Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
No signs of immediately stopping - although diminishing and cycling of the eruption levels (ash and steam/toxic gases), the volcano is not showing signs of immediately stopping. Advisories remain in place.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Explosions continuing, every 1-2 minutes. This particular activity (with larger explosions happening as the day progressed), started at about 2200 hours last nite..
by 1700 local time today, a brief respite happened where the explosions' period reduced to every 7 minutes. This will be watched during the evening hours.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Explosive activity this morning was tracking the seismicity in the region. Increased movement of the magma in the chambers appears to increase when seismic events (earthquakes in the region) are felt.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
The particular "double pulse" pattern on the Tungurahua has taken on a more abrupt explosive characteristic.
Why monitor Ecuador's volcanoes?
They have a very good sensor system and available data. Such is hardly available elsewhere on the Ring of Fire.
Monitoring the Ecuadorian volcanoes gives a good insight into the volcanic "Ring of Fire totally up along the pacific coast thru US Alaska and over in to Japan and southward from there."
It is critical to see if anything is happening there which reflects through the ring of fire. Even the Cascadia Range on the US west coast is affected..

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Another strong regional earthquake which evoked subsequent volcanic action in Tungurahua.. See below. At about 2245.. After this seismic event very strong explosions and eruptive activity started in bursts at the volcano. (see below)
this may clear or not depending on the magma channel contents.
CotoPaxi managed to survive the seismic hit (earthquake) without going into eruptive activity, but it was noted earlier, that a period of small volcanic tremor started up and lasted for an hour. tremor events usually mean magma movement in the plumbing system, and depending on the blockage in the plumbing, either it will melt gracefully and slowly or will radically explode.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Reporting on the update for Tungurahua, near Banos,Ecuador..
Tungurahua appears to be calming down while CotoPaxi up at the north appears to continually be experiencing large explosive events, and eruptive burst..
CotoPaxi - note the explosion at 2133 hrs local time

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Low level seismic tremor has started up and has been continuous on Tungurahua since about 1200 local time today. Outside of some large singular explosive events within the plumbing system of Tungurahua, it has been relatively quite over the last few days.. VT usually is a sign that magma is moving in the plumbing of the volcano, and could subside, or build up to an eruptive series of events. Spikey events have been a precursor to eruption as well as the VT.. Keeping an eye on this..
Cotopaxi in the north has had a few very strong seismic pulses recently, and spikey events but generally has calmed back down.. There were a series of regional earthquakes which showed up on both volcano's seismometers over the last day.. Possibly that could have triggered Tungurahua's plumbing to start moving magma around.

While continual eruption is happening at the normally quiet CotoPaxi volcano, in the south, Tungurahua continues to experience large long duration explosive events:

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua erupted today. There have been numerous repeated seismic earthquake events on the two volcanoes, Tungurahua and CotoPaxi over the last month.
at 0811 am, both volcanoes seismographs detected a 2 and 1/2 minute relatively small earthquake and about 1105 am local time, strong pulses of activity started on Tungurahua.
The graphic below shows activity continuing into the night..

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua volcano continues to erupt in couple hour bursts, with the higher intensity, followed by periods of explosive "puffs".
CotoPaxi in the North continues to exhibit a period of explosion seismic pulse(s), then changes to spikey activity, indicating rock fractures (or possible magma rock melting) - never-the-less things are shifting within the CotoPaxi volcano.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Eruption activity continues in cycles. A few strong periods, then very strong "simmering/boiling" like effects. CotoPaxi continues to have a large seismic explosion now and then some slow wave oscillation, then signs of rock fracturing (spikey activity). The Tungurahua eruption isn't as strong as past eruptions, never-the-less being very close to a city it's eruptions tend to be of a concern.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Eruption activity of Tungurahua continues -
It is cyclic and surging, or periods of diminished activity (like simmering, but still boiling), and stronger outbursts.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Throughout the night and early morning and into the morning hours, Tungurahua continues to erupt, a moderate amount, with brief peaks.
It is interesting on the west side of the ring of fire (this particular channel is being watched as it affects many in the regions it touches), a large seismic quake (and aftershocks) happened. Volcanoes up and down the "ring" could reverberate, and become active, or faults elsewhere could slip, along the "ring"..

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua eruption continues.
Looking at the seismographic of CotoPaxi, apparently that volcano's monitors did pick up the activity on the other side of the world, on the southwest extent of the Ring of Fire..
There was a reverberation noted in that "channel". There is a connection along the "ring of fire" with other volcanoes across the world, that which happens elsewhere along the channel is reflected throughout the channel. "We are all connected.." The concern next would be to see what happens in the Chilean area for seismic activity.. and to see if volcanic activity changes in the Ecuadorian volcanoes.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Emissive and seismic activity continues with Tungurahua - during the night the volcano had cyclic periods of emission and activity. CotoPaxi to the north in Ecuador is being monitored daily for any changes in patterns. Starting just before 0400 am local time, a series of strong seismic quakes were noted, followed by a large 3 minute duration pulse.
Three graphics follows, where the last one is the seismographic of "the pulse" shown from CotoPaxi :

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Emissive and seismic activity continues with cycles, with periods of reduced activity at the Tungurahua volcano. Activity at CotoPaxi continues to be "unsettled", with long subtle periods of seismic activity reminiscent of a slow earthquake (3 minute emissions), with brief bursts of seismicity.
Below is the seismograph for CotoPaxi - note the activity starting around 0100 am local time, this is indicative of what could be a period of magmatic activity, magma moving in channels deep within the earth. The spikey activity afterwards, around 0220 am local could be indicative of rocks fracturing, melting. Slow wave oscillation at 0253 am local time is indicative of volcanic activity, but no current eruption activity is shown.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Eruptive activity continues to show oscillation (periods of stronger and weaker emission). Large seismic quakes are happening within the region to the northwest of Tungurahua, (West of CotoPaxi), which could be allowing for magma channels to open up flows to existing reliefs (volcanoes).
Here one can see what a strong seismic pulse looks like as recorded on the CotoPaxi seismograph (seen in red top right @1955 pm local time). This large sized pulse was recorded to be 5.1 magnitude.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Noticing the seismic eruption pattern for Tungurahua is showing larger periods of diminished activity. Usually what happens it appears, is the magma starts to solidify, pressure builds, and an explosion and strong seismic event happens. If a large magma dome within the earth builds, fills, and then pressure appears on it, an explosion could be much larger. These smaller events provide for pressure releases.
CotoPaxi continues to show deep activity, and there are periods of increasing seismic tremor. Solar activity is "odd" with a reverse polarity incoming particle wave, creating a lot of auroras deep south spreading into Europe, the US, across Asia where Auroras do not happen often. See forum post here: https://projectavalon.net/forum4/show...=1#post1051556
This extra energy has to go somewhere, and historically weather events, volcanic events, earthquakes happen. Animals and people act differently.
