View Full Version : CotoPaxi Volcano - Ecuador seismic status
Cotopaxi Volcano now showing seismic swarms - 5 Mar 2014 - this volcano should be monitored for activity considering its location, and
from: http://www.britannica.com/EBchecked/topic/139756/Cotopaxi - Britannica's historical on Cotopaxi
"Cotopaxi, volcanic peak, in the Cordillera Central of the Andes, central Ecuador. Rising to 19,347 feet (5,897 m), it is the world’s highest continuously active volcano.
"Cotopaxi has an almost perfectly symmetrical cone, interrupted only by one minor cone—the Cabeza del Inca (“Inca’s Head”).
"The mountain has a long record of violent eruption and has seldom remained quiescent for more than 15 years. The terrain around the mountain’s base has many times been devastated by earthquakes or been buried in pumice and ash blown out of the crater.
"Lava that boils constantly in its crater emits plumes of steam. The mountain itself is built up of alternating flows of dark-coloured trachytic lava and falls of lighter-coloured ash.
"The crater at the top is 2,300 feet (700 m) in diameter from north to south and 1,650 feet (500 m) from east to west. Its depth is 1,200 feet (366 m). The base of the volcano stands on open mountain grassland, but the whole upper part of the mountain is covered with permanent snow."
Following where the magma flow under Ecuador's northern mountains may be moving, after Tungurahua abruptly stopped obvious eruption activity a few days ago, Reventador north northeast of Quito started an increase of activity. That activity continued for a few days, and then volcanic seismic activity picked up at GuaGua Pichincha to the west a bit, but very close to Quito. That diminished and activity started to the southeast of there, with seismic swarms of Cotopaxi.

"Cotopaxi is a stratovolcano in the Andes Mountains, located about 50 km (31 mi) south of Quito, Ecuador, South America.
"It is the second highest summit in the country, reaching a height of 5,897 m (19,347 ft) and is one of the highest active volcanoes in the world. "
http://upload.wikimedia.org/wikipedia/commons/2/20/Cotopaxi_volcano_2008-06-27T1322.jpg
"Since 1738, Cotopaxi has erupted more than 50 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano."

Eruption Danger
Future Cotopaxi eruptions pose a high risk to the local population, their settlements and fields.
The main danger of a huge eruption of Cotopaxi would be the flow of ice from its glacier. If there were to be a very large explosion, it would destroy most of the settlements within the valley in the suburban area of Quito (with a population of more than 2,000,000).
Another city which would be in great danger is Latacunga which is located in the south valley and was destroyed in the 18th century by volcanic activity.
Cotopaxi is about midway between Tungurahua and Reventador volcanoes, both of which have been erupting in February, 2014.
CotoPaxi volcano Ecuador located about 31 miles south of Quito continues to show bumps and mini-swarms of seismic activity - 6 March 2014

CotoPaxi volcano Ecuador remained stable during the night time period, with slight seismic bumps and small swarms - 7 March 14
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014030700.gif
Activity started to pick up with some small eruption-like activity as the solar zenith approached.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014030712.gif
Spike times were between 1 and 4 seconds, some were longer duration. These spike swarms were starting to present as a few 2 minute long events.
Coronal hole activity on the Sun is sending particles towards the earth.

The strength of some of the events is a little bit larger and of longer duration than previous days.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014030812.gif
Through the morning we saw up to a 7 minute seismic event, most likely a small eruption. Larger "bumps" were as long as about a minute in length.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014030900.gif
About 2115 local time, there was a substantial 2 minute event which resembled an eruption pulse.

Some 1 minute long events have resembled the earlier February Tungurahua seismic events prior to eruption. That does not necessarily mean that there is any eruption possibility, only that the events are resembling other volcanic activity from a volcano further south. Monitor the Geologic site in Ecuador for any warnings or notices.

small events lasting from 1 minute - 3 minutes were seen, with 30 second spikes of higher intensity.
Post 7 above apparently is showing increased activity corresponding to the storm spike from the x-ray flare that happened on the 11th.
Looks like definitely an "event" occurred shortly before 1600 hrs local today.

CotoPaxi 17 March 14 - seismic report
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014031700.gif
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014031712.gif
SIGNIFICANT - The two large events at shortly after midnite and about 20 minutes later tracked almost exactly with the events at Tungurahua volcano 56 miles to the south. This shows a directly tied in magma system, or a minimum of a potential supervolcano-like eruption (depending on the amount of magma which can void during a massive eruption. There are no solid indications that such and eruption can or will happen, the volcanic prediction science is evolving, so being able to record and monitor these events, and find significant tracking is essential in understanding these mechanisms)

The EVENT at about 1050AM local time at CotoPaxi tracked the event in the Tunguhura volcano about 56 miles south
The EVENT at about 0805AM local time at CotoPaxi also tracked the event in the Tunguhura volcano .
The events during the previous nite, about 1945 at CotoPaxi tracked the event in the Tunguhura volcano as well.
** this is significant indicating a simultaneous feed system for these volcanoes that are separated by quite some distance.
Here are the two Tunguhura heliograph charts to compare with the above:

CotoPaxi - Ecuador volcanic-seismic activity report 24 March 14
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032400.gif
Activity started with the calming down at Reventador's massive event sequence shortly after 0630.. As if the magma moved from the Reventador channel and moved into the CotoPaxi-Tungurahua channel.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032412.gif
Although there was slight correlation (minimal signal on the graphics) with Tungurahua, south of CotoPaxi, there was some activity, but Tungurahu for the most part was very quiet, the brunt of the volcanic activity happening up at Reventador.

CotoPaxi - Ecuador - Seismic and Volcanic activity report 25 March 2014
Shortly before 0500 this morning local time CotoPaxi woke up coughing with a sustained 8 minute event followed by at least a 1/2 hour of sporatic events.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032500.gif
Events continues on and off throughout the morning about 1 through 1 1/2 minutes long with rock slide movement indicated as well with what looked like tracking of the Tungurahua volcano further south.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032512.gif
I will post here the Tungurahua volcanic graphics so you can see the tracking sychronicity between the two volcanoes separated by 56 miles apart. That continues to show that there is a common magma system, in essence the makings of a "super-volcano" system exists potentially in this region.

http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032700.gif
Last nite shortly before 2200 local time for about 2 hours the volcano had an increasing magmatic rumble which the surge started to subside about 0000 midnite. HOWEVER, shortly after 0230 in the morning, there was a rather large single event, then another smaller event at about 0524 that lasted for about 2 - 3 minutes (peaking for about a minute).. As the clock got closer to 0600 there was another event of between a half minute to a minute, with associated rock slides. At about 0603 local a larger 2-3 minute event occurred.
During the rest of the day up till about 1300 there were small swarms and spikes, a couple of medium scale events near 1100 am. After 1300 a sustained 5 minute low level event chain occurred.
Then close to 1330 a 4 minute long rapid spike chain/event series swarm occurred. At about 1440 a very interesting view of a bubble building up, then "popping" was shown graphically. It reminded me of the volcano blowing smoke rings in the graphic appearance.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014032712.gif
All in all, the volcano is active, and unsettled. The patterns at 1440 haven't previously been reported on, so that is significant.

Continual brief very small events, with some larger bumps and slides throughout the nite and morning. A slightly larger event occurred a few minutes before 0800 am local time.

The two small events (prior to 2000 last nite, and prior to 0800 tracked exactly with the Tungurahua volcano 54 miles to the south - 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.
CotoPaxi - 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 2345 pm, not a rock slide.. Afterwards and into the morning between 0700 and 0800 there was a series of spiking happening, very brief short bursts, similar to the GuaGua Pichincha volcano by Quito.
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..

CotoPaxi - volcano Ecuador - seismic and volcanic activity - 2 April 14
Since the Chilean 8.2 quake, the Ecuadorian arc volcanic chain in the northern Andes has been experiencing unusual activity, with normal patterns having changed. Watching the quake for about 6 minutes, plus an hour of slow rocking of the ground for another HOUR was unusual to see. It was like watching ocean waves. (see previous post to view that phenomenon).
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2014040212.gif
There was a substantial event shortly after 1106 am local time which was also seen on the Tungurahua volcano's seismometers.
Seismic Network and Server was OFF-LINE intermittently today - 3 April 2014 1300 local time
There has been a concern about increased activity, changed activity when the CME from last Saturday hits the earth. BUT...
The so called "Glancing Blows" from the CME's of the other days have been reported as MISSING the Earth..
"CMEs MISS EARTH: NOAA forecasters have downgraded the chance of geomagnetic storms on April 3rd to only 1%. This follows a storm warning on April 2nd when a group of CMEs were expected to sideswipe Earth's magnetic field. However, all of the CMEs appear to have missed our planet. "

There are no earth facing Coronal Holes, (no particle emitted from such).

