahua - the volcano called, the Throat of Fire

http://en.wikipedia.org/wiki/Tungurahua

The volcano gives its name to the province of Tungurahua. It is an active stratovolcano located in the Cordillera Oriental of Ecuador.

http://chanlo.com/images/volcanoes_ecuador.jpg
The above shows the locations of the major volcanoes of Ecuador.

Background: Nearby notable mountains are Chimborazo (6,267 m) and El Altar (5,319 m). It rises above the small thermal springs town of Baños de Agua Santa (1,800 m) which is located at its foot 8 km to the north. Other nearby towns are Ambato (30 km to the northwest) and Riobamba (30 km to the southwest). Tungurahua is part of the Sangay National Park. All historical eruptions originated from the summit crater and have been accompanied by strong explosions, pyroclastic flows and sometimes lava flows. In the last 1,300 years Tungurahua entered every 80 to 100 years into an activity phase of which the major have been the ones of 1773, 1886 and 1916–1918.

In 1999, after a long period of quiescence, the volcano entered an eruptive phase that continues to this day (as of January 2013).

The renewed activity in October 1999 produced major ashfall and led to the temporary evacuation of more than 25,000 inhabitants from Baños (less than 5 miles away) and the surrounding area.

Activity continued at a medium level until May 2006, when activity increased dramatically, culminating in violent eruptions on 14 July 2006 and 16 August 2006.

The 16 August 2006 eruption has been the most violent since activity commenced in 1999.

This eruption was accompanied by a 10 km high ash plume which spread over an area of 740 by 180 km, depositing ash and tephra to the southwest of the volcano.

Several pyroclastic flows were generated that killed at least five people, and destroyed a number of hamlets and roads on the eastern and northwestern slopes of the volcano.

A further eruption and evacuation occurred on 4 December 2010.

Ecuador's National Agency of Risk Control issued a "red alert", later downgraded to orange.

The Ecuadorean Institute for Geophysics reported a rapid increase in seismic activity, a number of explosions and an ash cloud reaching 2 kilometres (1.2 mi) in height.

Another eruption occurred on 18 December 2012 forcing evacuation of those living on the volcano's slopes.

The volcano erupted again in July 2013.

On 1st February 2014, the volcano erupted again.

Ash cloud has climbed more than 2.5-mile-high (4-kilometer) from Tungurahua volcano on Monday and has affected a third of Ecuador's provinces and forced the suspension of classes at some schools after temporarily closing a regional airport. QUITO, Ecuador --

A series of 10 powerful cannon-like blasts shook the 16,480-foot (5,023-meter) volcano overnight and could be heard for miles.

Tungurahua is nearly 90 miles (140 kilometers) south of Quito.

Government officials distributed masks to protect them against the inhalation of ash.

ACTIVITY UPDATE:

see link: http://www.volcanodiscovery.com/tungurahua/news/42378/Tungurahua-volcano-Ecuador-activity-update.html

Yesterday, small explosions and ash emissions were recorded. At 10:40 local time, an episode of harmonic tremor with a deep origin was recorded, suggesting that more magma might be rising from depth.

Last night and this morning, there were at least 10 explosions of moderate size which could be heard as heavy gunfire and lasted several minutes. Some were so intense that they could be heard several kilometers away.

An ash column rose about 4 km above the summit during the largest explosion and drifted northwards.

IGPEN writes that the most likely scenario for the near future are continuing discrete explosions of similar size as yesterday and today, accompanied with strong ash emissions, causing ash fall and possibly pyroclastic flows.

A second most likely scenario is that activity declines at the surface while internal pressure builds up towards another major explosion.

Both scenarios involve a high risk for anyone in the areas close to the volcano, in particular low-lying areas in and around valleys draining from the mountain, at several (5-10) kilometers distance.

Potentially heavy ash falls can be expected in areas lying in the main wind direction and is likely to seriously affect agriculture, livestock and of course the health of the people exposed to the ash. Furthermore, ash plumes from the current activity are a serious hazard to air traffic in the area.

There is a short 2 minute flash video at http://www.sangay.com/travelnews/mount-tungurahua-volcano/ which has supplied some of the data about Ecuador's volcanic distribution.

From the page:

Follow the evacuation order issued by authorities and evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast, and lava flow.

Be aware of mudflows. The danger from a mudflow increases near stream channels and with prolonged heavy rains. Mudflows can move faster than you can walk or run. Look upstream before crossing a bridge, and do not cross the bridge if a mudflow is approaching.

Avoid river valleys and low-lying areas. (Banos is in the area)

Remember to help your neighbors who may require special assistance – infants, elderly people, and people with disabilities.

Watch for falling ash…

If you have a respiratory ailment, avoid contact with any amount of ash.

Wear long-sleeved shirts and long pants.

Use goggles and wear eyeglasses instead of contact lenses.

Use a dust mask or hold a damp cloth over your face to help with breathing.

Stay away from areas downwind from the volcano to avoid volcanic ash.

Stay indoors until the ash has settled unless there is a danger of the roof collapsing.

Close doors, windows, and all ventilation in the house (chimney vents, furnaces, air conditioners, fans, and other vents). Place towels under doors and in other gaps.

Avoid running car or truck engines. Driving can stir up volcanic ash that can clog engines, damage moving parts, and stall vehicles.

Avoid using electronic devices where there is still airborne ash, as it can short circuit electronics.

Once airborne ash has completely cleared, ash should be vacuumed, not wiped, to prevent scratching on surfaces like porcelain, enamel, glass, painted surfaces and appliances. A damp cloth may be used after initial vacuuming.

Change vacuum filters frequently, and be careful your vacuum is not redistributing ash through the air discharge.

Clothing exposed to ash should be shaken out and put through a rinse and pre-soak cycle before machine washing. Use extra detergent. Laundry additives can help adjust the pH level and make detergents more effective.

Tungurahua attracts the major news coverage due to its recent activity.

Ashfall is a problem with swimming pools in the hotels, clogging up the filters, and shutting down recreation when the events happen.

http://i0.wp.com/www.sangay.com/ecuadorguide/wp-content/uploads/2011/04/Banos-termal.jpg
(above shown in a local Banos hotel pool - vendors and operators prefer to close their operations when there is ashfall, even in the local thermal pools, which are an attraction for tourists in the area)

Due to the prevailing winds, the ashflow generally moves in this direction:

As far as I can see in the volcanic map, Vilcabamba is far south 150-200 miles, of where the volcanoes are in that range, where the winds blow is what I am looking at, time of year, winds aloft, ash plume prediction based on past eruptions.

I have an associate in the Banos area (which is where I was scheduled to be in the next week or so, hearing about this has gotten my attention obviously).

Ed Note: Here is a geological map showing the faults, active and inactive volcanoes in Ecuador and other features that geologists would find interesting.

On going to google to get the map latitude longitude of Vilcabamba, marked it on the map as close as possible. (I don't know where exactly the retreat is with reference to the Vilcabamba coordinates, google wasn't that accurate) - the closest "anything" appears to be some fault zones as you can see, shown on the map. One can look at the change in the latitude longitude and draw a bee-line to the upper volcanoes to see where they are placed. Towards 0 on the equator, one can see the intensity of volcanoes increases dramatically.

Ash plume maps - 3rd and 4th Feb 2014

(see the volcanic institute website)

High altitude ash plume as show in the top map was the strongest on the 3rd (yesterday) traveling through SW Ecuador and out to sea.

On the 4th currently, the ash plume is lower and headed due EAST-ward (bottom map)

Activity maps can be seen on http://www.ssd.noaa.gov/VAAC/guag.html as well as review of archival events.

Ashflow and the ash cloud is dependent on winds aloft and of course volcanic activity.

We'll update the Forum as more information becomes available as long as the eruption continues.

Check back on the webcam image during the daytime to see current daylight activity.

I think, you should reconsider your settlement place again, there is no place on Earth as a Safest location.
Maybe we are going to lose all electricity, money system here(N America) but no one can be sure which catastrophic event comes first . Maybe major earth changes will take place way more earlier than that.
There was a good movie name "No Exit"

Hi Tangri - one can take a look at these current global activity reports put on the web by Smithsonian... for the week of Jan 22-28th 2014 you can see there is quite a lot of volcanic activity. Of all things the mainland US of A, and Africa are pretty calm when it comes to volcanism.

Photo taken from the 17H00TL OVT, February 5, 2014. The column goes towards the S-SE.

The seismic record associated with the surface manifestations has varied between periods of several hours with few seismic events followed by others with frequent explosions of small to moderate magnitudes and also the emergence of important bands of tremor (seismic vibration continues) that lasts about 15 minutes or more.

