Tungurahua volcano (Ecuador): increasing activity and new pyroclastic flow

Thursday Dec 20, 2012 11:05 AM | BY: T

An explosion at 01:50 (local time) this night was followed by an increase of seismic and visible activity. Between 02:00 and 04:00 am, explosions followed at intervals of only 5 minutes and produced loud cannon-shot noises and shock waves, and ejected incandescent blocks of various sizes.
At 02:30, a pyroclastic flow ran down the Cusua ravine, and strong ash fall was reported from Penipe.

The activity today was characterized by numerous explosions of moderate size with loud gun-shot noises and roars heard in all towns near the volcano. Some of the explosions caused buildings vibrate. Continuous volcanic tremor was measured and localized at depth of 3-4 km beneath the crater. During the night, glowing bombs were seen ejected 3-400 m above the crater and rolling down for about 1 km on the volcano's slopes. ... [more]

Wednesday, Dec 19, 2012
Tungurahua continued to produce a sustained ash column rising 2-3 km and intermittent stronger explosions. Several pyroclastic flows occurred yesterday (at 05:00 am, 07:47 and 15:30 local time), the one at 07:47 reaching a length of up to 4 km distance near La Hacienda. The deposits of the flows were reported seen in the gorge and reaching the plain in the area between the Mandur and La Hacienda. ... [more]

During last night and early today explosions and volcanic tremor continued to be recorded. Pulsating lava fountains and strong strombolian-type ejections of incandescent blocks were observed at night with fountains reaching a height of 1 km and bombs landing on the upper cone. In the morning, a small small pyroclastic flow descended through the gorge of La Hacienda. ... [more]

During the night 16-17 Dec, some strong explosions occurred that could be heard as far as Pillaro and Salcedo. Medium to strong levels of tremor and emission signals were recorded on the seismographs. Incandescent blocks were seen ejected about 200 m above the crater and landing on the upper flanks. ...

Monday, Dec 17, 2012
Following the first explosion on Friday, the volcano has entered a second violent phase of activity on Sunday. Numerous explosions have occurred in the morning of Sunday with ash rising up to 8 km above the crater. Small pyroclastic flows have descended the flanks and partly heavy ash fall has been affecting nearby areas. Combined with rainfall the fresh ash deposits have a dangerous potential to generate lahars in drainages surrounding the volcano. ... [more]