Planetary K-index
Now: Kp= 1 quiet
24-hr max: Kp= 2 quiet
Seismic activity monitoring is back on-line.. Very interesting graphics.
The seismometers captured 4 sizable and long duration aftershocks, which on a couple rocked the CotoPaxi volcano substantially. The speed of the slow frequency oscillation increased over the first main 8.2 quake the other day to about 7 cycles per minute; is something loosening up?
At 2104 one can see the pre-quake event, the double bump fracturing before the big one lets go at 2129 local time. The main event lasted 11 minutes with 4 cycles per minute large ground sway oscillations. These large 4 cycle per minute waves continued for 6 minutes, then the amplitude of the oscillation dropped a bit, and the frequency changed to 7 cycles per minute for a duration of 12 minutes then another small aftershock that lasted for a minute and a half..
4 more minutes of 7 cycles per minute ground sway oscillation was noted then another "bump" which looked like a local fracture at CotoPaxi volcano itself.. gradually for the next 28 minutes the ground sway rocking (increased to about 8 cycles per minute) and decreased in amplitude..
Finally at 2250 the CotoPaxi location in Ecuador stopped rocking and rolling..
However...
at 0031 there was a strong rock slide event at the Volcano, which didn't appear to contain any ground sway rocking from a distant quake. This event lasted for 9 minutes, followed by at 0058 another local combination of magmatic plus rock slide.
at 0325 there was a substantial event, a double bump lasting up to 2 minutes in duration.
at 0429 there was a harmonic like chug chug reminiscent of the Tungurahua volcano to the south by Banos.. This lasted for about 3 minutes..
In the morning, starting about 1103 AM, there started to build what appears to be a melting of ice and water/steam resulting in a small explosion at 1109. For a little over an hour a very high frequency "sizzle" was noted, reminiscent of steam leaving from water having entered a magma pocket (at 1109).
At 1724 there was a sizeable bump but no indication afterwards of any water/steam activity.
The amount of spike events looked about the same as previous days..
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.

About 2044 pm last nite CotoPaxi's seismometers recorded another aftershock from the Chilean quake on the 1st.
The rest of the evening and morning were characterized with the "normal" spike patterns and small swarm bursts out of the volcano. No eruptions were seen in the data.
CotoPaxi - volcano Ecuador - seismic and volcanic activity - 4/5 April 2014
The volcano was showing signs of microseismic swarms starting about 1600 hours local time, which continued for about 2 hours. The microswarms continued to drop until about midnite. About 0030 the was a sharp spike followed by a 4 minute event (possibly a slide, fracture movement).
Shortly after 0630 am on the 5th, swarm activity started to increase.
The microswarm activity continued to increase in amplitude until some sizeable explosive events were noted shortly before 1300 local time and again (but slightly smaller) a double burst at 1307 and 1309 pm local time.
This is significant that the volcanoes, Reventador, CotoPaxi and Tungurahua are all now experiencing increased activity, and two actively erupting.

Bobd, is this something to worry about? See Dr. Paul LaViolette's question.

This is not a good sign. Like earthquakes, coordinated global volcanic activity could be another indicator of an impending superwave. I am not a volcanologist to know how significant this is in terms of statistical probability. It would be good to compare this statistically with the history of volcanic eruptions.

Seven Volcanoes In Six Different Countries All Start Erupting Within Hours Of Each OtherA new island has appeared in the Pacific. A submarine eruption just off Nishino-Shima Island Japan has erupted for the first time in 40 years. The Japanese Navy noticed the explosions as boiling lava met sea water giving rise to plumes of steam and ash.
Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. A steam and ash cloud rose two miles into the sky and the grumbling of the mountain could be heard in towns a few miles away.
In Guatemala the ‘Fire Mountain’ belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. The explosions and shock waves occurring in the volcano can be felt by residents over 6 miles away. Doors and windows are reported to be rattling, but there has been no damage so far.
In Vanuatu the Yasur volcano is giving some cause for concern. Although the explosions are quite weak the continuous ash that is coming from the mountain is starting to build up on farming land.
Over to Italy, Mount Etna is putting on quite a display. The current eruption started a few days ago and has been getting stronger as time moves on. A massive eruption lit up the sky and disturbed residents yesterday. The ash cloud was high enough to see flights canceled. The lava flow was the biggest in years, and the town of Zafferana which lay in its path saw some damage. Lava diverters were put into place, and most of the town escaped unscathed.
I would say yes Wind. Although, I cannot say that I am convinced of his "superwave" theory.
We all have been watching the sun for solar activity.. tracking backwards and analyzing the seismic records for patterns, synchronous patterns, and solar activity (and particle fields, geomagnetic activity) would show if any additional energy is coming in. If one isn't seeing external energy coming in, and there are no unusual geomagnetic activity patterns appearing (they have to be widespread, and consistent) what is inducing simultaneous eruption? Is it a coincidence?
We have seen increasing activity with the 4 volcanoes being looked at in the threads, and there have been times of the day where such activity has been increasing, generally when the sun is overhead and when the sun is opposite on the other side of the earth. These events and activity can be seen on the seismic sensor maps and the dates activity started.
Below is some background data..
http://vulcan.wr.usgs.gov/Glossary/PlateTectonics/description_plate_tectonics.html - More than half of the world's active volcanoes above sea level encircle the Pacific Ocean to form the circum-Pacific "Ring of Fire."
The "Ring" provides excellent examples of "plate-boundary" volcanoes, including Mount St. Helens. ...
Located in the middle of the Pacific Plate, the volcanoes of the Hawaiian Island chain are among the largest on Earth. The volcanoes stretch 2,500 kilometers across the north Pacific Ocean and become progressively older to the northwest. Formed initially above a relatively stationary "hot spot" in the Earth's interior, each volcano was rafted away from the hot spot as the Pacific Plate moves northwestward at about 9 centimeters per year. The island of Hawaii consists of the youngest volcanoes in the chain and is currently located over the hot spot.
Most volcanoes are products of lithosphere-plate motions. The "ring of fire" around the Pacific represents one type of this volcanism. The chains of volcanoes in the island arcs (such as the Aleutian Islands) and continental margins (such as the Andes) around much of the ocean form above undersliding oceanic plates. The main volcanic axis is typically about 125 kilometers (80 miles) above the inclined zone of earthquakes that marks the descent of the lithosphere plate into the deep mantle ... so processes related to the descent and to that depth must control the melting of the magmas. T
he melts that arrive at the surface, to erupt in volcanoes, have been profoundly modified by reactions with the mantle and crustal rocks through which they have risen. Lavas formed in this setting have distinctive compositions and systematic variations that relate directly to their height above the subducting plate. These characteristics permit us to recognize rocks formed in similar settings in the geologic past and to estimate the depths to the long-dead seismic zones above which they formed. Where, in ancient terrains, the volcanic rocks have been eroded away, we now see granites and other rocks which crystallized slowly within the crust from similar magmas.
The high volcanoes of the Cascade Range in Oregon and Washington -- Mount Hood and Mount Rainier, for example -- form a short chain of this type, vigorously active until not many thousand years ago but now showing only infrequent activity. The decline in volcanism reflects a plate-boundary change now underway to the west: there was until recently rapid subduction of a small Pacific plate beneath northern California, Oregon, and Washington, but the pattern is presently changing; the San Andreas Fault system is now breaking across the small plate. ...
ubduction-zone volcanoes like Mount St. Helens (in Washington State) and Mount Pinatubo (Luzon, Philippines), are called composite cones and typically erupt with explosive force, because the magma is too stiff to allow easy escape of volcanic gases. As a consequence, tremendous internal pressures mount as the trapped gases expand during ascent, before the pent-up pressure is suddenly released in a violent eruption.
Such an explosive process can be compared to putting your thumb over an opened bottle of a carbonated drink, shaking it vigorously, and then quickly removing the thumb. The shaking action separates the gases from the liquid to form bubbles, increasing the internal pressure. Quick release of the thumb allows the gases and liquid to gush out with explosive speed and force.
In 1991, two volcanoes on the western edge of the Philippine Plate produced major eruptions.
Iceland, where the Mid-Atlantic Ridge is exposed on land, is a different story. It is easy to see many Icelandic volcanoes erupt non-explosively from fissure vents, in similar fashion to typical Hawaiian eruptions; others, like Hekla Volcano, erupt explosively. (After Hekla's catastrophic eruption in 1104, it was thought in the Christian world to be the "Mouth to Hell.") The voluminous, but mostly non-explosive, eruption at Lakagígar (Laki), Iceland, in 1783, resulted in one of the world's worst volcanic disasters.
About 9,000 people -- almost 20 percent of the country's population at the time -- died of starvation after the eruption, because their livestock had perished from grazing on grass contaminated by fluorine-rich gases emitted during this eight month-long eruption.
A few hotspots are thought to exist below the North American Plate. Perhaps the best known is the hotspot presumed to exist under the continental crust in the region of Yellowstone National Park in northwestern Wyoming. Here are several calderas (large craters formed by the ground collapse accompanying explosive volcanism) that were produced by three gigantic eruptions during the past two million years, the most recent of which occurred about 600,000 years ago. Ash deposits from these powerful eruptions have been mapped as far away as Iowa, Missouri, Texas, and even northern Mexico. The thermal energy of the presumed Yellowstone hotspot fuels more than 10,000 hot pools and springs, geysers (like Old Faithful), and bubbling mudpots (pools of boiling mud). A large body of magma, capped by a hydrothermal system (a zone of pressurized steam and hot water), still exists beneath the caldera. Recent surveys demonstrate that parts of the Yellowstone region rise and fall by as much as 1 cm each year, indicating the area is still geologically restless. However, these measurable ground movements, which most likely reflect hydrothermal pressure changes, do not necessarily signal renewed volcanic activity in the area.

about 0200 am there was a significant explosive event with the volcano, followed by small spikes until before 0800 where there was another small explosion. There are double pulse explosions when such occurs.

