Tungurahua volcano (Ecuador): increasing degassing, crater glow

Sat, 14 Sep 2013, 09:30 | BY: T

Current seismic recording from Tungurahua (RETU station, IGPEN)

The volcano observatory reports a change in activity, which could herald a new eruptive phase in the near future. Starting from yesterday at approximately 17:00 (local time), increased steaming and gas emissions were visible, producing a column reaching about 1 km height. Incandescence in the crater area could be detected at night as well.
Previously, activity had been consisting of weak steaming producing a column of less than 200 m height.
Seismically, there has been a slight increase in the number of events related to rock fracturing and fluid movements within the volcano, but seismic activity still remains at a level considered moderate to low.

Tungurahua volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 August-13 August 2013 (New Activity / Unrest)

IG reported that seismic activity at Tungurahua was moderate to high during 7-13 August; the seismic network detected long-period earthquakes indicating fluid movement and some emissions. Although cloud cover mostly prevented visual observations of the crater, plumes were occasionally observed. On 8 August an ash plume rose 2 km and drifted W, and ash fell in Choglontus (SW). ...

Tungurahua volcano (Ecuador) activity update

During the past days, a further increase in activity of the volcano occurred, characterized by the generation of large explosions and a constant ash eruption column, and several small to big explosions that generated strong vibrations and rattled windows in villages near the volcano. An eruption at 07:23 (local time) on 28 July generated a small pyroclastic flow that affected the upper north and north east flank of the volcano. ... Read all
