Tungurahua volcano (Ecuador) activity update: steaming, small explosions

Monday Sep 03, 2012 12:05 PM | BY: T

Current moderate tremor signal (RETU station) spectrogram (IG)
Current moderate tremor signal (RETU station) spectrogram (IG)
Seismic activity has increased since the beginning of the month again, however not reached previous levels and IG describes it at moderate. Surface activity have been mainly steaming, creating a 300 m high plume, and few weak explosions, causing light ash fall.

Since the beginning of this week Tungurahua's seismic activity was characterized by internal fluid movements (LP events) and volcano-tectonic earthquakes (VT) (rock fracturing within the volcanic edifice). There were 8 quakes under the northwestern flank of Tungurahua at depths between 3-13 km below the summit. It is worth noting that some of these events were felt by residents of CUSU, Juive Grande, Puntzán and Bathrooms in the evening of 26 August at 20h26 (local time) and on 29 August at 18h46 (local time) and 30 August at 09h32 (local time). These local events had magnitudes between 2.5 and 2.6. The other quakes were only recorded instrumentally. ... [more]

Tremor remains at fluctuating moderate levels. Bad weather prevents visual observation of steam and possible ash emissions and explosions. [more]

A rising tremor signal suggests ongoing ash emissions and small explosions, but bad weather prevents observations. The recent moderate rain falls have fortunately not caused lahars, IG mentions. [more]