There was a rather large burst event shortly after 0530 in the morning, followed with a day of harmonic tremors, repeated long duration microswarms, and numerous small events. The double burst signature (which appears to be consistent with this volcano) appeared numerous times over the last 24 hour period. When the volcano is quiet, it is VERY quiet.. Which could be that "frozen" magma plugs are starting to thaw, when activity picks up. The volcano should be watched closely to see if anything escalates or if the pattern substantially changes.

CotoPaxi Ecuador Volcano 5 May 14 activity report
Since about 1300 local time yesterday, the volcano was continuing to have a substantial event 2-4 times per hour. This lasted until 1600 hours, picking up after 1900 hours (two events), and shortly after 2300 hours a strong impulsive event for a little over a minute. 5 minutes after midnight a sharp deep spike quake occurred. Afterwards there were continuing sharp abrupt quakes one per hour until about 0400 local, where there was a period of calm for 2 hours.
0530 was marked with an impulse of 1/2 a minute in duration. After 0630 a strong continual seismic shaking was noted lasting 3 minutes followed by aftershocks of diminishing intensity.
Shortly after 0830 a series of building microswarms, and harmonic tremors up to an hour long have been appearing. These are punctuated with periods of deep spikey abrupt quake events, and small magmatic pulses. The frequencies in the harmonic tremors are both high frequency and low frequency, including sweeps.

CotoPaxi - Ecuador - Volcano - activity 11 May 14
Starting yesterday about noon, the strong seismic events of long duration started, preceded by a period of regular small quakes (spikes) of about 3 per minute. A strong 12 minute long seismic event was noted starting about 1204 local time. This instability continued for at least an hour before major similar activity started back up about 1800 hours. During this window numerous continuous small quake spike were occurring.

Such instability continued (showing up as high noise in the seismic spectrum), until about 0400, where the events changed into abrupt sharp minute to minute and a half events.
Numerous continual small quakes, spikes were occurring from then onwards till the time of this post. A similar to the events of 1200 yesterday (solar zenith) was starting to appear as shown in the graphic.

This hole is straddling the sun's equator so the solar wind stream emerging from it will intersect Earth's orbit. ETA: May 16-17.
(I am not comfortable with this configuration)
This equatorial coronal hole is spewing a narrow stream of solar wind into space.
This is a potentially dangerous situation..

CotoPaxi Volcano Ecuador - activity - 14 May 14
Periods of harmonic resonance continues throughout the day. I counted 9 significant events, averaging 1 minute each with slow wave seismic activity, also at least one event containing harmonic resonance and fast wave oscillation. Numerous sharp quakes at least 18 were noted. At least 5 double pulse small magmatic events were noted.
Yesterday's solar coronal hole has closed, but the particle stream from it is still headed to earth, expected to reach between the 16-17th window.

CotoPaxi - ACTIVITY - Volcano - Ecuador - weekly report 24 May 14
The volcano appears to be continuing its path along increasing activity, although this could be a regional trend for the alteration of the magma channels since the April 1, 2014 massive 8.2 Chilean quake. As seen below, the 21st was the day of interesting increasing activity as appeared in the other active volcanoes of Ecuador.
Although about 1500 23 May a strong oscillation and pulsation started, indicating activity was appearing. These pulses consisted of the strong double pulse that is characteristic of this volcano.
The previous morning of the 22nd was marked with very strong continual seismic activity at least for an hour in duration, close to 1400 hours local time.
This volcano may be coming alive again and caution should be noted to stay aware of local notices.

The morning of the 24 was marked with repeated 2 1/2 minute long magmatic events, albeit smaller than a full eruption scale. Seismic activity continues with the corresponding double pulse signature of this volcano. The evening showed numerous small sharp seismic shocks, a few large abrupt shocks, followed by a series of 2 thru 2 1/2 minute long seismic shakes. Close to 0200 was an abrupt magmatic pulse. An hour later after the larger magmatic pulse was followed by a singular sharp seismic spike. Afterwhich there was a period of calming, until about 0630 where there was another sharp abrupt seismic pulse with sustained rumbling.
Shortly before 0800 there was another strong sharp seismic pulse, and there are periods of sustained low level harmonic tremor. The low level tremor continues as of the time of this post.

Activity on the 3rd was high, with long duration sustained seismic rumbles, sharp spikes and tremors. Some harmonic tremor was indicated. Today the 4th activity for the most part is relatively calm, however there are periods of 4-15 minutes in duration seismic low level rumble since about 0600 am local time (and has been gradually and continually building). This could show up as eruptive events, outgasing, or continual seismic swarms.

Magmatic event activity continues as seen above with the large pulses.
Cotopaxi volcano a year later - showing increased activity
The seismic activity of the volcano, as well as the emission of sulfur dioxide continues to have abnormal levels.
Note - that signals showing tremors recorded since June 4, have not shown up earlier in the volcano, since 1986, when the seismic instrument monitoring began.
Based on the seen tremor pattern, three scenarios are proposed (see graphic at the bottom of the post):
1. A further increase the activity. The monitored parameters continue to rise in the coming days or weeks with more evidence (felt earthquakes, gas boom continues and strong, strong sulfur smell, noise, increase flow in streams by falling muddy water). In this scenario phreatic explosions may occur in the crater.
2. A decay current activity. Just like what happened between 2001 to 2002, 2005 and 2009, we may soon start start to see parameters monitored down into the 'grassroots levels' throughout the coming weeks or months. However, it is possible that occasionally the volcano can produce small phreatic explosions inside the crater.
3. That an eruptive process starts. That is, the magma reaches the surface leading to an eruption. This scenario is now less likely, in view of the characteristics of the monitored parameters.
When scenarios 1 and 2 are the most likely - We will continue to evaluate behavior of the volcano in the coming days and weeks.
The Geophysical Institute of the National Polytechnic School is continuously monitoring changes in activity in the volcano and will promptly report any changes.
Any visitors or climbers are especially warned: "caution" in the area of the crater, to the possible occurrence of explosions, which throw blocks or very energetic emissions of steam and volcanic gases, which can be harmful to health.

Surface observations
As of June 10 it was observed a pulsating gas emission of a low energy level at the crater, from pre-existing vents on the volcano.
These reports were also confirmed by the staff of Refugio. The Cotopaxi National Park staff has reported an increase of water flow in some streams NE flank of the volcano.
Both long-period seismic tremor are showing up, as they relate to the vibration of fluids inside the volcano. Those tremor signals, are continuing. (see below)
SO2 flow
The emission of SO2 in recent days continues with greater than 2500 t / d values, representing an increase over baseline for the Cotopaxi (less than 500 tons / day). The prevailing wind direction was westward.

Fascinating, global activity ramped lately, Dutchsinse puts out regular reports, which include earthquake predictions, and 'in-depth' observations which make absolute sense.
Slightly less continual tremor with more active "events" happening for the 22nd June
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015062200.gif
Note the regular event pattern starting to appear. Catestrophic events tend to happen when there is a build-up, due to a trapped pocket "freezing" (solidifying) and gas builds up and cannot escape.
Less tremor and less of the events happening -

Cotopaxi volcano puffed out a bunch of ash.
QUITO, Ecuador — A 2-mile-high (5-kilometer-high) plume of ash shot out of the Cotopaxi volcano near Ecuador's capital Friday in two pre-dawn blasts, coating highways, homes and cars with a fine gray powder.
Government scientists said the 5,987-meter (19,600-foot) snow-capped volcano doesn't seem to be on the verge of a major eruption.
Authorities nevertheless restricted access to the park that surrounds Cotopaxi and suspended ascents of the peak, which is popular with mountaineers.
Patricio Ramon of Ecuador's geophysics institute told Teleamazonas TV that the explosions were small phreatic eruptions, which occur when molten rock, or magma, meets water and produces a violent steam release.
"The situation merits the population staying informed about what's happening with the volcano," said Ramon.
The volcano is 30 miles (50 kilometers) from Quito. It began showing renewed activity in April. Its last major eruption was in 1877.
Cotopaxi is considered one of the world's most dangerous volcanoes due to a glacial cover that makes it prone to fast-moving volcanic rock and mud flows, or lahares, and its proximity to a heavily populated area.

