Tungurahua volcano news & eruption updates:

Tungurahua Volcano: explosions, ash fall and possible pyroclastic flow

Sunday Mar 04, 2012 20:39 PM | BY: T

Ecuador's Instituto Geofísico (IG) reports an increase of Tunguarahua volcano's activity: Since last night (3 March), 4 explosions have been reported of moderate to large size. An explosion at 07:31 local time today produced an ash columnreaching about 4 km in height and drifting to the west - northwest.
A second explosion took place at 09:11 (local time) and produced a strong shock wave that rattled the ground and windows in nearby areas. CLoud cover has prevented detailed observations, but with the help of thermal sensors, hot fresh deposits were detected on the flanks, suggesting they were the result of a pyroclastic flow.
In the morning, the observatory post at Cusúa reported the presence of hot deposits on the upper flank typical for fresh pyroclastic flow deposits.
Ash fall was reported from Choglontús, Manzano and Motilones areas before, and this morning ashfall reached the Yuibug area.
The monitoring system has been recording variable seismicity and powerful tremor episodes lasting minutes to hours (which probably indicate rising magma), interrupted by short moderate to large explosion signals corresponding to the ash eruptions from the growing lava dome.
