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

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

Space Weather tracking is reporting:

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

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

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

REVENTADOR VOLCANO ECUADOR appears to be experiencing major (eruption?) seismic activity.

this is a current LOCAL seismic signal graphic showing local time, Ecuador.

The eruption(?) period corresponds to the solar peak window as described in the earlier posts.

24 Feb - Tungurahua volcano, Ecuador - status CALM

seismic spikes, no indication of magma flow, no eruption evident

Tungurahua volcano Ecuador, STABLE, and CALM

We will temporarily suspend reporting on this volcano unless activity resumes

- Reventador volcano Ecuador currently is taking attention - it is EAST of Quito and currently tracking solar activity, and erupting.

Thank you for following this thread.

Tungurahua volcano Ecuador, starting to come alive again - 2 March 14

Small bumps, explosions starting to pick back up - no super large eruption at the moment.

The volcanic magma channel has switched, and a different set of seismic graphics are being used to track this movement to the newer location of feed.

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

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


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

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

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

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

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

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

3March 14 Tungurahua seismic activity - calming once again, with some small bursts of sustained activity, then calming.

[Bob]

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

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

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

Tungurahua - 5 Mar 14 calm - sleight seismic activity, random

The other seismic sensor (ARA) is showing intermittent seismic spike activity, but no indication of eruption activity at the moment.

[Bob]

Tugurahua - Ecuador's spectacular volcano came alive again today, 6 March 14 with a series of sustained eruptions corresponding to the solar zenith.

The early morning was punctuated by a sustain small level eruption of longer duration, about 7 minutes. Normally the eruptive periods last about 2-3 minutes.

Larger eruptions occurred after midnight locally.

Two large solar coronal holes are currently earth facing, and the increase of solar particle influx should reach Earth by the window around the 8-10th of March

The above pix depicts how the magnetic field lines on the solar surface from the coronal holes facilitate the ejection of solar particles (which eventually reach the earth and their "energy" has to be absorbed leading to changes in volcanic activity, and earthquake levels and sizes)

[Bob]

Tungurahua volcano Ecuador today was showing signs of calming down with slight seismic bumps - 7 March 14, it is considered an ACTIVE volcano.

It appears that the magma flows have moved northward once again as indicated for the seismic activity showing up at the Reventador volcano.

[Bob]

Tungurahua shows some activity once again, but not a large eruption event for 8th March 14

[Bob]

Tungurahua volcano Ecuador, has been reported locally of exhibiting sounds like gunshots, with an eruption outburst every now and then. Geologist services in Ecuador are wondering if it is going to start a new large eruption cycle.

2 minute, 4 minute and 7 minute seismic event periods are being observed.

[Bob]

Tungurahua, the often spectacular volcano of Ecuador, near Banos, appears to be having lava moving to different plumbing systems than recently. The earlier original seismic graphics are now coming active once again. 10 March 14

[Bob]

Tungurahua has been setting off some booms - seismic activity today shows such has been happening - 11 March 14

The magma apparently has again moved again to another "plumbing" channel.

[Bob]

Tungurahua today 12 March 14 continued to show a small eruption pattern of creating "seismic bumps" that match the magma events.

Yesterday a 16 minute long event occurred followed by a large 6 minute event.

[Bob]

Tungurahu today, continued to show some small but high frequency spikey seismic activity during the morning until LATER in the DAY, when some synchronized activity happened with the other volcanoes in Ecuador.

Good to see the seismic reporting network monitoring once again these volcanoes in Ecuador - the network was down 12 March 14 from about 1430 through 13 March 14 1900 hours local

(above shows a different seismometer looking at a different part of Tungurahua)

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

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

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

[Bob]

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

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

Thanks for this information you are providing!

Tungurahua seismic activity for 16 March 14

Significant - the event at Tungurahua volcano at approximately 1030 am local time is tracking wit h the event at the CotoPaxi volcano which is northward by a distance of 54 miles - this indicates a connection in the plates, possibly the magma river deep below most likely exists that is feeding all these active volcanoes.