"We declare a state of emergency due to the unusual activity of Mount Cotopaxi," Correa said during his weekly Saturday address. "God willing, everything will go well and the volcano will not erupt."
The move allows the president to immediately mobilize security forces throughout the country and lets the government block publication of information related to Cotopaxi.
The state of emergency may not exceed 60 days.
Correa said that about 400 people have been voluntarily relocated to shelters after the explosions and expulsion of ash surprised nearby residents on Friday.
The Environment Ministry closed the Cotopaxi National Park as a precaution.
At 0500 AM tremor activity started up again as shown in the graphic:

Strong rumbling persists -
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015081612.gif
Seismicity: In the last 24 hours 107 events of long period (LP), 3 hybrid (HB), 25 events volcano tectonic (VT), 25 episodes of tremor emission, 2 explosions and pyroclastic flow down one flank were counted in the Western region of the volcano.
Gases: From 07h00 to 17h00 yesterday through DOAS instruments have registered an average of 8340 tons / day of SO2, from 44 valid measures and a maximum of 20,000 tons associated with the explosion of 10h25 LocalTime. The OMI instrument reported a total mass of 16,400 tons of SO2. These values are consistent with the explosive and emissiive activity recorded yesterday.
Observations, and ash emissions: an increase in the amplitude of the seismic signals from the 07h15 local weather and about 40 minutes is noted along this tremor episode of falling pyroclastic material followed by an emission of ash and gases. Working groups from the Geophysical Institute reported the presence of ash in the lower area of Cotopaxi. This area remains within the area for evacuation because of the winds.
Rain: A rain gauge located in the north-eastern flank collected 35 mm of rain in the volcano area.
Note: Today IG three teams worked in the area of Cotopaxi.
These teams conducted the collection and recognition of ash deposits and the maintenance and repair of monitoring stations that were affected by the ash.
Additionally a flyby was conducted in which were found no lahars, confirming what was observed with the land based instrumentation.

means it is prone to fast-moving mud flows Small eruptions have already shot ash more
than 5km (three miles) into the sky, spreading fine grey powder over as far as the
capital 50km (30 miles) to the north.Authorities have restricted access to the park that
surrounds the volcano and barred mountaineers from climbing the snow-capped peak.
Cotopaxi last had a major eruption in 1877.

Ecuador Suspending Some Constitutional Rights, Banning Media
From Publishing Unauthorized Information As Volcano Erupts
By David Icke on 17th August 2015
http://www.davidicke.com/wp-content/uploads/2015/08/ecuador-volcano.jpg
ecuador-volcano‘Ecuador’s government declared a nationwide state of
emergency Saturday to prepare for a possible major eruption of a
snow-capped volcano south of the nation’s capital, Quito.
The decree, which includes suspending some constitutional rights and
banning media from publishing unauthorized information, will allow the
government to redirect budgeted funds for a possible emergency and
prevent rumors from inciting panic, President Rafael Correa said in his
weekly television and radio address to the nation. The measures will
last up to 60 days.’
Cotopaxi, which rises about 19,350 feet (5,900 meters) above sea level,
began erupting on Aug. 14. A series of explosions since have sent ash
clouds as high as 5 kilometers (3.1 miles) into the air and led to
preventative evacuations in towns south of Quito.
Cotopaxi is about 50 kilometers (31 miles) south of Quito and last erupted
between 1877 and 1880, according to the South American nation’s
Geophysical Institute, known as IGEPN. About 2.2 million people live in
the greater Quito metropolitan area, according to the 2010 census.
The volcano will probably continue to erupt with larger explosions in the
short- to mid-term term as magma rises toward the volcano’s surface,
IGEPN said in a report Friday.
Authorities are preparing for possible flooding and mudslides in towns
surrounding the volcano, including Quito’s suburbs, if glaciers covering
the peak are melted during an eruption. Much of the city’s urban expansion
in recent decades has filled potential flood plains, increasing risks.
The geophysical institute reported new pyrochlastic flows, including rock
and ash, down the volcano’s west flank around 8 a.m. local time Saturday.
No injuries or damages have been reported.

Ecuador Declares State of Emergency Over Cotopaxi Volcanic Activity...
s-Ln25aGPJI
Published on 17 Aug 2015
President of Ecuador Rafael Correa has declared a state of emergency due to
increasing activity at the Cotopaxi volcano, known as one of the world's most
dangerous. Several hundred people have been evacuated from nearby villages as
the volcano began erupting on Friday. Small eruptions caused hot ash to fly more
than three miles into the sky, even reaching the capital city of Quito about 30 miles
north. Sunday's declaration of a state of emergency gives officials more flexibility in
using government funds in response to the volcano's activity.

Cotopaxi was relatively quiet last nite with one large explosive event at about 0300 local time. It was preceded by 2 hours of spikey activity, and seismic tremor. After the event small tremor lasted for about an hour and then subsided, with spikey activity once again.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015081900.gif
This morning about 0800 am local time, tremor resumed for about 1/2 hour

A larger event about 1717 local time preceded a major decrease in activity. That can happen if the magma chamber has a large chunk of rock fall in, then it "bursts" out, creating a pulse. Never-the-less, 'things' shifted, and with this shift the seismic pattern switched to a "puffing pattern", reminiscent of an old style steam locomotive..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015082500.gif
Between midnite and shortly after 2am local there was hardly any activity - then seismic activity resumed, and was pulsing once again. The spacing between the pulses was decreasing to a lower periodicity, (slower cycle between the radical changes).
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015082512.gif
Strong seismic emission started again, indicating internal activity within the volcano about 0530 local time, and is continuing with a cyclic periodicity of about 1 hour between large high amplitude activity and activity reduced by about 1/4 amplitude.

Cotopaxi last nite continued to be very active - this morning a slight drop back to the "steam locomotive-like" puffing, the resumption of strong continual seismic tremor (and ash cloud).

By 1500 local time the seismic tremor reduced a bit with some abrupt spiking activity - which is indicative of "things breaking" and/or falling. If there is continual activity, this pattern would appear - a pulse/explosion, followed by strong seismic activity, and then a 1 hour oscillation period of strong and weaker cycles of seismic tremor - we shall see what happens in the next hours.

Small seismic pulses continue to emit around the CotoPaxi volcano -
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015091600.gif
Decreased seismic energy and the size of the ash emissions. Possibility of new pulses of activity.
Summary:
Since the September 5 (report N.- 14) there has been a decrease in the levels of seismic energy and the size and ash content of the columns emission of Cotopaxi volcano.
The occurrence of an earthquake of magnitude 3.4 to 4.5 km under the crater of the volcano and the progressive increase in small particle sized material in volcanic ash, which has as its source the fragmentation of magma in the magma chambers. This decrease in activity may be temporary and could be followed by new pulses eruptive activity.
Activity start and peak and diminishment cycle:
http://www.igepn.edu.ec/images/portal/noticias/volcanes/cotopaxi20150910-1.jpg
The last 10 days on the right side of the peak have shown continual diminishment of activity in seismic output, as well as ash and gas outflow.
The occurrence of an earthquake of magnitude 3.4 on the crater and observed changes in the proportion of small particle sized material in the ash suggests that magma continues moving slowly inside the volcano. As observed, it is considered that the decline in activity in recent days may be temporary and one can not rule out the occurrence of new pulses of eruptive activity.

The Chilean Event is at the bottom of the top graphic; this seismic monitor at CotoPaxi (Ecuador) is showing the large 8.3 Chilean earthquake. It can be observed the primary event, and the slow waves afterwards, the "rocking" and the secondary quake event as well.

After shocks (the long duration patterns such as at 23:36 pm for 4 minutes) from the Chilean Event continue to be recorded up in Ecuador, at CotoPaxi's volcano. The CotoPaxi volcano continues to output "pulses" (as projected by the Volcano Institute) such as at 03:37 am. Pulses result from pressure build-up and "releases" explosively occurring. This volcano is not asleep (and nor is the region on the Ring of Fire). The double pulse pattern is a representative signature of the Ecuadorian eruptions.

The continual spikes are creating concern for those in the volcanic Institute - they have published this scenario projection:
3 Scenarios:
The following scenarios for the next days to weeks arise as possible; these contemplate the occurrence of increases of volume of magma from the magma chamber into the reservoir:
a) slowly come back with several major pulses of magma into the reservoir, spaced apart by a time of several weeks or months. In this case, several pulses of eruptive activity materialize several times, so this eruption process continues for months (type Tungurahua March 2013). The thickness of accumulated ash are important in the prevailing wind directions. This eruptive phase can produce bursts of moderate size with ballistic drops bombs that reach up to 5 km from the crater with small pyroclastic flows (type Tungurahua July 2013). Additionally they can form lahars (volcanic mudflows and debris) generated by secondary volcanic material mixing with rainwater or snowmelt in the upper area of the volcanic cone. In this scenario lahars could be moderately small and mainly affect the area of the Cotopaxi National Park. The eruption ends up in that case being a VEI 2-3. At the time of publication of this report this is the most likely scenario;
b) the ascending magma pulses have higher volumes and greater speed of ascent. This makes the high pressures produced the volcanic vent violently (explosively) open and paroxysmal eruptions VEI 3-4 (type Cotopaxi June 1877, November 2002 Reventador, Tungurahua August 2006) occur. Such happens with the generation of pyroclastic flows on all sides as the central character crater, predominantly towards the wind direction. Pyroclastic flows can reach the foot of the volcano. Contact between pyroclastic flows and the glacial ice produces a melting glacier. This liquid formation part of the lahars that descend by one or some of the drains that are born in the volcano are monitored. These lahars would become moderate to large size and could travel tens to hundreds of kilometers by river valleys leaving deposits which are meters to tens of meters thick. Additionally production of sharp falls of ash and lapilli (gravel) associated with this activity is possible. The shell thickness drop could reach more than 2.5 cm to more than 50 km of the volcano on the main wind direction. In general, to paroxysmal eruptions, there could be other smaller eruption sources which would be declining in intensity then activity would cease for several months or years. Depending on what the size of eruptive episodes are or not more diverse lahares are possible and they could be much smaller in volume than the main event flow. The final size of the eruption is a VEI 4. At the time of publication of this report, this scenario is less likely than a);
c) this scenario does not completely rule out a possibility of decrease of the eruptive activity in case the new intrusion of magma does not rise to surface areas. However, based on monitoring parameters and volcanic history of Cotopaxi, this scenario is the least likely.
These scenarios can be changed according to the evolution of the volcano's internal events..