It is during these events that tremor similar to a locomotive (chug-chug) sound is heard and there is a greater output of incandescent material, the columns are taller and small pyroclastic flows occur occasionally. Also very vigorous jets loaded with ash up to 4 km above the crater (Fig. 3) are observed.

Bob (and others!), very many thanks for all the interesting updates.

Jeff, Christine and I have just returned from a long road trip through Southern Ecuador, venturing deep into the Amazonian rain forest. Not an speck of ash to be seen: everything was quite normal.

Ya, tirelessly updating Avalon on the 3 erupting volcanoes from the area of about zero and north wards latitude.

My associate just north of the Tungurahua volcano called me yesterday from the top of the mountain in the Park, reporting very hard breathing, and ash in that area. He is determined to continue working in that area as long as he can, going to the spots we discussed. Glad I am not in that area at 13,000 feet plus :) I bet down south is beautiful ! show us some pix :) much better than ugly volcano pix..

Special Official report number 5 from the Institute Geologica - ref: http://www.igepn.edu.ec/

Summary of the activity of the Tungurahua Volcano from 3 to February 6, 2014

On Saturday, February 1, 2014, the Tungurahua Volcano produced a major eruption in the generation of several pyroclastic flows on the flanks of the cone is pointed. These flows down through the north-western, western, southwestern and northern flank. There is also no confirmed evidence that pyroclastic flows down the south-eastern and eastern flank.

Ashfall February 2-5 affected provinces causing significant effects near the volcano and the city of Cuenca.

Starting on 03 February, the volcano has remained almost constant column emission of fine ash, water vapor and magmatic gases.

In most cases, these columns have reached about three miles above the crater and on Monday and Tuesday headed north causing ash falls in Ambato, Patate, Latacunga and parts of Quito.

On Wednesday and Thursday the column was directed to the southeast by the action of the prevailing winds.

The populations most affected by the fall of fine ash are Pondoa, Vazcún, and San Antonio Runtún and less involvement at Rio Verde and Rio Black to the East.

http://www.igepn.edu.ec/images/stories/Volcanicos/tung06022014-1.jpg

The seismic record associated with the surface manifestations has varied between periods of several hours with few seismic events followed by others with frequent explosions of small and moderate magnitudes and also the emergence of important bands of tremor (seismic vibration continues) lasting about 15 minutes or more.

It is during these events that tremor similar to a locomotive (chug-chug) sound is heard and there is a greater output of incandescent material, the columns are taller and small pyroclastic flows occur occasionally. Also very vigorous jets loaded with ash up to 4 km above the crater are observed.

(when you see these patterns of seismicity (below) in the attached seismic graphics in the posts, you will recognize that such is what they are describing above..)

http://www.igepn.edu.ec/images/stories/Volcanicos/tung06022014-2.jpg

The staff of the Geophysical Institute, both in Quito and its Tungurahua Volcano Observatory are continually working on the monitoring and evaluation of geophysical parameters of this eruptive period, and will continue to inform the authorities and the community about the further development of the activity of the volcano.

And later in the day, there was a slight increase in the smaller tremors, indicating a slight increase in lower pressure activity (surging effects). (see below) with a slight decrease in the larger outbursts.. as if there is a slight changing in direction of the internal magma flow, and a decrease in the gas content (causing the explosions).

The cyclic activity (peaks and quite periods) yesterday at showed that about 1300 local time, there was an increase in low level surging, but no major outbursts until about 1700 local.

The Tungurahua Volcano, called a Strato-Volcano (is a volcano that builds up with multiple layers of pyroclastic flow material, and lava, like layer cakes),

http://upload.wikimedia.org/wikipedia/commons/4/4f/Stratovolcano.jpg

and strato-volcanoes comprise the largest percentage (~60%) of the Earth's individual volcanoes and most are characterized by eruptions of Andesite and Dacite lava material.

These are lavas that are cooler and more viscous than basalt.

These more viscous lavas allow gas pressures to build up to high levels (they are effective "plugs" in the plumbing), therefore these volcanoes often suffer explosive eruptions.

These plugs popping, are the source of the peaks we see in the seismographs. (see post #33 above to see these in action)

Prior to the plugs forming, we see a SURGE in low level activity (see the seismic graphs above in post #33) while the molten magma moves around, forming in pockets, then in plugs, mixed with Sulfur Dioxide toxic gases.

These volcanoes are the most deadly worldwide, and should not be taken lightly.

Examples of strato volcanoes include Mt. St. Helens, Mt. Rainier, Pinatubo, Mt. Fuji, Merapi, Galeras, Cotopaxi, Tungurahua.

Strato volcanoes are usually about half-half lava and pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.

If you recall, the massive explosion at Pompeii, destroyed by Vesuvius in 79AD had immense pyroclastic flows. Herculaneum was also destroyed.

One should never ignore a Strato-Volcano

In Post #33 and post #34, compare the seismicity starting at about 1200, and one can "see" in the graphic the commonality of the magma flows remaining "liquid" and not forming explosive plugs. When the plug solidifies after a period of decreased movement, then gas builds, and an explosion happens.

Here are the two graphics side by side, yesterday and today:

What we are learning here, is what happens as warning signs in the strato-volcanoes..

I have another thread started on another StratoVolcano in Indonesia. The western side of the Ring of Fire, travels through Indonesia. These volcanoes ARE significant for world class events capable of damaging the environment, and crop production, creating a "nuclear winter" scenario.

I am paying attention to these strato-volcanoes. See the link in the Forum here: http://projectavalon.net/forum4/showthread.php?68464-Erupting-Volcano-of-Mount-Kelud-on-Java-island-Indonesia&p=797209&viewfull=1#post797209 to understand more on the RING OF FIRE volcanic belt (http://en.wikipedia.org/wiki/Ring_of_Fire).

15 Feb 14 Tungurahua volcano Ecuador - STABLE

No major explosions were seen today as far as when this was posted. However as we have seen in the last two days, starting about noon local, the magma movement starts to pick up. This may be indicative of a rise in magma with solar influx. Currently there are particle storms hitting the Earth from a Coronal Hole which is Earth facing.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021512.gif

This report will be updated when the graphic above completes for the day.

(note - to understand more on the potential phenomenon of the surge in magma and seismic activity, when the sun is overhead, please take a look at Mitch Battros's research about his theory that when solar storms light up and send particles to the Earth that the Earth has to absorb that amount of energy and deal with it.

If there is heating of the plates, more so than the normal friction induced by the plates subducting, or moving over each other there could be more slippage, earthquakes, and potential volcanoes lighting up.

Mitch's website is: http://earthchangesmedia.com/ )

ED note UPDATE: - as the sun passed through zenith and similarly as in the days before, the seismic rumbling of magma movement diminished. This periodic change is interesting and has been noted now. Maximum rumbling appears to be about 1 hour after zenith lasting for about 3-4 hours, potentially indicating that some time is needed for the solar particles to be absorbed and for a reaction to occur and then a slow diminishing (if cooling happens?).

16 February 14 - Tungurahua condition - STABLE

throughout the nite, there were small rumblings, until about midnite local time when there was a large explosion "boom" indicative of a solidified magma plug blowing. (see below)

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021600.gif

in this next seismic graphic, we can track throughout the day to see if there is a peaking of lower level seismic starting to happen near the noon-time window, for at least 3-4 hours, tracking solar particle influx. As seen below, it did in-fact happen once again, the buildup surging of lower level magma, and then an explosion "boom", between 7 and 8 am local time.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021612.gif

From the space weather prediction center, documenting some of the solar activity, and a prediction of lesser activity in the upcoming days:

"QUIETING SUNSPOT: After days of nonstop activity, big sunspot AR1974 is quieting. The sunspot's magnetic field appears to be losing some of its unstable complexity, prompting NOAA forecasters to downgrade the chance of an X-class flare today to only 5%."

Solar wind though, being emitted from the Coronal Hole (see below) is still predicted to be on path to Earth, hitting through the 18-19th Feb. The assumption would be while the particle influx is happening, there will be magmatic activity, correlating to when the Sun is at zenith.

Tungurahua volcano, Ecuador - condition - 17 Feb 14

Watching the seismic from yesterday, into the night and into the early morning, as the rumbling started to subside after the sun went down, there was a build-up just before 0500 AM local time. This event was a very long duration "surge" only seen when the volcano was erupting earlier in the month. (look at the graphics around the 7th)

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021700.gif

An expected explosion (which happened about 0600 AM local) was a release of a plug/gas buildup.

Given the magma circulation being what it has been, if solar activity remains constant, it seems if one sees a long period of very low, almost nil activity in the seismic, and a few large spikes appearing, the possibility for a major "clearing event" eruption may be possible.

