CotoPaxi Volcano - Ecuador seismic status

[Bob]

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.

==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..

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.

[Bob]

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)..

[Bob]

As expected with the strong solar and earth geomagnetic instability, a brief eruption at CotoPaxi today:

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.