Stirring the pot... so to speak.. or "Volcanic Connected-ness"
The repeated after-shocks coming from the Chilean 8.3 quake have been helping apparently to increase the spiky volcanic pulses, the rock fault "breaking activity" within the magma chambers and pipes that make up the CotoPaxi underground geological system.
Note prior and after the 6 minute aftershot event (about 12:47 PM local) in the graphic below - low spike events prior (take a look above at post 118 also, similar spike increase proceed after the long duration aftershock event) and then increase of number/intensity/duration of the spike events afterwards..

The volcanic tremor and breaking spike-like activity had been slightly increasing with some characteristic "double-pulse" as noted in Ecuador's eruptive volcanoes, when about 0530 local time, some larger events occurred, leading to about 20 minutes of strong seismic activity. Double pulse strong events were continuing into the later morning hours.

Current activity - NIL
Interesting, there are seismic "bumps", minor events and a few stronger ones now and then, but sustained activity has dropped substantially in the last day. As these events tend to be "cyclic", one should not consider that a movement towards "all clear".
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015093000.gif
The Volcanic Geophysical Institute who is monitoring, had decided to send a portable SO2 (Sulfur Dioxide) toxic gas monitor to see what changes in concentration are present downwind of the Volcano. They had reported due to previous ash-fall events, the sensors that are placed around the Volcano to monitor for such emissions, have been less responsive, and not necessarily producing the most accurate concentration readings of the toxic gas.

Stealing Bob's thunder here for a moment (thank you for all these updates!), I heard this from a friend today:
A source close to [Ecuador's President] Correa told a friend of mine that there is 100% certainty of a very major, possibly catastrophic, eruption within the next few months.
That could of course be quite something. I live several hundred miles to the south, well out of harm's way, but it's certainly a topic I'm most interested to keep closely informed about.

Thanks for the observations Bill - since the 8.3 Chilean quake, the ring of fire on this side has been pulsating, with a slow wave. Possibly that contributes to a higher earthquake/volcanic activity cycle. Keeping an eye on these..
Updated - just checked the Geophysical Institute site on the latest interpretation of the fly-over's which were recently accomplished. Concern on the CotoPaxi glaciers about some spots with rapid melting.. and secondary Lahar's being formed.
They do have cameras which monitor the streams for sudden increase or decrease of flow.

VLP's - very long period earthquakes, a type of slow tremor has been continual for the last couple days - from: https://vhub.org/resources/362/download/Waite_LF.pdf (a discussion of what slow-wave, tremor, and assorted "events" discussion) is being observed in one of the seismic recordings on CotoPaxi.
VERY LONG PERIOD EARTHQUAKES
Characteristics noted
• Observed at most active volcanoes having sufficient instrumentation
• basaltic to dacitic in makeup
• events tend to be explosive and effusive
• single pulse or oscillatory
• Likely involve fluid-flow on much longer time scale than tremor or LPs
What appears likely, one is noting fluid flow of magma against one (or more) of the magma pipes.

This is interesting, but I double-checked the time zone conversions. I'm not certain I didn't make a mistake (Bob, can you possibly recheck?), but here's what I got:
The 8.3 earthquake was on 16 Sept 2015, at 22:54:30.9 UTC (source: this post (http://projectavalon.net/forum4/showthread.php?85299-M-7.7-offshore-coquimbo-chile--upgraded-to-8.3-) from the EMSC/USGS)
Using timeanddate.com (http://timeanddate.com), I checked what time this was in Geneva, Switzerland, where CERN is. It told me it was then 17 Sept, at 00:54:30.9 (i.e. nearly 0100).
That's two hours before the 0300 CERN peak.
So, CERN could not have been the cause.
The only refutation for this would be if the read-out on the CERN graphs were NOT in local time. But in the video, the narrator states that the CERN data is indeed in local (Geneva) time. So, based on what I think we know here, it looks to me that the guy made a mistake in his correlations.

It looks like the Chilean 8.3 showed up on the CotoPaxi graphic as shown here below, and continued to evoke slow-wave oscillation for some hours afterwards. Appears to be about 1801 PM local time in Ecuador, the main event showing up as lasting 6 minutes.

The first aftershock showed up at about 1815 PM local time Ecuador, lasting for about 2 minutes. After these, seismic slow-wave, volcanic tremor, with periods of 7-8 cycles per minute started and continued for an hour and a half.
Time difference between Quito, Ecuador and Geneva, Switzerland is:
+7:0 hours
Geneva is 7:0 hours ahead of Quito
That means when it is 6pm in Quito, it is 1 am in Geneva
At 1801 PM Quito, Ecuador (6:01pm), to GENEVA local, looks like, even with what differs by a few minutes from the EMSC/USGS posting for time as to when thing started shaking on CotoPaxi.. It looks like 2 hours earlier the quake was than the 0300 CERN (local time) peak quote as you've noted.
By 2000 PM Quito, (the two hour afterwards period) there was no evidence of any event, shaking, or tremor on the CotoPaxi graphic.

Shortly after 0100 am local time, CotoPaxi started to exhibit longer and stronger periods of volcanic tremor, with some explosive events. Tungurahua about 100 km south had started eruptive activity shortly after midnite local time and CotoPaxi possibly had started to track on the magma activity in the region with it's own increase in activity. Near 0430 am local time a classic double pulse strong explosion was noted in the graphic.

From about 2110 for an hour the CotoPaxi volcano was experiencing slow-wave volcanic tremor (6 cycles per minute) with a fast wave of about 45 cycles per minute overlain.

Very large seismic even shortly after 0600 am local time rocked Ecuador's two volcanoes being monitored - cotopaxi and tungurahua
Tungurahua as well remains active with explosions. These large seismic events being picked up by the sensors on the volcanoes are punctuation points, which one should use to see if increased magma and volcanic emission activity changes (increases or decreases)..

It was assumed that the large seismic events being felt in the volcano's up north would do something to the magma chamber stability.
Apparently it has free'd up some trapped magma feeding into CotoPaxi.
The volcano had a couple LARGE explosions at about 10 minutes after 0800 am, and then again about 1230 local time today.. Eruption activity then started by 1300 and lasted for about an hour..

The particular "double pulse" pattern on the Tungurahua has taken on a more abrupt explosive characteristic. It has also happened on the CotoPaxi volcano. Such happens when the magma in the piping system is blocked, rock melts, the gases escape, mix with water, and explode.. It is a characteristic that shows strong potential activity can happen. It is advanced warning.
Why monitor Ecuador's volcanoes?
The geophysics group at correo.igepn.edu.ec has a very good sensor system and available data. This quality of data is hardly available elsewhere on the Ring of Fire volcanoes.
What it means to me:
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..
Good day on CotoPaxi:
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2015120112.gif
What is being watched for is double pulsing, prolonged volcanic tremor, slow wave oscillation, and spikey events, and of course seismically strong explosions (with ash and steam, potentially lava flow, lahars) and strong coincidental regional seismic activity (indicated on the sensors of more than one volcano).
For instance monitoring volcanoes in Mexico and Ecuador, one could watch for periodic building or diminishing seismic waves in the Ring of Fire channel (plate boundary zones).. It is known that destructive and constructive interference can occur in a plastic medium (magma is considered a plastic medium that can deform).. If the peaks happen under for instance the Cascadia range, within the plate boundaries, that additional "energy" could very well cause a further melting and abrupt SLIP (earthquake).. and a potential eruption.. To me it's worth watching and reporting what is seen.. so that further studies can be taken to understand this phenomenon.

More strong earthquake activity and volcano response to such. CotoPaxi responded with increased periods of low level volcanic tremor, and Tungurahua responded with some larger explosions.

the patterns were noted in the days preceding, but predicting volcanic activity is not really a science at this time.. One can observe particular trends and signatures in the seismic signatures, and look at volcanic magma movement in the surrounding channels, and see what is happening up and down the Ring of Fire, and make some educated observations, and issue some appropriate warnings..