Below we see the current seismicity. Again do note the TIMING of when activity starts to increase, which is when the sun starts to approach the zenith.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021712.gif

The solar coronal HOLE (a large band of dark in the image below at the TOP of the sun in the picture) is squarely pointed right at the earth and IS generating a particle stream. Based on the research observations of Mitch Battros (earthchangesmedia.com), when solar particles (in excess) are absorbed by the Earth, there is a tendency for earthquakes and volcanic activity.

This is correlating precisely with the rise and fall of seismicity in the Tungurahua volcano in Ecuador as we have seen in the last set of days that this has been being observed.

Tungurahua status - active, but stable

My associates who were traveling up at the 13,000 foot altitude range north of the Volcano have had to leave the area due to SO2 poisoning, cutting short their two week exploration of the mountains in this part of Ecuador. Visibility and SO2 and ash had been issues since the 5th. Even though the published graphics had not been showing "deadly" levels of the toxic SO2 gas, the reports from those on-site, at altitude, reported being affected, both from SO2 and the continuation of ash particles being stirred up by winds, and being put back into the atmosphere.

It seems then that during a volcanic ash-flow, or eruption where the ash is shot upwards into the atmosphere, the remaining "fallout" of the ashfall, unless it is washed away with rains, continues to be able to be circulated back into the atmosphere, to remain a lung/breathing problem. One of the associates is getting medical care for the issue.

Here is the recent SO2 map published, on the active volanoes only normal emissions from the volcanoes are being indicated. However during an "explosion" of the gas as indicated on the seismic charts, these explosions do not show up on the SO2 graphics as they are not sampling during when the gas eruptions happen. (The satellite moves overhead so it is not a continual real-time data monitor). Ground SO2 and sensors mounted elsewhere "at altitude" or on mountain tops where people visit, would be needed.. Ecuador does not apparently have such real-time sensors for SO2 placed in the region.. (only local volcanic seismic is real-time).

http://satepsanone.nesdis.noaa.gov/pub/OMI/OMISO2/Ecuador/Ecuador_OMI_SO2_20140217_1843.gif

This is the set of seismic to look at what happened throughout the night and into early morning - the second graphic will complete by the end of the afternoon, into evening, showing the seismicity of the Volcano.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021812.gif

There were some larger explosions, more so than the previous evening and morning. Starting about the same time as in the previous days, the lower level rumbling had increased, but not as much as when the Solar Coronal hole was directly facing the Earth. (see the solar coronal hole map below). We have been tracking on this hypothesis that the Earth will respond to solar particle influx with increase in earthquakes, and volcanic activity. Tungurahua has been ideal for monitoring with the very good real-time seismic graphics. Mitch Battros had first postulated that the solar-earth particle absorption heating concept is a valid effect that can be used to predict earthquake/volcanic activity.

Shortly after 0900 AM Local there was a starting of the rumbling once again, that tracks with the movement of the sun towards the zenith position.

Around 1030 AM Local there was a large sustained explosion, larger than usual. Then at about 1345 pm Local there was a similar large explosion of the same relative amplitude and timing profile.

If the period of time decreases between these explosions there is cause for concern as what would be similar to the events leading up this last major eruption.

http://spaceweather.com/images2014/18feb14/coronalhole_sdo_blank.jpg?PHPSESSID=2jrqs0ntusd21h7gti9bo0bbb5

Significant event noted

Just before 1900 hours local time, a significant explosion with long duration seismic rumble lit off - see the seismic graphic above.

19 Feb 14 Tungurahua volcanic update - stable during the night, unsettled during the daytime

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021900.gif

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014021912.gif

Above the rumbling was peaking as earlier in the week, tracking the solar particle stream influx, then the pattern changed later in the afternoon, altering the oscillation rhythms that had been previously occurring. Before 1900 hours local, numerous short rapid explosions (not too severe) started to happen, with continued low level surging rumbling.

This second peak could correspond to a geomagnetic storm happening on the 19th..

Finally by 2000 hours local seismic activity became strangely quiet. One should be cautious at this point and expect to see some periodic explosions, for the Volcano to "clear its throat". If those do not occur, there could be a buildup of gas deep in the volcano, with a plug that is being suppressed, pushing back on the magma. It is believed we should not think that this current volcanic episode is "over" just yet..

(check the seismic graphic updated through the night to watch for activity)

20 Feb 14 Tungurahua - stable with apparent solar activity tracking "surges" in seismic

The seismograph appears to be having unusual periods of "offset" happening during the solar activity period which has been noted over the last couple of days. (see below). There have not been major outbursts (which is unusual and should be watched for a couple of days). I may pull up some other seismographs of other ACTIVE volcanoes in Ecuador further north and south to look at the tracking information to see if there has been any movement north or south of the magma sources.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014022012.gif

Space Weather tracking is reporting:

"STORMY SPACE WEATHER: Space weather around Earth is stormy--and might get stormier in the days ahead. Our planet's magnetic field is reverberating from the second CME impact in as many days. According to NOAA forecasters, another CME could arrive late in the day on Feb. 20th followed by another on Feb. 22nd. For the most part, these CME impacts are minor and/or glancing. However, their combined effect is significant. A G1-class geomagnetic storm is now in progress so high-latitude sky watchers should remain alert for auroras."

http://spaceweather.com/images2014/20feb14/m3.jpg?PHPSESSID=dhlsaqibpakqj19c0i8nn5eet3

So instead of a Coronal Hole pointing to the earth CME events have been reverberating the magnetic fields of earth (and ionosphere), leading to Auroras further south.. the assumption then the odd "offsets" showing up in the seismograph's circuitry would be from the magnetic field "ringing".

Here is the general view showing the nil coronal hole activity.

Geophysical Institute, Ecuador issued a potential alert warning - for Tungurahua volcano

Special Report No. 9 Tungurahua Volcano
Update the eruptive activity of the volcano Tungurahua

As indicated in the Special Report No 8, the eruptive activity of the Tungurahua volcano in recent days has been characterized by the generation of moderate explosions, emission of ash moderate load that led to the fall of this material in the southwestern sector volcano until the 26th February and the generation of small pyroclastic flows that have fallen into the northern and northwestern flanks of the volcano over a distance of no more than 400 m below the crater rim.

There are no reports of surface activity during the 27th, nor the presence of ash around the volcano, but the volcano's seismic activity has increased significantly over the last day, quite possibly indicating the presence of fluid motion.

Additionally, since 15 February, the deformation monitoring network recorded inflation at the top of the volcano, which could indicate a construction material (gas and / or magma) is now building in this sector of the volcano. (such was indicated with Mt. St. Helens prior to the explosive blow-off of that cap)

This inflation could be related to seismic events recurring type LP (fluid motion) already mentioned.

Under these conditions a possible explosive reaction at the surface in the coming hours or days is not ruled out.

The staff of the Geophysical Institute and the Tungurahua Volcano Observatory keeps monitoring the volcano's activity and report any changes that was generated on the volcano.

Tungurahua 4 March 14 - seismic sensors went off line last nite and did not come back on until 0100 AM local time.

All activity on both seismic sensors has ceased (as well as with Reventador up north north east of Quito) - this is unusual as these volcanoes have been continually active for the last 4 years.

The Geological Institute had issued a special watch alert statement, special report #9, post 48 above - "since 15 February, the deformation monitoring network recorded inflation at the top of the volcano, which could indicate a construction material (gas and / or magma) is now building in this sector of the volcano." (sudden quiet is not necessarily a good thing as magma will cool and plug the vent(s).)

ED NOTE - Tungurahua also experienced a very large event shortly before 1600 local time today, as did the three other volcanoes we have been monitoring.

This is significant. - some of these volcanoes are many many miles away, up to 100 miles in one case, although similar timing for the "event" happened. This shows a tie-in in some way with the magma system.

There has been a discussion that possibly ECUADOR northern Andes chain is actually part of a massive supervolcano system that spans the volcanoes to the north border with Colombia, east into the rainforest, and South to Sangay/Tungurahua - the largest in South America, on this Eastern side of the "Pacific-originate" Ring of Fire. We may start a separate thread to investigate that possibility. There are many questions WHY so many volcanoes in such an area in Ecuador.

Tungurahua volcano tracked the event at CotoPaxi today at just before 1900 - 15 Mar 14 -

It also tracked the event at just after 0400 local time. Tracking BOTH events even though the two volcanoes are separated by many 10s of miles is VERY significant indicating a larger seismic magma related zone is probably feeding both these volcanoes. It has been been discussed that this "arc chain" tied into the Northern Andes could be part of a supervolcano.. Seeing this much simultaneous activity across the northern Andean volcanoes is extremely interesting..

