Ecuador - orange alert issued in areas of influence of Tungurahua volcano

[Bob]

eruption activity starts up again...

[Bob]

continued through the early morning hours and into the later morning..

==UPDATE==
The eruption has been getting stronger throughout the later afternoon..

[Bob]

Tungurahua continues to erupt - the Chilean 6.6 can be seen (within the eruption volcanic activity) shortly after 2000 local time

[Bob]

Stronger activity started about 0400 local time and continues -

[Bob]

and stronger activity still.. all day, and into the late night...

[Bob]

Midnite eruptive activity increased once again (as can be noted in the seismic graphic in the above post)..

The Volcanic Institute posted this image of the eruption -

The surface activity of the volcano has been characterized since November 10 by a continuous emission with a moderate load of fine gray ash. Emissions have reached up to 3.5 km CNS and were headed north, west and northwest. As a result of this issuance activity ash falls they were recorded in the sectors of Manzano, Choglontus, Bilbao, Mocha, Quero and Cotaló. In addition, since yesterday afternoon was observed output incandescent blocks from the crater to the north, northwest and east; these blocks came to about 500 m below the summit without reaching populated areas. The explosive rumbling has been constant in the last few hours, causing vibration of windows in the vicinity of the volcano sectors.

Today's seismic image (this morning) continues to show eruptive activity:

[Bob]

Eruption continues at Tungurahua, Ecuador into the night..

[Bob]

Explosive activity on the Tungurahua volcano - continues into the morning. Seismic output was strong enough to have periods of activity that was saturating the detector (overloaded) 0930 local through noon local time. Keep an eye on this.

CotoPaxi (shown below) to the north, about 120 km was showing seismic events, reminiscent of earthquake activity, which could be coinciding with the Tungurahua detector's saturation.

[Bob]

1400 hrs today, eruptive activity saturated (peaked out) the seismic detector again on Tungurahua.. Eruptive activity continues into the night:

[Bob]

Strong activity (eruption) continues, and has been non-stop since the 11th - periods of heavy activity has been saturating (peaking out) the seismic detectors monitoring the Volcano. Strong eruptive pulses started on the 9th and then diminished slightly at the time, but activity was picking back up on the 10th. The magma chamber/plumbing appeared to respond to the Chilean earthquakes and aftershocks, apparently free-ing up the plumbing to allow for flow to proceed out of the cone. Regionally, plate activity (seismic events) appears to be triggering volcanic activity as far north as Mexico.

[Bob]

Eruption activity has been virtually non-stop.

[Bob]

Briefly at about 0700 local, eruption activity, briefly diminished, and then restarted back up again:

==UPDATE==

Tracking seismic activity, again, saturating the detector indicating severe rumbling at the monitoring station.. from 1300 hours local time - this was visible, then appears to be being blocked from visibility to readers... hmm.. NOTE: if the image above is incomplete, refresh, or clear cache.. server in Ecuador appears to be overloaded at times with many people reviewing the data.. this activity at Tungurahua has been strong since the 9th..

[Bob]

Eruption with detector saturation (high levels of seismicity) continued thru the nite - at the moment, starting at 0845 am local time the emission levels markedly dropped by 1/2 (or the detectors were recalibrated to deal with the saturation) - unknown what is happening with the detector, however that can be sorted if high level saturation appears on the detector again...)

[Bob]

There were some periods of detector failure, and cyclic diminishing and increasing cycles of eruption activity..

Eruption activity was continuing at slightly less levels than a day ago..

An announcement by the US Embassy in Ecuador today:

U.S. Mission Ecuador

Security Message for U.S. Citizens

Tungurahua Volcano Alert Level Raised to Orange

November 18, 2015

The U.S. Embassy in Quito informs U.S. citizens throughout Ecuador that on November 17, 2015, the Ecuadorian Government raised the Tungurahua Volcano alert level to orange due to an increase in volcanic activity, primarily elevated levels of ash emission. According to the Ecuadorian Government, an orange alert means one must prepare for an adverse volcanic event. Tungurahua is located near the popular tourist destination of Baños, in Tungurahua Province, central Ecuador, about 180 kilometers south of Quito.

We strongly advise U.S. citizens residing in or planning travel to areas affected by Tungurahua to familiarize themselves with government evacuation plans in the event of a major eruption or further upgrade in the volcano activity alert level. Additionally, you should review your personal safety plans and ensure you have adequate emergency supplies, including face masks, food, and water.

[Bob]

The last eruptive burst before this respite showed up at about 1900 and ended about 2150 local. This current cycle has been quite active since the 9th. As Bill pointed out, folks are taking notice of the eruption activity..

Some sharp sudden seismic pulses are continuing, although the ash emission has diminished to hardly any output. This could start back up at any time, or remain temporarily quiet.

[Bob]

Activity is starting to resemble the period on the 9th Nov just before the continual activity in Tungurahua - the periods of seismic tremor and sharp spike seismic events are noticeable.

lower levels of eruption activity can be seen starting shortly after 0800 am which lasted till shortly after 1100 local time.

[Bob]

As seen above, eruption activity resumed, albeit slightly reduced.. This cyclic action can be noted by reviewing the patterns in the seismic graphics shown in the posts..

[Bob]

Eruption activity resumed and had picked up by early morning - watching this into the later morning hours -
