Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua Ecuador Volcanon - activity 11 May 14
Starting about noon yesterday there was a long duration seismic rumble of about 10 minutes which started small, built up and then diminished. Interspersed were small explosive events, which were preceded by larger events (about 1 minute for each).
At 1900 another similar type of event started, but was about 4X larger and continued for about an hour, a similar pattern (reminded me of tide rising and falling), or this was a very slow wave event of a large magmatic or deep stress release with a lot of large movement. There was no sudden abrupt shift, quake appearing.
About an hour later, another similar type of surge lasting about 30 minutes occurred, followed by smaller similar "moments", continuing at a lower level, with smaller surges, and smaller durations until about 2230 hours. A few small explosions happened later, with periods of gradual increasing background rumble, showing what was looking like a small harmonic tremor, repeating patterns and is continuing at a very low level as of the time of this posting. The patterns are like a train running continually over railroad tracks, with small spikes as the "wheels" click as they travel over the rails.. This is one LONG train

Tungurahua Ecuador Volcano - activity 12 May 14
High frequency activity continued till about 2200 hours this evening, looking backwards through the day, there were numerous small spikes but no significant activity until yesterday evening.

Tungurahua Ecuador Volcano - events - 13 May 14
After some rocking an rolling last nite and into the early morning, the activity diminished drastically, to spikey activity (small very brief impulse quakes).
the most dramatic images of the regional earthquake event was indicated on the G. Pichincha sensor (shown in another thread).

Tungurahua Volcano Ecuador events 15 May 14
Small spikey activity was occurring until the very large regional seismic event took place before 1800 hours local today.

Tungurahua Ecuador Volcano - activity 19 May 14
Activity in the form of micro seismic spikes, sharp abrupt pulses up to 300 per hour were occurring late last nite at the volcano. Activity this morning changed to less "cracking" and started to resume more puffing activity, magmatic in nature.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua - volcano Ecuador - weekly activity report 24 May 14
Seismic activity, (rumbling) was present at the start of the 20th period, with some peaking on the 21st as was noted with the other volcanoes of Ecuador that are monitored. After the period of brief activity on the 21st, vibrations, diminished, with brief swarms of small but sharp pulses. Activity started picking up with increasing frequency of microswarms (fracturing events) towards the 24th. The massive explosion predicted by the Geological Institute never happened, so they must be perplexed as to what is going on with the magmatic channels of the northern Andes volcanic arc chain. What I have noticed is the volcanic day and a half oscillation slow wave present in the Reventador volcano north about 100 miles of Tungurahua, and increasing activity in the previously relatively quiet CotoPaxi Volcano, and increasing strong oscillation periods happening at G. Pichincha volcano near the city of Quito.
If there is cone building, tilting, elevation changes in the region, that can indicate magma-gas buildup and there can be a massive explosive event, when the solidified cap frees itself. Volcanoes are dangerous and complacency with a quiet volcano is not a wise thing.. Stay aware stay tuned.

Tungurahua - volcano Ecuador - activity report 25 May 14
Sharp but small abrupt seismic pulses have been occurring in the volcano over the last 24 hours. Towards the morning time today, a series of small events, eruptions occurred.

Tungurahua Ecuador Volcano - activity status 27 May 14
Continual regular seismic spike activity is occurring, although nor large eruptive pulses have been noted in the last two days as of the time of this posting. This observation of no major predicted eruption of the volcano is a bit of a contradiction of the Geological Institute's predictions having traced magmatic activity and deep seismic traces of volcanic activity - the prediction changed after the 8.2m Chilean quake of 1 April, 2014, leading to apparent rechanneling of the existing magma rivers in the Arc Chain (of the northern Andes), reactivating normally previously quiet volcanoes as far up as Colombia/Ecuador border.

Re: Ecuador - orange alert issued in areas of influence of Tungurahua volcano
Tungurahua Ecuador Volcano activity 2 June 14
Increasing periods of continual seismic rumbling, regular and steady, interspersed with seismic short brief spikes and magmatic activity. This could be indicative of an impending "blow", however, harmonic resonance in the seismic signatures have not been seen in these graphics. Possibly the Geological Institute has satellite data on cone rise, and tilt indications. A [possible tilt was occurring today about 1700 hours local time.