Tungurahua volcano - Ecuador, seismic and volcanic report 24 March 14

The volcano is very quiet today, with very slight tracking with the events up north on the CotoPaxi volcano. It appeared that Reventador's massive purging that started about 0330 am local and continued till about 0630 relieved a lot of the magmatic pressures.

There are no large solar coronal holes pointing earthward, and therefore are not streaming particles that could heat up the earth's plates, facilitating eruptions. Whatever is triggering the events is unknown at this time, unless it is a delayed oscillation from the previous peaks in the previous weeks. One can review the graphics on the seismo-heliographs and see the event timing.

27th March 2014, 23:30

This is interesting to watch:)

The cyclic activity, and the tracking of the magma flow between the over 110 mile long volcanic arc chain is fascinating.. It's so "alive" and how it interacts with the rest of the "ring of fire" and the continental plates, the regional plates, and the solar and geomagnetic activity. Determining the patterns present, and prior to, when the bigger eruptions will happen, and watching the relief valve (Reventador) is interesting (to see it discharge the potential catastrophic flows elsewhere in the arc chain).

I believe this eastern section of the ring of fire (southernmost s. America, northward, thru Chile, Peru, Ecuador, Colombia, Pan America, Mexico, California, Oregon, Washington State, Vancouver, and up to Alaska) is very key to what happens within the surrounding regions. Ecuador gives us a great view from a well documented region of the Northern Andes.

Tungurahua - volcano Ecuador - seismic and volcanic activity graphs - 28 March 14

The volcano was quiet during the night, very quiet. During the morning there was a small "bump" and an event that tracked the one at CotoPaxi volcano 54 miles to the north at about 0906 am. The silence is ominous as it is out-of-character for the volcano. It is assumed that Reventador 110 miles to the North is acting as the "relief valve" of the magmatic pressures from this volcanic arc system in the Northern Andes. (see the Reventador thread for more information).

Solar activity:

There is a steadily increasing amount of particles being sent to the earth, but no large "spikey" events (high energy bursts that need to be absorbed and dealt with) at this time.

There was a coronal mass ejection (CME) associated with this event, but based on direction and speed, significant storming is NOT expected. There are several CMEs being modeled at this time (the one from this event and several others) and low-level geomagnetic storming is expected in the April 1st – 2nd timeframe as a result. That forecast will be refined as analysis continues." ref: http://www.swpc.noaa.gov/ - we should watch for any significant change in the seismic or volcanic eruptive patterns on the 1st - 2nd April 14 to see if any CME activity changes any output levels.

A substantial "pulse" event happened last nite about 0100 am.

The two small events (prior to 2000 last nite, and prior to 0800 tracked exactly with the CotoPaxi volcano 54 miles to the north - indicating a tied in magmatic/seismic system exists - in essence, the potential for a massive volcanic chain could erupt over hundreds of miles should a "supervolcano" event happen. There is no understanding exactly HOW such a thing could happen, so we cannot predict, and are looking for patterns of "simultaneous events" happening at distant volcanoes in the arc-chain.

NOTE - that has been no tracking or correlation to the Yellowstone Wyoming potential super-volcano as that volcano system is the result of a floating hot-spot, similar to the spot under Hawaii, and Iceland.. The South American volcanoes, up thru those in California, Oregon, Washington state, Vancouver Island, Alaska are all part of the eastern (Pacific's) Rim of Fire. This ring of fire monitoring provides useful data about events happening along the chain when the multiple plates discharge their energy into the "system". How that all happens is yet to be determined, and studying these events is important to find patterns and find triggers.

Gua Gua Pichincha - volcano Ecuador - Seismic and Volcanic Activity - 1 April 2014

There was a server outage until 2200 last nite, however after the connection was restored, it was noted that there was a small event about shortly before midnite, not a rock slide..and another small burp about 0630. Afterwards and into the morning between 0600 and 0900 there was a series of very small spiking happening, very brief short bursts, similar to the CotoPaxi volcano.

We are waiting on a potential CME reaching the earth from an event from Saturday (x-ray flare), which supposedly will glance, or hit starting about 11:30ish pm 1 April and continuing through the 2nd April.. If that happens, there may be increased activity, and we will note it one way or another..

The volcano is strangely very very silent.. generally when that happens when activity has been "high" either the volcano has emptied it's magma channels, or something has been plugged up. If plugged up the tilt-meters would show tilting when the cone and ground changes shape. The Geological Institute which provides these graphics is watching the tiltmeters and will report if there is substantial tilting on a report on their main page.

After yesterdays Chilean 8.2 quake, with the rocking and rolling, and changes in the magmatic flows, this volcano was quiet during the night and then some activity started during the morning hours. Shortly before 0800 local it looked like there was some small magmatic events followed by what could have been a 3 minute long sustained magmatic explosion.

The expected CME from Saturday's solar event still has not reached the earth, so we are watching to see if there will be any change in activity when the particles reach the earth.

http://correo.igepn.edu.ec/heli/heli/ARA2_SHZ_EC_--.2014040312.gif

The seismometers captured 4 sizable and long duration aftershocks.

At 2104 one can see the pre-quake event, the double bump fracturing before the big one appears at 2138 local time.

The total time lasted 26 minutes with 6-7 cycles per minute large ground sway oscillations starting at about 2200.

At 2320 the volcano lit off an explosion. And another small one about 0008 local time. There continued to be tracking with the Chilean aftershocks throughout the early morning hours, tracking CotoPaxi's seismometers.

Summary - the Chilean quake (and aftershocks) are taking their toll on the Ecuadorian volcano(s).. The magma flow, the activity patterns have changed to in some cases, cessation/stoppage, to in other cases, reactivation indicators are apparently showing up.

Report from the Geological Institute - http://www.igepn.edu.ec/

April 3, 2014

From the morning of Wednesday, April 2nd of this, there has been a slight increase in seismic and surface activity of the Tungurahua volcano.

This change in behavior is related to the registration of a large number of seismic events associated with the mobilization and pressurizing fluid into the volcano, with respect to the previous days. In addition, data from the monitoring system of deformation have identified that since March 20 a slight but steady inflation of the top of the volcano is recorded.

During the day yesterday, at 07:57 and 23:05 (local time), two small explosions considered were recorded. These events were accompanied by roaring and rolling incandescent blocks on the flanks of the volcano. Due to favorable weather conditions last night, it was observed that the explosion of 23:05 (local time) generated column emission of about 600 meters above the crater and incandescent blocks drop up to 600 meters under the same level. In the case of the explosion of 07:57 (local time), a fall of ash black color, same size and smaller than grains of sugar, in communities and Cotaló Chacauco reported.

According to the above, it can be concluded that registered during the April 2, explosions are the result of a new process of pressurization at the top of the cone and that is evidenced by the net deformation of the volcano.

Based on the behavior of the volcano eruption in previous episodes, it is possible that this activity will continue to increase in the coming days or is this a sudden change in a period of a few days to a few weeks.

Tungurahua - volcano Ecuador - ACTIVE ERUPTION 4/5 April 14

As seen in the seismic shortly before 1800 local time the prior bumps and explosions from yesterday and yesterdays' evening culminated with a massive release and eruption. This eruption is consistent with our observations and the Geological Institutes' observations that Tunguruhua was coming back "alive".

By studying the related seismic graphics from the previous days, the patterns or "re-wakening" can be noted. We are also looking at activity in the other volcanoes in this arc chain of Ecuador's northern Andes for any synchronous activity with this volcano (common magma plumbing ?).

The Chilean quakes and aftershocks of recent couple days as have been noted in the posts, have changed the patterns in the Northern Equadorian seismic and volcanic activity.

Here are yesterdays' late afternoon graphic followed by the late evening and into the early morning seismic:

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2014040512.gif

By the looks of the last seismic, the activity has subsided a bit with an eruption pulse rate of about 1 pulse per minute. Bursts are about 45 seconds to 55 seconds in duration.

From the Geological Institute, the official agency who monitors this volcano (and the others in Ecuador), the report says:

"A blast from 18:10 (local time) on 4 April, a constant tremor signal energy remains high, interspersed with explosions.

Associated with this activity was observed until approximately 20:00, time from which remains high cloudiness volcano sector, the expulsion of incandescent blocks rolled down the upper flanks of the volcano, and the presence of a column emission of gases and ash.

"In general, there have been howls of moderate intensity, except registered at 21:10 (local time) that caused the vibration of the structure of the Tungurahua Observatory (OVT) volcano, located 14 Km northwest of the volcano.

"Related explosion 18:10 (local time) have received reports of falling rubble (lapilli) of 1-3 cm in diameter in populations of Bilbao, Choglontus, Chacauco and Cusúa.