Despite signs of slow-wave volcanic tremor, and spikey activity, and rather large explosions, the National Park at CotoPaxi has been re-opened to the public. http://cc.amazingcounters.com/counter.php?i=3190880&c=9572953
Cotopaxi National Park opens with security measures for visitors
119 days after the close of the Cotopaxi National Park, government officials announced today, December 11, 2015, the reopening of the protected area for the enjoyment of visitors.
The decision is based on monitoring reports and monitoring of the Geophysical Institute of the National Polytechnic School (IGEPN) indicating that the volcano in recent weeks has shown a decrease both internal and surface. In addition, the Risk Management Secretariat (SGR) has recommended that yellow alert while continuing visits could be controlled by trained personnel.
The Ministry of Environment (MAE), in coordination with the SGR and Security Coordinator (MICS) Ministry has worked to ensure the safety of all citizens who visit the park, through the provision of telecommunications equipment, articulated the System Early existing alert. It has also enhanced internal communication, providing personnel with portable radios, connected directly to the Integrated Service Security ECU-911. With these instruments delivering timely warnings to rangers and visitors is ensured.
The Foreign Ministry also developed a contingency plan that includes shares outstanding during the yellow alert. The plan is a diagnosis, analysis of vulnerabilities and threats. Lands in prevention, risk control as alarm and communications protocols, emergency detection, and operational procedures for guards, technicians and administrator area.
The absolutely MASSIVE explosion at 0708 am today was a sign that the volcano is hardly safe, and reopening to the public is clearly not the smartest thing to do..

The volcano was giving indication of eruptive activity may be coming.. I pointed out the explosions, the spiky activity and volcanic slow wave oscillations.. Apparently the seismic activity (shown on both the cotopaxi and tungurahua seismometers) was enough to kick off the eruption.

A large explosion at 0338 about the time of the maximum full moon. Then calm until about 0700 local, and an increase of unsettled activity, rumbling and high frequency seismic activity. The other volcano further south near Banos was experiencing very sharp, abrupt explosive events as seen on the seismometer..
A period of eruptive activity could start up once again at CotoPaxi.. It looks like the magma channels fill, and the magma moves around, with emission from the various locations.. Earthquake activity appears to induce magma movement or re-channeling..

A question to ask would be, where is the current magma reservoir located and where is the pressure being relieved? (which volcano, or if not relieved where will the next eruption happen? These volcanos sit on the "Ring of Fire", a system of interaction zones, which extend northwards, up the west coast of the US, through Alaska, over into Japan, and southwards into Indonesia).

The CotoPaxi volcano is not fully quiet - eruption briefly resumed this morning:
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016010812.gif
The earlier question was, where is the magma currently? Apparently it was being blocked, which what happens in that case, pressure builds up, then a release happens, then a dwindling happens if the pocket rapidly empties. We shall see if this resumes as it did earlier in the month.

Volcanic activity diminishing to a brief explosion now and then. Small periods of slow wave and spikes are continuing, so it is not fully "asleep" just yet..

Both CotoPaxi and Tungurahua volcano's output has reduced substantially to an occasional large explosion now and then with smaller outbursts, and spike activity continuing. The region is still experiencing large seismic quakes of about 2 minutes in duration, showing that the region is still unstable. (they don't look like aftershocks). When the seismic event bursts happen there is movement of the magma below, indicated in the seismic graphic recordings.

Note the double seismic pulse at 0322 am local time, and the increase in spike activity afterwards.

(Server has been intermittent for the last couple days - back now)
During the night there was a long sustained "event" which could have been a low level eruption from the volcano. Over the previous recent days, activity has been diminishing with spikes in activity (rock fracturing), and brief small explosions. On occasion a larger explosion now and then was noted. The event during the night is the most significant activity (that was able to be seen and retreived from the server) recently.

Lahar activity on the western face of the volcano had been observed for a sustained event on the 13 of about an hour. (lahars generally consist of mudslide, water, rocks and ash contributions) http://cc.amazingcounters.com/counter.php?i=3190880&c=9572953

Spikey activity is still happening an indication the volcano is not asleep, but in a "calm-mode". There is still evidence of slow-wave activity indicative of magma movement within.
Tungurahua volcano to the south near Banos continues to show brief spikey activity and an occasional large explosion, and is not fully 'asleep' either.

The last couple days (and nights) have had a few large long duration seismic quakes recorded on the volcano's (CotoPaxi and Tungurahua) seismographs.
Today, CotoPaxi's seismometer network recorded a series of pre-eruption events, consisting of slow-wave, spike events, some large explosions, and smaller explosions, with regular periods of "event activity".. these indications could be a precursor to a larger sustained event like the previous eruption cycle.

The seismographs over the last week have been picking up strong regional earthquakes, and the CotoPaxi volcano's underground magma pipes and chambers appear to be reacting
Top graphic CotoPaxi from last nite, bottom graphic from the Tungurahua volcano.
Solar - NOAA forecasters estimate a 45% chance of minor geomagnetic storms on Jan. 25th as Earth passes through a stream of solar wind flowing from a coronal hole on the sun. That could be the reason for the regional earthquake activity.
Note the seismic earthquake event at about 0330 am local time on both graphics. At about 0630am local time an increase of magma activity, low frequency slow-wave, and spikey activity picked up on CotoPaxi.

Despite very strong regional seismic activity (earthquakes) recorded on the two volcano's CotoPaxi and Tungurahua - both volcano's magma channels appear to be addressing the shifting and stabilizing rapidly. That is a good sign. I wonder where tho the volcanic activity is relieving?

With Tungurahua decreasing in output, the magma channel has moved to a different direction, and I've been watching the other volcanoes to see where..
CotoPaxi volcano has shown periods of higher eruptive activity, waxing and waning, however brief pulses continued. In the early morning hours a brief eruption happened :

Bob
25th March 2016, 21:29
For the last day volcano CotoPaxi has calmed down, and eruptive activity is shown nil, with rock fracturing and a slight tremor now and then.. As the unpredictable nature of these volcanoes precludes any statement that the eruption period is highly diminished, or even 'calm', we should watch this volcano for increase in activity.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016032512.gif
The strong periods of sustained seismicity have been appearing over the last few days.. could be a precursor to an eruption event. Within the next day or so earth's geomagnetic field will be subjected to a solar particle influx leading quite possibly to a 'storm', and subsequent dissipation of the energy (earthquakes or volcano eruptions)..

The pattern of eruptive activity is matching. Starting with a seismic event and within 2 hours the eruption..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016041600.gif
Seismic slow-wave activity is present, which could indicate a larger eruption is possible. Events from Japan were seen in the seismographs yesterday as well, followed by increased seismic activity with the CotoPaxi volcano. The oscillation within the Ring of Fire (from Indonesia in the west to Chile) apparently has been happening from the Japanese events. It is unknown if these are contributing to the Ecuadorian seismic events (and eruption). There have been solar events in the last few days (particle storms from the Coronal holes).
Bob
16th April 2016, 16:06
Close to 0800 am this morning a large seismic event appeared, about two 1/2 hours later (as before) periods of low level sustained seismic activity started to appear. Slow wave components were very present and potentially show an eruption event could happen while magma pressure is diverted from the main tubes. Keeping an eye on this -

One can see the large quake on the Cotopaxi volcano's seismographic (bottom of chart).. I mentioned earlier the strong slow wave, which can be an indicator of more activity is pending, as it was.. (see the graphic in the previous message) - about 8 hours advanced warning started showing up.
The rocking and rolling has gone on for at least an hour:
CotoPaxi

Tungurahua (both volcano's seismographs indicated the strong shock event)
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016041700.gif
This could trigger eruptive events, and/or change magma flows. As I said above, keep an eye on this..
Bob
17th April 2016, 19:37
Today's activity - the main shaking is calming down (top of graphic), followed by regular slow wave periods of seismic activity. Such "rolling" can proceed an event (eruption, earthquake or aftershock). Don't be volcano 'mountain climbing' with these events showing up..

Eruption activity continued through the nite.. Seen within the eruption signature were aftershocks pulses.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016042000.gif
The Tungurahua volcano seismograph points out the aftershocks clearly.
4 minutes in duration and the longest being 8 minutes in duration. (see below)
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016042000.gif
It's possible the large prime event quake from the other day 'jump started' CotoPaxi into new periods of eruption.. Monitoring these volcano's over the last few months, certain activity was noted, which has been previously seen prior to a major seismic event, i.e. 'earthquake'..
During this episode CotoPaxi has been experiencing strong aftershocks, and within 2-3 hours of the seismic pulses, starts to erupt.
Bob
20th April 2016, 22:50
CotoPaxi continues to apparently respond to the aftershocks..
After 0810 am Local time, the eruptive period which was going on since 2030 pm 19 April stopped. During the interlude there were 4 major aftershock events, and during the last two, slow-wave activity started (indicating an eruption may be in the offing).
Right after that last aftershock, the eruption started up again..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016042012.gif
As the intensity of the aftershocks are so great, and Tungurahua volcano currently is not erupting, one can cross-correlate the seismic aftershocks with that volcano's seismographs and match timing:

Calming within the CotoPaxi volcano.. Diminished aftershock energy from the main seismic event off the NW Coast of Ecuador (the m7.8).. What can be seen are a few aftershocks as well as clearly defined slow wave (and harmonic oscillation, something like when the right "note is hit", through resonance, a buildup in energy can be noted, and then released)..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016042400.gif
A brief period of eruption occurred about 0500 am local time.
Into the morning and early afternoon is the graphic below.. There is harmonic oscillation AND slow-wave within the graphics after the small eruption and prior (during the early morning hours, top graphic).. Is this pattern about something new and stronger in the offing? (see Bill's observations in the Ecuador 6.1 thread)..

