    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.

    The events are continuing as of the time of this post.

    CotoPaxi Ecuador Volcano - activity 6 May 14

    Activity continued to stay at higher elevated levels. A large explosion occurred at 0530 am local time. Microseismic tremor (low level) continued during the morning, until a very large sustained seismic event occurred about 1004 am local lasting for about 3 minutes. Microswarms continued for periods of up to 15 minutes, with some harmonic tremor present.

    Small explosive events started about 1403 local (about 4) then at about 1530 a larger series of microswarms occurred, lasting for up to 50 minutes, with higher peak activity during this period.

    Larger magmatic events started to pick up about 0600 am local, with smaller seismic events earlier in the morning and late evening yesterday. After 0800 smaller seismic spikes were continuing, with some smaller seismic long sustained activity, and a brief smaller magmatic event.

    Coronal hole, large, earth facing


    24-hr max: Kp= 4 unsettled predicted over the next 24 hour period.

    Such instability has been coincident with higher volcanic and seismic activity.

    The volcano continued to show seismic activity last night thru the morning. Starting after 1300 a large 5 minute significant seismic event appeared and unsettled seismic activity continued for at least an hour longer.

    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.


    At 0805 am local, there was a strong quake spike.


    A large coronal hole continues to spew particles to the earth.

    The planetary index of geomagnetics is showing a spike in activity

    The volcano continues to exhibit strong events. Seismic sustained and numerous sharp abrupt spikes are occurring as well as an occasional magmatic-like pulse.

    0138 local time one can see the regional seismic event which was shown clearer on the G. Pichincha volcano's seismograph. Strong activity throughout the morning was present with the volcano with micro-tremor, harmonic resonant events, spikey strong quakes and strong double pulse magmatic events that are synonymous with this volcano.

    There is a very interesting solar Coronal Hole (SPLIT) currently earth facing (see below)

    CotoPaxi Ecuador, Volcano - activity report 13 May 14







    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 Volcano Ecuador events 15 May 14

    Rocking and rolling, with sharp rapid seismic events, microtremor, harmonic tremors and a long sustained high level quake before 1800 hour local marked the day. The late nite was quieter but punctuated with some very intense sharp short quakes..

    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.

    CotoPaxi Ecuador Volcano - activity report 25 May 14




    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.

    Continued strong activity is being observed. Strong seismic activity, and long duration period of harmonic tremor, numerous microseismic pulses are present, and large sustained events. Close to 12 noon local time, a series of sustained pulsation events was noted. The events noted on the morning of the 26th were particularly worrisome.

    Increasing periods of magmatic activity, harmonic tremor and sharp seismic bursts were noted in the period above shown. Caution and vigilance should be noted.