"With respect to the direction of the column associated with the explosion, emission can be determined based on satellite images that heads west, northeast and northwest.
Because the volcano remains at a level considered high and no evidence of behavior change, the Geophysical Institute recommends maintaining prevention measures in areas of influence of the Tungurahua volcano.

Geophysical Institute

23:00 (local time)

An earlier report was as follows:

"April 4 at 18:10 (local time), the monitoring network of the Geophysical Institute reported a loud explosion with a duration of 5 minutes generated pyroclastic flows that descended the streams of northwestern and northern flank of the volcano ( Vascún streams, Pyramid, etc.).

"The initial column reached 10 km above the level of the crater and its main direction was toward the southwest. Another pulse was recorded at 18:16 with a duration of 4 minutes with other possible generation of pyroclastic flows. From 18:24 one continuous emission tremor that lasts until the publication of this newsletter (19:00 local time) is recorded.

"So far, there are reports drop in Bilbao and Cusúa gravel and ash Píllaro. on this day five explosions were generated moderate size.
The staff of the Tungurahua Volcano Observatory (OVT) and the Geophysical Institute in Quito remains attentive to changes in the activity of the volcano. "

Tungurahua, volcano Ecuador - volcanic activity and seismic - STATUS ACTIVE ERUPTION - 6 April 14

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2014040612.gif

After a slight 2 hour break last nite about 2200 hours local, the volcano started back up with 10 minute long sustained eruptions, followed by a short pause of varied 3-6 minute intervals and then sustained activity. There have been periods of hardly any seismic activity, such as today after about 0704 local, and then an immediate movement of rock and then very active bursts 6 minutes later.. It is impossible to track against CotoPaxi, 54 miles north, although one can see increases in seismic swarms, and bumps while Tungurahua erupts. Reventador has slightly slowed down in the interval between eruptions, however the eruptive period has been reduced to 3-4 minutes per outburst.

http://www.igepn.edu.ec/images/stories/01tungu.jpg

Report from the Geological Institute:

"April 5, 2014
From about 23:00 (local time) of April 4, 2014, a decrease of energy of seismic and surface activity of the Tungurahua volcano was noted. However, still remains at a level considered as moderate to high. The activity is characterized by the generating an almost permanent tremor signal, interspersed with small explosions.

"At dawn, the expulsion of incandescent blocks hit the top of the sidewalls (Strombolian activity) in the morning and from a standing column of steam and gases emission was observed with low ash content of less than 1 km, observed height and moving in a direction to the West. Associated with this activity have been steady roar of moderate to low intensity."

Tungurahua, volcano Ecuador - ACTIVE ERUPTING - volcanic and seismic activity - 7 April 2014

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2014040712.gif

Eruption activity continues with a bit more output than Reventador 110 miles to the north - two strong emissive volcanoes in Ecuador are outputting smoke, SO2 (gas), ash and lava. The northern volcano has slightly diminished it's eruptive output spacing out peak emission and quiet periods, while Tungurahua has increased its output and diminished it's quiet periods. Predicting the rhythm at this point doesn't seem possible. Chile continues to have large "aftershocks" that could be contributing to the instability of the volcanoes in the Ring of Fire northwards.

The volcano has strong periods of activity, with calmer gaps, but such continued that pattern into the morning and afternoon. Both Reventador 110 miles to the north northeast and Tungurahua volcanoes are erupting in Ecuador. Tungurahua had been threatening for days, and had kicked off on the 4th April, shortly after the large Chilean quake and large aftershocks. The quake momentarily interrupted the Reventador's volcanic eruption pattern as well.

"Last night, from the Tungurahua Volcano Observatory (OVT) several photographic sequences of long exposure and thermal imaging sequences, in order to show the progress and extent of the flow were made; The results of analysis of the sequences seem to indicate that the flow was stopped around 23:30. It is estimated that at that time, the lower flow front was located at the approximate elevation of 3400 m and then its extension from the inner crater would be just under 3 km. "

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2014041812.gif

From yesterday 2100-0200 this morning, the volcano exhibited some periods of long sustained activity of higher intensity. Afterwards, the older patterns of puff puff puff started to resume, shorter periods of activity for 1 minute up to a minute and a half. It seems when periods of calm occur, the magma river starts to cool in the plumbing and when activity resumes it has to break through the build-up. Longer sustained activity happens during the release of the build-up, and then after the pressure is reduced, the surge/puff, surge/puff appears to happen.

When periods of sustained calm (minimal lava/ash) but when there continues to be rumbling, it is suspected that magma is building deep in the volcano. The Geological Institute is concerned about a potential for a large explosive eruption happening in the next week to two.

From the Geological Institute page:
"After analyzing deformation data, indications that continued to show increased inflationary patterns on the flanks of the volcano.

"High out-gassing rates are occurring; recent data shows high values greater than 1500 tons of SO2 per day. "

SO2 gas is toxic (Sulfur Dioxide). H2S gas (hydrogen sulfide) is possible as well. Water vapor is being noted in the steam clouds when the eruptions happen.

Volcanic Gases - what are they?

Tungurahua is reportedly putting over 1500 TONS of SO2 (Sulfur Dioxide) toxic gas into the atmosphere every day while this eruptive period (http://www.igepn.edu.ec/index.php)

Background:

At high pressures deep beneath the earth's surface, volcanic gases are dissolved in molten rock. But as magma rises toward the surface where the pressure is lower, gases held in the melt begin to form tiny bubbles. The increasing volume taken up by gas bubbles makes the magma less dense than the surrounding rock, which may allow the magma to continue its upward journey.

Closer to the surface, the bubbles increase in number and size so that the gas volume may exceed the melt volume in the magma, creating a magma foam.

The rapidly expanding gas bubbles of the foam can lead to explosive eruptions in which the melt is fragmented into pieces of volcanic rock, known as tephra. If the molten rock is not fragmented by explosive activity, a lava flow will be generated.

Together with the tephra and entrained air, volcanic gases can rise tens of kilometers into Earth's atmosphere during large explosive eruptions. Once airborne, the prevailing winds may blow the eruption cloud hundreds to thousands of kilometers from a volcano.

The gases spread from an erupting vent primarily as acid aerosols (tiny acid droplets), compounds attached to tephra particles, and microscopic salt particles.

The most abundant gas typically released into the atmosphere from volcanic systems is water vapor (H2O), followed by carbon dioxide (CO2) and sulfur dioxide (SO2).

Volcanoes also release smaller amounts of others gases, including hydrogen sulfide (H2S), hydrogen (H2), carbon monoxide (CO), hydrogen chloride (HCL), hydrogen fluoride (HF), and helium (He).

The volcanic gases that pose the greatest potential hazard to people, animals, agriculture, and property are sulfur dioxide, carbon dioxide, and hydrogen fluoride. Locally, sulfur dioxide gas can lead to acid rain and air pollution downwind from a volcano.

Globally, large explosive eruptions that inject a tremendous volume of sulfur aerosols into the stratosphere can lead to lower surface temperatures and promote depletion of the Earth's ozone layer. Because carbon dioxide gas is heavier than air, the gas may flow into in low-lying areas and collect in the soil.

The concentration of carbon dioxide gas in these areas can be lethal to people, animals, and vegetation.

A few historic eruptions have released sufficient fluorine-compounds to deform or kill animals that grazed on vegetation coated with volcanic ash; fluorine compounds tend to become concentrated on fine-grained ash particles, which can be ingested by animals.

Sulfur dioxide (SO2)

The effects of SO2 on people and the environment vary widely depending on (1) the amount of gas a volcano emits into the atmosphere; (2) whether the gas is injected into the troposphere or stratosphere; and (3) the regional or global wind and weather pattern that disperses the gas.

Sulfur dioxide (SO2) is a colorless gas with a pungent odor that irritates skin and the tissues and mucous membranes of the eyes, nose, and throat.

Sulfur dioxide chiefly affects upper respiratory tract and bronchi.

The World Health Organization recommends a concentration of no greater than 0.5 ppm over 24 hours for maximum exposure. A concentration of 6-12 ppm can cause immediate irritation of the nose and throat; 20 ppm can cause eye irritation; 10,000 ppm will irritate moist skin within minutes.

Emission rates of SO2 from an active volcano range from <20 tonnes/day to >10 million tonnes/day according to the style of volcanic activity and type and volume of magma involved.

For example, the large explosive eruption of Mount Pinatubo on 15 June 1991 expelled 3-5 km3 of dacite magma and injected about 20 million metric tons of SO2 into the stratosphere. The sulfur aerosols resulted in a 0.5-0.6°C cooling of the Earth's surface in the Northern Hemisphere.