The patterns of eruption are cyclic as can be seen in above's post, precluded with slow wave and harmonic oscillation within the "shaking" (seismic) events. Keeping an eye on this..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016042512.gif
Tungurahu's monitoring can be used to show the aftershocks.. It is possible that the large 7.8 event redirected the magma channels in the area.

Good news with the eruption situation on CotoPaxi http://cc.amazingcounters.com/counter.php?i=3190880&c=9572953
diminished to zero eruption was apparent during the night at the volcano.. However strong aftershocks were still being received by the seismic monitors near the volcano. No strong harmonic patterns nor strong slow wave was noticed in last nite's graphics.

After an evening and early morning of quiet (punctuated by aftershocks), slowly and increasingly, periods of harmonic oscillation and slow wave appeared, which then followed periods of eruption..
At the same time, when the resumption started with CotoPaxi, volcano Tungurahua far to the south started periods of increased unsettled activity in the seismic monitors. Such built up continually without slowave or harmonic oscillation..
What we may be seeing then is the regional "period of activity cycle" where the bottom of the cycle (was not really showing us that "it is over") marked one part of a much larger, longer period cycle.. Somewhat like looking at how a 'rogue ocean wave' can appear out of the blue in moderate to high seas.. the "big one" may still be there, just catching up.. with the smaller cycles..

There was a strong burst of activity during this eruptive period -
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050100.gif
The cyclic surging showing up in the seismic graphic is interesting in my opinion.. (see the seismic graphic readout for last nite and into the early morning hours in the above post).
Pattern: There is a long period slow wave followed by saturation of the seismic detector, brief calming, then resurging.. as if a large wave is pulsating and finding a way to release energy through magma.. A system seeking balance?
The eruption continued thru the early morning hours, diminishing shortly before 1000 am local. By 1030 a cyclic period of activity resumed once again.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050112.gif
Cyclic period is changing slightly, to a longer cycle and daytime eruption, starting in the afternoon. What is interesting about this graphic is classic harmonic oscillation associated with magma surging appears to be present, and then building.. Right before the eruption starts, spikey activity presents itself.. The harmonic oscillation starts peaking, and the cyclic period shortens dramatically, to less than a minute gap between bursts... Then the eruption happens 11 minutes later.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050212.gif
With the apparent change in the eruptive period, the activity cycle appears to have moved earlier in the afternoon for the starting.. (see below, about 1610 local time)..

http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050312.gif
Continued thru the night:
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050400.gif
and into the early morning hours. It was still "rumbly/noisy" at 0900 am local - an earthquake can be seen at about 0837 am local.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050412.gif
the Tungurahua volcano's seismograph also points out the seismic event close to the same time, but EARLIER, indicating the epicenter is closer to Tungurahua than Cotopaxi's seismic center. That timing of "Events" can be useful for seeing if local activity is happening (earthquakes), or aftershocks are happening.
Regionally, there could be instability, and fault movement.
Looking at the last 30 days earthquakes and aftershocks (it is eye-opening, the quantity which happened in the upper NW area... both onshore and off - larger size bubbles equals larger quake):
http://chanlo.com/images/aftershocks.jpg
This could possibly be contributing to keeping CotoPaxi's volcanic magma channels active (and emission from the Volcano)..

Hi Bob, just noticed we're starting to get an uptick in EQ activity over the last couple of hours, one down here by us in NZ and Mexico just had a 5.6M a couple of hours ago, quite shallow. (22:27 UT). I keep forgetting we're 12 hours ahead of UT so my earlier times were a bit premature.
Right now (1232 NZ Time on 6th May) we're a few hours away from a close Earth & Moon line-up with Venus (which started a few hours ago), then the Sun & then Mercury. (My earlier "hunch"). Hope I'm wrong.
And there appears indeed to be an uptick, earlier 1530 local Ecuador time, eruptive cycle starts again.. with the harmonic oscillation, that appears to be related to magma movements

As I suspected. OK, right now Moon is centered over the Pacific Ring of Fire with a lean toward the Asian side, and the Sun is "centered" pretty much the same area. I'm anticipating (but hoping NOT) for QUITE an uptick (I don't think major at this stage, but who knows???) . If you look at USGS, we've been having smaller ones all over the place about every 15 mins so far. What's the "translation" trend of your graph showing??
(BTW Im a hooge airplane nut - what's the airplane ur sitting in on your Avatar? Is it a Duke?? :))

This is not good... Earthquake Swarms under Mt St Helens increasing, Washington
http://www.theguardian.com/world/2016/may/07/mount-st-helens-earthquakes-detected-washington
Apparently going on for a month .. they say "nothing imminent.." but magma is moving around, maybe refilling the main magma chamber(s)... The so much seems to be what may be happening with CotoPaxi - there are swarms and magma movements, AND periods of gaseous eruption..
The U.S. Geological Survey said Friday they have discovered a swarm of small earthquakes underneath Mount St. Helens since March, which could mean it’s recharging with magma.
Scientists said the Pacific Northwest Seismic Network detected more than 130 earthquakes, between 1.2 and 4 miles deep, in the region since March 13. Researchers said the majority of the quakes have registered as a magnitude 0.5 or less and some are too small to detect.
There’s no indication there will be an eruption anytime soon, scientists said.
that there is activity up and down this side of the ring of fire is important to keep an eye on. CotoPaxi and Tungurahua are great indicators.. (as are a few others to watch)
Through the late evening starting at about 1600 hours, and into the early morning hours, eruptive activity continued within the volcano CotoPaxi.
This is currently an 18 hour eruptive cycle as of the time of this post.

http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050812.gif
Looking into the evening's seismic reports, CotoPaxi was very quiet.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050900.gif
Spikey activity was seen throughout the nite, and then near 5am local time, harmonic slow wave oscillation started back up.. Spikey activity is associated with rocks fracturing under pressure. Harmonic slow wave is associated with magma movements.
Then in the daytime morning hours things changed a bit.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016050912.gif
A large afterhock or regional quake event appeared shortly before 0800 local time. Two hours afterwards (the apparent cyclic time to "respond" to the shock), strong harmonic slow wave activity appeared in CotoPaxi.
What appears interesting (see below), Tungurahua volcano to the South near Banos became active, as if the shock was able to free up magma movement in the Tungurahua volcano. (see graphic below).. refer to the corresponding times in the CotoPaxi seismic graphic above. It can be seen where there is any regional correlation and when UNIQUE activity is happening.. This increase in activity in Tungurahua may indicate a magma shift to that volcano. It may be too soon to look at "predicting" more activity at Tungurahua. I didn't see harmonic slow-wave signatures in the Tungurahua seismic graphic, but what was noted is Tungurahua's signature DOUBLE-PULSE events (big explosion followed by a slightly smaller one, in close timing).
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016050912.gif
Again during the day we see a calmer CotoPaxi volcano..

Triggers appear to be related to regional earthquakes, aftershocks, and magma channel molten rock movement. Noticing spikey activity, harmonic slow wave periods, and seeing these happening in cycles, seems to give some measure of local instability, and possibly with enough data from enough volcano seismic detectors, maybe further than regional activity could be a useful way to 'predict' earthquake and maybe eruptive activity..

Yesterday was mostly quiet during the day, and at night mostly spikey activity was noted with very weak periods of slow-wave harmonic activity was noted.
Watch right around 7am local time, the slow-wave harmonic oscillation tremors started to speed up, and gain in amplitude.
At 0915 am local time, then an eruption started.. Being able to look for the patterns gives some indication of when eruption is imminent :

Eruption which started near 1600 continued thru the nite, mostly stopping with strong continued instability being noted in the seismographic 0900-1000 am local this morning:

Eruption continued through the night - started diminishing 0400-0600 am local time -
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016051300.gif
By 0800 am local time, the intensity had dropped to continual high frequency vibration.. quite different than in previous days. This type of pattern has been seen before on the volcanoes during periods of regional instability (stress build-up in the subterranean rock strata).

