Tungurahua volcano (Ecuador) activity update: steaming, weak seismic activity
Wednesday Oct 03, 2012 10:05 AM | VON: T
Activity remains low at the volcano which is almost constantly covered in clouds.
Current seismic signal from RETU station (IG)
Only few quakes and long-period events are recorded, but there are no reports of explosions and no significant SO2 emissions were visible on recent satellite data.

Seismicity at the volcano remains moderate to low. Direct observations of summit activity are hindered by near constant cloud cover, but there are no indications of recent explosions or ash emissions. [mehr]

Visual observations are near impossible due to constant cloud cover, but the seismic activity, described as moderate by IG, does not indicate significant eruptive activity. [mehr]

A possible small ash emission was reported by VAAC Washington at 14:16 GMT today. No ash is visible on satellite images, and the seismic signal is very quiet with only a few small volcanic earthquakes. [mehr]

Activity at the volcano has remained low. Steaming could be observed during windows of clear weather, and there are numerous long-period seismic events recorded. [mehr]

After the sharp increase in volcanic gas emissions (SO2) and abundant presence of seismic signals related to internal movement of fluids recorded earlier this month of September, activity from Tungurahua volcano has declined markedly since 4 September and presently has seismicity with moderate to low levels, and occasionally some small steam emissions. A drastic reduction in SO2 emission rates recently is one of the most significant observations. ... [mehr]