The sulfate aerosols also accelerated chemical reactions that, together with the increased stratospheric chlorine levels from human-made chlorofluorocarbon (CFC) pollution, destroyed ozone and led to some of the lowest ozone levels ever observed in the atmosphere.

At Kilauea Volcano (Hawaii), the recent effusive eruption of about 0.0005 km3/day (500,000 m3) of basalt magma releases about 2,000 tonnes of SO2 into the lower troposphere. Downwind from the vent, acid rain and air pollution is a persistent health problem when the volcano is erupting.

SO2 causes air pollution Volcanic smog

Tunguraha UPDATE - statement by the Geophysical Institute 24 April 14

The surface activity of the Tungurahua volcano in the past two weeks shows a fluctuating trend, which is evident in the change between the low level of activity observed in the early morning of 20 April and sporadic episodes of emission of water vapor that little energy MSNC not exceeded 500 in a westerly direction preferentially recorded from this date and the three separated by intervals of about 5 minutes observed on 22 April in the afternoon broadcasts;

These explosions were characterized by moderate ash content (Fig. 1), being little energy, not being accompanied by acoustic energy (sound) and no greater heights to 2 km above the summit.

However, the seismic signals recorded persistent activity marked by numerous seismic events of long period (LP, 70 -100 events / day) to indicate a significant fluid movement within the volcano.

Additionally, deformation data inflation denote a clear trend in the northwestern flanks of the cone, especially in the upper part. The degassing rate ranges from 1000 to 1500 tons / day, rated as moderate value.

http://www.igepn.edu.ec/images/stories/Volcanicos/tung24042014-1.jpg

In the morning yesterday (02H00TL) came up with a volcano-tectonic earthquake (VT), the same as it was felt and reported by observers who are near the volcano. The event was a magnitude of 3.0 on the Richter scale and was located on the south-eastern volcano flank to 11 km below the crater.

http://www.igepn.edu.ec/images/stories/Volcanicos/tung24042014-2.png

A few minutes after the quake, a prolonged emission occurred, which was accompanied by roars of low intensity incandescent bearing blocks (Fig. 2) was recorded. After this event the volcano remained fairly quiet, with the registration of only two small explosions. (see the previous days posts)

http://www.igepn.edu.ec/images/stories/Volcanicos/tung24042014-3.jpg

Due to the oscillatory activity of the volcano and the aforementioned issues, it is estimated that major explosive events could occur in the coming days to weeks. Technicians Geophysical Institute, both in Quito and Tungurahua Volcano Observatory (OVT), are aware of changes having volcano and are constantly evaluating monitoring data and observation, to communicate promptly to the authorities and community at risk.

Tungurahua Ecuador Volcanon - activity 11 May 14

Starting about noon yesterday there was a long duration seismic rumble of about 10 minutes which started small, built up and then diminished. Interspersed were small explosive events, which were preceded by larger events (about 1 minute for each).

At 1900 another similar type of event started, but was about 4X larger and continued for about an hour, a similar pattern (reminded me of tide rising and falling), or this was a very slow wave event of a large magmatic or deep stress release with a lot of large movement. There was no sudden abrupt shift, quake appearing.

About an hour later, another similar type of surge lasting about 30 minutes occurred, followed by smaller similar "moments", continuing at a lower level, with smaller surges, and smaller durations until about 2230 hours. A few small explosions happened later, with periods of gradual increasing background rumble, showing what was looking like a small harmonic tremor, repeating patterns and is continuing at a very low level as of the time of this posting. The patterns are like a train running continually over railroad tracks, with small spikes as the "wheels" click as they travel over the rails.. This is one LONG train :)

Tungurahua - volcano Ecuador - weekly activity report 24 May 14

Seismic activity, (rumbling) was present at the start of the 20th period, with some peaking on the 21st as was noted with the other volcanoes of Ecuador that are monitored. After the period of brief activity on the 21st, vibrations, diminished, with brief swarms of small but sharp pulses. Activity started picking up with increasing frequency of microswarms (fracturing events) towards the 24th. The massive explosion predicted by the Geological Institute never happened, so they must be perplexed as to what is going on with the magmatic channels of the northern Andes volcanic arc chain. What I have noticed is the volcanic day and a half oscillation slow wave present in the Reventador volcano north about 100 miles of Tungurahua, and increasing activity in the previously relatively quiet CotoPaxi Volcano, and increasing strong oscillation periods happening at G. Pichincha volcano near the city of Quito.

If there is cone building, tilting, elevation changes in the region, that can indicate magma-gas buildup and there can be a massive explosive event, when the solidified cap frees itself. Volcanoes are dangerous and complacency with a quiet volcano is not a wise thing.. Stay aware stay tuned.

Tungurahua Ecuador Volcano - activity status 27 May 14

Continual regular seismic spike activity is occurring, although nor large eruptive pulses have been noted in the last two days as of the time of this posting. This observation of no major predicted eruption of the volcano is a bit of a contradiction of the Geological Institute's predictions having traced magmatic activity and deep seismic traces of volcanic activity - the prediction changed after the 8.2m Chilean quake of 1 April, 2014, leading to apparent rechanneling of the existing magma rivers in the Arc Chain (of the northern Andes), reactivating normally previously quiet volcanoes as far up as Colombia/Ecuador border.

Increasing periods of continual seismic rumbling, regular and steady, interspersed with seismic short brief spikes and magmatic activity. This could be indicative of an impending "blow", however, harmonic resonance in the seismic signatures have not been seen in these graphics. Possibly the Geological Institute has satellite data on cone rise, and tilt indications. A [possible tilt was occurring today about 1700 hours local time.

The eruption is latest after months of activity around Tunguarahua volcano

Rose Troup Buchanan (http://www.independent.co.uk/biography/rose-troup-buchanan) , Monday 01 September 2014

An Ecuadorean volcano is spewing ash five miles into the air, closely monitored by experts, after an eruption this weekend.

Ash from the Tunguarahua volcano, whose name means ‘Throat of Fire’ in the local Quechua language, was blown five miles, 28,000 ft, into the sky and drifted west.

It was the latest eruption from the volcano after a period of calm.

Tunguarahua volcano erupted on 29 July, 4 August and then again on 19 August.

Homes nearby have felt the strength of the eruptions, with the blast causing windows and roofs to vibrate.

Over the weekend the volcano started spewing small pyroclastic flows, a fast-moving current of hot gas and rock which can reach speeds of 450mph and temperatures of about 1,000 C.

In pictures: The Tungurahua volcano erupts in Ecuador: 1 of 8

http://www.independent.co.uk/incoming/article9703714.ece/alternates/w1024/volcano-ecuador-4.jpg

The volcano has been classified as active since 1999, with frequent powerful ash explosions producing ash plumes and dangerous pyroclastic flows part of the population around the base has been evacuated.

It is located in the Andes, 87 miles south of the capital Quito.

It's a another blow for the aviation industry which is already reacting to the Icelandic volcano (http://www.independent.co.uk/news/world/europe/iceland-volcano-red-aviation-alert-after-third-eruption-9702050.html), which last night downgraded its aviation warning back to orange from red, and an eruption in Papua New Guinea disrupting air travel (http://www.independent.co.uk/travel/news-and-advice/air-travel-disrupted-by-fresh-volcano-threats-in-iceland-and-papua-new-guinea-9700353.html).

I'm posting this seismic chart to point out particularly interesting "explosive events" coming from Tungurahua volcano.

Note just after about 0400 particularly strong graphic images, "pulses". These pulses (I count 6 of them), are defining part of the acoustic structure, PLUS part of the magma plumbing system of the volcano. Like hearing the "echo's" in a classic small town church, where every whisper resounds and reverberates, if one analyses the data, one can back reconstruct what's the inside structure..

The pulses diminished - with an exception of a large explosive event about 2230 local last nite.

Early morning hours were marked with small explosive events offset by a few hours. During the daytime hours this morning, explosions resumed to about a 1 hour period in-between.

The surface activity of the volcano has been characterized since November 10 by a continuous emission with a moderate load of fine gray ash. Emissions have reached up to 3.5 km CNS and were headed north, west and northwest. As a result of this issuance activity ash falls they were recorded in the sectors of Manzano, Choglontus, Bilbao, Mocha, Quero and Cotaló. In addition, since yesterday afternoon was observed output incandescent blocks from the crater to the north, northwest and east; these blocks came to about 500 m below the summit without reaching populated areas. The explosive rumbling has been constant in the last few hours, causing vibration of windows in the vicinity of the volcano sectors.