You can see in the Tungurahua volcano, quite to the south of CotoPaxi, the spikey, plus pulse activity periods also happening during the late evening and early morning hours:
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016051300.gif
As the early morning sun rose, the large double pulsing in Tungurahua started to diminish, BUT there was an increase in HIGH frequency activity ALSO in the Tungurahua volcano:
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016051312.gif
Something to keep an eye on today this Friday the 13th..
Looking at the afternoon seismic graphics of both volcanoes, the 6 hour cycle appears to be present again.. Cotopaxi calmed down slightly, but started activity again around 1600 pm local, and Tungurahua did the same although some explosive events were 45 minute sooner.. Could be something up South of Ecuador is moving around deep..
A large 6.7 quake struck in the upper NW of Ecuador near where the 7.8 occurred - using the Tungurahua seismographic to show this and the vibration prior:
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016051800.gif
0258 local at the seismograph starts the event
it lasts for about 7 minutes and then 3 minutes later another pulse lasting 2 minutes
and
then 4 minutes later a smaller pulse.
6 minutes later a much smaller pulse which lasted for two minutes.
-----------
Prior to the quake event at about 01:45 am local there was a "triple" pulse event which was odd (haven't seen that before except during eruptions), followed by about 12 minutes afterwards, a very sharp and abrupt "spike" pulse - that was the sequence immediately before.
----------
North of Tungurahua, up at CotoPaxi, both seismic events and eruptive activity was happening:
Slow-wave (hard to see) starting at 1940 pm local time. At 2021 pm local time eruptive activity picked back up.
The large seismic event (the quake) can be seen mixed in (increased spikey activity) with the eruptive activity prior to 0300 am local time.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016051800.gif
Up on the ring of fire, up on the NW coast of the US, the event can be seen on two (selected) of the seismographs there (Mt. Hood).
It is interesting understanding the "connectedness". And seeing it for oneself on sensitive equipment. (we are told by 'experts' the volcanoes on the ring of fire don't see each other's activity.. hmm)
http://chanlo.com/images/Mt-Hood-1.jpg
The second quake as seen on the Tungurahua seismographic followed by the CotoPaxi seismographic - (BTW, there is a feeling of a low rumble, like a big truck passing in an elevated carpark, that type of low frequency rumble. My cats are a bit freaked out..
http://correo.igepn.edu.ec/heli/heli/RETU_SHZ_EC_--.2016051812.gif
You can see the quake and an aftershock(?) or a large event in the CotoPaxi volcano afterwards as well:
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016051812.gif
This seismographic gives us good detail of what's happening in the north of Ecuador (as well).
Continued activity from the last post (18th) till last nite, cycling mostly during the night, diminishing during the day..
This is the current set of seismographics :

http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016053112.gif
Spikey activity (rock breaking), and explosive events are able to be seen. Eruptive events are minimal at the moment.
Large seismic events noted:

After the large series of seismic events regionally, the eruptive events at CotoPaxi appear to have shifted from a night-time cycle to a daytime cycle.
This switching appeared to have started a few days ago. Coincidental maybe, but there has been a change in solar particle stream energy level directed earthward. (see the coronal hole thread (http://projectavalon.net/forum4/showthread.php?71579-Geometry------in-Solar-Coronal-Holes&p=1072767&viewfull=1#post1072767) in the solar activity reports part of the website for details).

Today:

Continued pattern of cycle switch with CotoPaxi - although there were a few night time events, the pattern of events appears to be now running on the daytime cycle.

The switch in cycles happened again with CotoPaxi - starting on the 8th, right after a large regional quake (1530),
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016060812.gif
and during the night
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016060900.gif
and into today
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016060912.gif
The seismic pulse pattern output started to take on a regular sputtering emission for about an hour, around 0700 local time.
Eruptive pattern continues in the night-time cycle with brief 2-3 hours of "off time" during the daytime, usually the afternoon before resuming at night.
A strong seismic pulse was noted shortly after midnight local time which lasted for 1/2 a minute of increased rumbling activity.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016061200.gif
After the "pulse" the recording network went OFFLINE.
Background seismic activity remains high despite the cycling appearing (night-time eruptive activity, diminishing by morning, and resuming as the sun goes down...)
Large seismic events have been picked up in both CotoPaxi's seismic monitors and Tungurahua volcano's seismic monitors at apx 1036am local.
Background microseismic events monitored on the Tungurahua's seismic monitors at the moment remains LOW.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016061512.gif
1400-1600 hours local time today (see post above for the seismic graphic), the eruptive pattern took a stronger emission pattern, which then subsided to a moderately low level of seismic micro-tremor. Microtremor as of this posting is still remaining constant.

This is very cool: it's a live webcam feed. I didn't know one could embed something like that. It's an animated gif, and cycles around in stop motion... but it's regularly updated. Yesterday evening, the image was pitch black, because it was night.
What that means is that if the whole thing blows to h***, we'll see it live on the forum here.
(This is not just a joke: I did hear, off-record, 6 months ago, from someone who knew someone in the Ecuador gov't, that they are '100% certain' of a major eruption, timescale not known.)
The animated gif stop motion camera feeds are good. Many of the cameras field of view will be showing the clouds, depending on the season, such are heavier/lower.. What I have seen many times close to sundown, or just shortly thereafter, the clouds will drop away.
I'm watching the cyclic changes on the volcanoes hopefully getting a partial underground 'visual' of what is happening.
Current morning/afternoon seismic graphic:

Slowly, after the event yesterday. 1400-1600 hours, the seismic signals started to show less micro-tremor. We can watch to see if the cyclic period picks up during the day and night.
In the post above around 1600 hours local, very small low amplitude periods of slow wave were noted. Slow-wave generally is indicative of magma movement. Today throughout the day from 0900 local time onwards, more slow-wave signals were noted, albeit quite small. The low amplitude values could be due to the particular location that the seismic recorder sensor is located is not directly near a magma pipe.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016061912.gif
Tungurahua to the south is showing continual "noisy" activity, but with minimal rock break signatures.
Both volcano's seismic recording sensors are continuing to report "noise" (low level microseismic activity) in cycles. CotoPaxi continues to show small slow-wave periods intermixed with high frequency activity.
There was a 4.5m seismic event (earthquake) which was 4 kilometers deep near the town of MANTA in Ecuador on the coast. This event appeared on both seismic recorders, but appeared stronger in the south, on Tungurahua's monitor.

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/VC1_SHZ_EC_--.2016080512.gif
brief sharp spikes (rock breaks) have appeared and then "quiet".

A small amount of slow-wave activity continues with CotoPaxi today. A burst of seismic activity at 0915 am local time and again, 1353 a bit stronger. Interspersed rock fractures were showing up.

During the day, slow-wave periods (about an hour about 0830-0930am local) plus spikey activity continued. Earlier about 0736am local, there was a small local seismic event with the volcano. At about 1317 there was a strong rock fracture signature spike, and two smaller ones thereafter.
At 1525 pm local there was a strong seismic shock from a regional earthquake. Shortly thereafter (1533 pm local), CotoPaxi experienced a strong seismic event, probably in reaction to the regional earthquake.
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016081112.gif
==post update==
Another event at 1713 pm local with continued rock fracturing.. keep an eye on this tonite and tomorrow..

Cotopaxi woke up briefly this morning with some low level "vibration" shortly before and after about 0800 am local. The volcano since the last report has been showing very slight intermittent slow-wave (magma movement), small rock breakage signature and general increases in "noise level" during the night, diminishing during the day. The seismometers near the volcano have been recording the seismic events of local and regional earthquakes. It is unknown if those earthquakes shifted in any way the magma channels and regional faults associated with potential magmatic/volcanic activity. We're continue to watch both volcanoes (Tungurahua and CotoPaxi). It has been noted that one of the Costa Rican volcano's has been active this past week.

This is interesting - we have been closely watching both volcanoes, Tungurahua and CotoPaxi and expecting to see more activity out of Tungurahua (Near Banos). I've noted before, tracking of activity between the two, the events happening in the magma channels below the volcanoes..
As Tungurahua has been calming (maybe), what I am seeing is a ramp up of CotoPaxi ...
There has been a lot of low level noise present on the seismic detector of CotoPaxi which we are monitoring, so one is having to look for peaks above the low level activity in the graphics..
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016100312.gif
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016100400.gif
Events were noted at about 1000 am local, 1035, 1046, 1251, 1359, 1415, 1434-38, 1535-38, and 1639 - there was slow-wave magma movement signatures present. Not sure if this is coming up to an eruption event but it is something to note where the magma may have moved to..
Still keeping an eye on this to spot any trends.

Strong event burst on CotoPaxi.
Tungurahua has been quiet except for strong rock breakage signatures.. Similarly CotoPaxi has been showing very abrupt very strong rock burst signatures.
For the last 4 days the Ecuadorian seismographic reports have been off-line, so no reporting has happened (if any events happened they were hidden due to the network being 'down').
The strong event was at 2021 local time.

Couple of strong bursts of activity on CotoPaxi - today Tungurahua in the south also exhibited a burst of activity. It seems a toss-up between the two volcanoes about eruption activity. The Ecuadorian geological reporting institute was feeling that eruption activity at Tungurahua (in the south) was more of a possibility than CotoPaxi lighting up.. It is hard to tell. Both volcanoes have exhibited swarms, bursts of activity, and have shown signs of magma movement (slow-wave in the seismographics)..

As expected with the strong solar and earth geomagnetic instability, a brief eruption at CotoPaxi today:
http://correo.igepn.edu.ec/heli/heli/VC1_SHZ_EC_--.2016102512.gif
Shortly before noon local time activity started with a low level tremor followed by periods of rock break signature impulses. An hour later, about 1313 local time the spikey activity increased into an outburst. Keeping an eye on this.
