    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

    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).

    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.

    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.

    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.

    Tungurahua Ecuador Volcano seismic activity 3 June 14




    Strong high level seismic noise and sharp spikes are continuing with occasional magmatic events.

    Tungurahua - summary activity



    The 12th showed a lot of rumbling and some activity.






    With the solar particle stream from the 10-11th, having started to hit, there was some increase in activity as shown in the graphics.

    That ring of fire spot is a good pulse for the rest of the string, up the pan american thru US, Alaska, Japan and down to Indonesia.. Luckily they have a great reporting network..

    Watching the patterns in the graphics is fascinating - one can see the solar events tracking earth side events, when x-ray flares, and cme's hit. Worse so far seems to be when all 3 including Coronal Holes appear.

    Ecuadoran volcano called 'Throat of Fire' in local language starts spewing ash 28,000ft into air





    The eruption is latest after months of activity around Tunguarahua volcano

    Rose Troup Buchanan , Monday 01 September 2014


    An Ecuadorean volcano is spewing ash five miles into the air, closely monitored by experts, after an eruption this weekend.

    Ash from the Tunguarahua volcano, whose name means ‘Throat of Fire’ in the local Quechua language, was blown five miles, 28,000 ft, into the sky and drifted west.

    It was the latest eruption from the volcano after a period of calm.

    Tunguarahua volcano erupted on 29 July, 4 August and then again on 19 August.

    Homes nearby have felt the strength of the eruptions, with the blast causing windows and roofs to vibrate.

    Over the weekend the volcano started spewing small pyroclastic flows, a fast-moving current of hot gas and rock which can reach speeds of 450mph and temperatures of about 1,000 C.

    In pictures: The Tungurahua volcano erupts in Ecuador: 1 of 8



    The volcano has been classified as active since 1999, with frequent powerful ash explosions producing ash plumes and dangerous pyroclastic flows part of the population around the base has been evacuated.

    It is located in the Andes, 87 miles south of the capital Quito.

    It's a another blow for the aviation industry which is already reacting to the Icelandic volcano, which last night downgraded its aviation warning back to orange from red, and an eruption in Papua New Guinea disrupting air travel.

    Tungurahua - 30 September 2015 seismicity for the volcano -

    The Geological Institute who monitors the volcanoes in the Region, has started reporting on the Tungurahua volcano, that activity spikes and frequency have changed - they are becoming larger and more frequent.

    Tungurahua came to life briefly for about an hour - about 4 hours prior the the 2 hour eruptive-like event at CotoPaxi (which is far north.. a local City being Quito)

    An hour before midnite, Tungurahua came more to life, with continual periods of eruption through 0600 am local time:




    Eruptive activity stopped about 0830 am this morning. A few strong bumps were noted after the main eruption period stopped.

    Tungurahua erupted again starting with a little over an hour's smaller eruptions this morning preceded by 6 hours in the early morning hours (started about 0200am), then about 0955 am local time, a large explosion punctuated the start of another eruption cycle of about 6 hours so far.