Strong activity (eruption) continues, and has been non-stop since the 11th - periods of heavy activity has been saturating (peaking out) the seismic detectors monitoring the Volcano. Strong eruptive pulses started on the 9th and then diminished slightly at the time, but activity was picking back up on the 10th. The magma chamber/plumbing appeared to respond to the Chilean earthquakes and aftershocks, apparently free-ing up the plumbing to allow for flow to proceed out of the cone. Regionally, plate activity (seismic events) appears to be triggering volcanic activity as far north as Mexico.

An announcement by the US Embassy in Ecuador today:

U.S. Mission Ecuador

Security Message for U.S. Citizens

Tungurahua Volcano Alert Level Raised to Orange

November 18, 2015

The U.S. Embassy in Quito informs U.S. citizens throughout Ecuador that on November 17, 2015, the Ecuadorian Government raised the Tungurahua Volcano alert level to orange due to an increase in volcanic activity, primarily elevated levels of ash emission. According to the Ecuadorian Government, an orange alert means one must prepare for an adverse volcanic event. Tungurahua is located near the popular tourist destination of Baños, in Tungurahua Province, central Ecuador, about 180 kilometers south of Quito.

We strongly advise U.S. citizens residing in or planning travel to areas affected by Tungurahua to familiarize themselves with government evacuation plans in the event of a major eruption or further upgrade in the volcano activity alert level. Additionally, you should review your personal safety plans and ensure you have adequate emergency supplies, including face masks, food, and water.

The particular "double pulse" pattern on the Tungurahua has taken on a more abrupt explosive characteristic.

Why monitor Ecuador's volcanoes?

They have a very good sensor system and available data. Such is hardly available elsewhere on the Ring of Fire.

Monitoring the Ecuadorian volcanoes gives a good insight into the volcanic "Ring of Fire totally up along the pacific coast thru US Alaska and over in to Japan and southward from there."

It is critical to see if anything is happening there which reflects through the ring of fire. Even the Cascadia Range on the US west coast is affected..

Another strong regional earthquake which evoked subsequent volcanic action in Tungurahua.. See below. At about 2245.. After this seismic event very strong explosions and eruptive activity started in bursts at the volcano. (see below)

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2015120200.gif

this may clear or not depending on the magma channel contents.

CotoPaxi managed to survive the seismic hit (earthquake) without going into eruptive activity, but it was noted earlier, that a period of small volcanic tremor started up and lasted for an hour. tremor events usually mean magma movement in the plumbing system, and depending on the blockage in the plumbing, either it will melt gracefully and slowly or will radically explode.

Low level seismic tremor has started up and has been continuous on Tungurahua since about 1200 local time today. Outside of some large singular explosive events within the plumbing system of Tungurahua, it has been relatively quite over the last few days.. VT usually is a sign that magma is moving in the plumbing of the volcano, and could subside, or build up to an eruptive series of events. Spikey events have been a precursor to eruption as well as the VT.. Keeping an eye on this..

Cotopaxi in the north has had a few very strong seismic pulses recently, and spikey events but generally has calmed back down.. There were a series of regional earthquakes which showed up on both volcano's seismometers over the last day.. Possibly that could have triggered Tungurahua's plumbing to start moving magma around.

It is interesting on the west side of the ring of fire (this particular channel is being watched as it affects many in the regions it touches), a large seismic quake (and aftershocks) happened. Volcanoes up and down the "ring" could reverberate, and become active, or faults elsewhere could slip, along the "ring"..

Bob

3rd March 2016, 13:22

Tungurahua eruption continues.

Looking at the seismographic of CotoPaxi, apparently that volcano's monitors did pick up the activity on the other side of the world, on the southwest extent of the Ring of Fire..

There was a reverberation noted in that "channel". There is a connection along the "ring of fire" with other volcanoes across the world, that which happens elsewhere along the channel is reflected throughout the channel. "We are all connected.." The concern next would be to see what happens in the Chilean area for seismic activity.. and to see if volcanic activity changes in the Ecuadorian volcanoes.

Below is the seismograph for CotoPaxi - note the activity starting around 0100 am local time, this is indicative of what could be a period of magmatic activity, magma moving in channels deep within the earth. The spikey activity afterwards, around 0220 am local could be indicative of rocks fracturing, melting. Slow wave oscillation at 0253 am local time is indicative of volcanic activity, but no current eruption activity is shown.

Eruptive activity continues to show oscillation (periods of stronger and weaker emission). Large seismic quakes are happening within the region to the northwest of Tungurahua, (West of CotoPaxi), which could be allowing for magma channels to open up flows to existing reliefs (volcanoes).

7th March 2016, 14:58

Noticing the seismic eruption pattern for Tungurahua is showing larger periods of diminished activity. Usually what happens it appears, is the magma starts to solidify, pressure builds, and an explosion and strong seismic event happens. If a large magma dome within the earth builds, fills, and then pressure appears on it, an explosion could be much larger. These smaller events provide for pressure releases.

CotoPaxi continues to show deep activity, and there are periods of increasing seismic tremor. Solar activity is "odd" with a reverse polarity incoming particle wave, creating a lot of auroras deep south spreading into Europe, the US, across Asia where Auroras do not happen often. See forum post here: http://projectavalon.net/forum4/showthread.php?71579-Geometry------in-Solar-Coronal-Holes&p=1051556&viewfull=1#post1051556

This extra energy has to go somewhere, and historically weather events, volcanic events, earthquakes happen. Animals and people act differently.

Eruption continues with lulls of up to an hour; during the eruption periods activity peaks with explosions which are about a minute in length.. Then 2 hours of strong activity, then an hour of sporadic activity.

Solar activity is showing a reversed polarity particle bombardment than earth normally experiences from the sun. Auroras are showing more RED displays. Green is relatively normal for proton assault, red shows up when electron (reversed polarity) is appearing. Red is seen a lot over Antarctica, Green is shown over the Arctic.

Eruptive activity has dramatically diminished as can be seen in the second seismographic (above) starting about 1500 pm local time. The pulses are large seismic events, explosions.

Below is what it looks like today. When these emissions have finally fully stopped, the eruptive period could be called over.. Or what could be being seen currently is merely a 'lull' in activity. It would be good to watch the other volcanoes (i.e. CotoPaxi), for increase in activity. Magma can move to different "underground plumbing channels" when the existing magma paths alter (melting, fault shifting..)

The Geophysical institute presents this update for Tungurahua - be aware that there may be eruptions coming soon from the Volcano:

Summary
The Tungurahua volcano has maintained a low surface activity since its last eruption (26 / 02-15 / 03/2016 ) . Seismic and degassing activity has remained at baseline levels, except for a small swarm of seismic events Long Period (LP's) occurred between 1 and 20 May associated with fluid movements. However, observations of deformation show a magmatic intrusion from the end of the last eruption.

In the last 8 years the volcano Tungurahua has repeatedly shown these periods of apparent calm and reactivations after they have presented clear premonitory signs short-term (hours to days) in only 20% of the time.

Based on that and the rest time that has had the volcano so far (79 days), it is estimated that a reactivation of Tungurahua medium term (weeks to months) is probable and two potential eruptive scenarios are defined:

1) a reactivation gradually, of strombolian style, with ash fall mainly corresponding to the most likely scenario;
2) a rapid revival of Vulcan style, with a large eruption column and pyroclastic flows.

These scenarios are detailed at the end of this document.

The aim of this report is timely to alert the authorities and the population of the possibility of an eruption of Tungurahua in the medium term (weeks to months).

An eruptive pattern of large amounts of rock fractures started to appear with the volcano Tungurahua shortly after 0100 am local time and peaked slightly after 0200 am local for about 25 minutes.

The larger pulses are "incidents", brief bursts of activity. This marks the longest sustained activity since early March this year.

For 5 hours continuous today (current), spikey activity (rock breakage) has been being seen by the seismographic monitoring the volcano.

Briefly at 1230 and 1300 there was a brief increase in activity, which diminished rapidly to a stream of rock breaking activity (hot magma can cause rocks to break, as can pressure buildup).

At about 1400-1600 hours local time spikey activity increased to what looks like 2X to 3X the background rate which was happening during the 1200-1300 time window.

Increasing rock fracturing activity can mean the "pipes" are being filled, although I didn't notice any strong slow-wave seismic activity (as is being seen in CotoPaxi up north). It could be the pipe is already filled and expanding in waves. That matches the prediction of the Geophysical Institute saying when it breaks through it may not be extremely catastrophic but more of an ash/gas emission with moderate pyroclastic flow.

However, if a strong pulse happens, there could be a strong eruption event. It depends on how the release happens, is it going to be gradual, with the "seals" being broken (the rock layer cap which had previously solidified since early March (this year). Tungurahua is noted for strong double pulse explosions, historically saying that pressure events release abruptly, resulting in "cannon-like" explosions.. and can be spectacular and hazardous at the same time. We're watching this as the Geophysical Institute closely.

The spikey blast appeared to increase in size at Tungurahua at about 2000 hours local yesterday, lasting for about an hour.

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016061400.gif

Tungurahua's signature "double pulse" was starting to appear, but was not very pronounced at this time. Still have not seen any well defined slow-wave (indicating magna movement in the pipes below and within the volcano). Double pulse showed up in the morning around 0940 am local.

Shortly before 0800 am local time, a seismic event was recorded which lasted for about 2 minutes. It was very low in amplitude.

Early patterns of eruptive activity are starting to appear with some regularity - this merely may be a symptom of magma movement within the 'plumbing' system. Seismic activity (low level sustained), plus "melt" signature rock bursts (10 second, there-a-bouts) with regularity is appearing. Tungurahu's signature "double-burst" patterns are being seen in the rock break patterns.

Looking at CotoPaxi's seismic activity, this volcano's seismographics are not showing similar patterns, thereby Tungurahua's signatures are localized. Keep an eye on this.

Brief update - have been watching the seismographics continually since the last post - everything is going 'relatively' quiet.

Except for a brief now and then 'pulse', or a regional seismic event being recorded (read 'earthquake') by the volcano's seismographs.

We're still following and will show noteworthy events..

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016080512.gif

11:01 am a brief small event with Tungurahua, preceded by very small rock fracture spikes appearing.

Bob

7th August 2016, 17:11

Tungurahua was getting a little bit active during the night and into early morning hours - even again, after a period of relative "calm" activity can perk up at any time.. Seeing rock breaking pulses prior to activity appears to be a good way to watch for any forthcoming events..

the event at about 1043/4 am local time lasted almost a minute - that was a noted change in the pulse pattern, which normally would have subsided by sun-up.

Bob

10th August 2016, 04:07

Evening, early morning, and late day - small rock fractures continue, and then followed by a larger double pulse seismic event of a little greater than a sustained minute of time event -

there is activity but no strong eruption pattern appearing such as large slow wave and more frequent larger seismic events (like a rapid series of pulses similar to the 1615 event shown above) - - scroll up to post 202 to see what a danger sequence would look like..

Bob

6th September 2016, 17:07

After a month of mostly calm, Tungurahua experienced a period of strong rock breakage, without showing slow-wave (strong magma) patterns. CotoPaxi volcano has been showing small brief slow-wave patterns.

Some well defined seismic pulses are happening today on the Tungurahua volcano:

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016091312.gif

Such was preceded by small rock-fracture events, and a characteristic double-pulse (for this volcano) appeared. The frequency was not consistent, one period being a two hour offset, the other being less than an hour. Potentially then there could be more magma build-up and some larger explosive events. We'll see how this looks throughout the night.

Today we saw an increase of VERY strong off the chart spikey activity and then BOOM a massive earthquake happened in Ecuador (as seen on both volcano's seismographics).. Such earthquake activity can trigger eruptions or the eruptions can evoke seismic slips (earthquakes) elsewhere.

Keep an eye on Tungurahua - The earthquake was closer to CotoPaxi than Tungurahua btw..

Early in the morning about 45 minutes of an eruption happened at the volcano. There was no warning, such as slow-wave, or strong pulse or double-pulse like events prior. Afterwards there was about 15 minutes of strong rock breakage spikes showing up. That diminished to calm when suddenly there were two very large impulses about 0700 and 0701. Worth keeping an eye on this morning.

It appears that Tungurahua has woken up again and is in an eruption cycle. If it increases or decreases we shall see. During the late night, a 6 minute low level sustained event about 2313 local time was followed by the signature "double pulse" events that Tungurahua has been noted to present.

Notice from the Geophysical Institute, Ecuador - re: Tungurahua's awakening

Interpretation

Volcanic rise of land (inflationary trend), indicating magmatic activity below.

In the last 8 years of activity Tungurahua volcano has had 15 similar quiet periods to the current period with low seismic activity, deformation inflationary trend, and surface activity characterized by low energy fumaroles.

Mostly these quiet periods were followed by small eruptions (Volcanic Explosivity Index IEV 0-1 with principal phenomenon ash falls) and sometimes by larger eruptions (IEV 2 pyroclastic flows). It is important to note that the vast majority (80%) of these eruptions had no premonitory signs of recovery in the short term (hours to days).

The actual deformation of the volcano is evidence of magmatic intrusion (movement of magma from a deeper reservoir) has been observed on many occasions before the eruptions of Tungurahua.

The low outgassing could indicate a blockage of the duct that prevents the free passage of magmatic gases. Given that the current quiet period had exceeded six months (185 days) and the sharp increase in seismic activity (LP since 12/09, from 16/09 tremor, and the swarm of LP 18/09) is It estimates that a (large eruption) in the short term (next few days to weeks) is possible.

Eruptive scenarios
Based on the results obtained from volcanic monitoring and the recent history of reactivations of Tungurahua two eruptive scenarios that could occur in the short term (next few days to weeks) is proposed:

1) Reactivation fast. During this stage of Vulcan style at the beginning of the eruptive phase or after a few days, it could produce a rapid opening of the duct with moderate explosions at large (eg. In May 2010, July 2013, April 2014). This scenario could be a large eruption column (up to 10 km above the crater) and pyroclastic flows that could descend the gorges to reach the foot of the volcano.

The falls of ash and rubble associated with this type of high eruptive column are more likely to affect areas farther from the volcano with more variable directions due to the variability of the wind direction at this point. Ballistic missiles (blocks and volcanic bombs) associated with explosions could reach a distance of 5 km from the crater.

In this scenario small lava flows could decline by the Northwest flank with a range of less than 4 km. side lahars could be generated due to the remobilization of eruptive material by rain and could cut the road Baños-Penipe. Depending on the amount of material accumulated in the streams and the intensity / duration of rain these lahars could be small to moderate.

This is the most likely scenario eruptive due to the absence of emissions of gas, which would indicate a closed conduit.

2) gradual reactivation. During this stage Strombolian style, which can last from several weeks to a few months, we could see small to moderate explosions, lava fountains and continue columns of ash less than 6 km above the crater (eg. April-May 2011 , March 2013, April 2015).

The main phenomenon is the ash falls, moderate to strong, which primarily affect the west of the volcano (unless a change in wind direction is observed).

Ballistic missiles (blocks and volcanic bombs) and small pyroclastic flows could reach a distance of 2.5 km from the crater. Small secondary lahars could be due to the remobilization of eruptive material by rain and could block the road Baños-Penipe.

It is important to note that volcanic eruptions are of an unpredictable nature and the activity of the volcano can also return to normal without eruption.

These settings can be changed according to changes in the activity of the volcano and analysis of data from the instrumental and visual monitoring. The IGEPN maintains constant vigilance in the center Terras (Quito) and Tungurahua Volcano Observatory.

The double pulses are still present, plus very small rock breakage patterns - in Post #227 above, the Geophysical Institute was warning of a potential for "rapid" relief of the magma with an explosive release (scenario 1) as being likely, with no strong warnings showing up on the seismiographic recorders. What is being noted is the double pulse pattern, explosive "releases" (not too large currently), and numerous very low level rock fractures. That could very well indicate that there is a "frozen plug" in place in the magmatic plumbing system. It could be assumed if there is a strong regional seismic quake, that the impulse may shake enough of the plumbing system to allow for a pressure relief to happen (eruption).

Yes -- this is being discussed in the media in Ecuador. In lay terms, like shaking a champagne bottle and then having the cork fly out under pressure. :)

Swarm activity is showing up today with Tungurahua. The seismic network has been down in Ecuador for the last 4 days, preventing viewing of geological activity with the volcano. This particular group of swarm activity appears to be due to rock breakage with magmatic heating from below (seeing slight slow wave magma movement patterns in between the pulses now and then).

Today later this afternoon, a brief period of eruptive activity happened. The geological institute has been waiting for a larger set of eruptions, which have not happened, yet.

http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016102412.gif

swams of rock fracture events have also been happening at the CotoPaxi volcano, although no large eruption has happened there recently. During the period of increased activity warning(s) from the geological institute, where Tungurahua was being watched, activity at CotoPaxi picked up.. There is an increase in solar particle activity from a brief CME and solar particle storm from an earthfacing coronal hole starting to move more squarely aligned with earth. Historically solar activity has been synonymous with increases in volcanic and earthquake activity. http://spaceweather.com/

Oct. 25-26 Earth enters a stream of high-speed solar wind flowing from a coronal hole on the sun. Analysts say storm levels could reach category G2,
