Tungurahua volcano (Ecuador) activity update: continuing explosions

Wednesday Dec 19, 2012 21:05 PM | BY: T

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.
Constant ash emissions reached heights between 2 and 2.5 km above the crater. The ash plume was directed mainly towards the south-west, and ash falls occurred in Choglontus, Cahuaji, Manzano, Palitahua, El Altar, Puela, La Matriz, El Rosario, Santa Fe de Galán, San José de Chazo, Guanando and Ilapo.
Deformation measurements indicated a continued inflation. On the other hand, gas emission measurements were relatively moderate (1385 ton / day of SO2) compared to previous eruptive episodes. Given that emission column address has varied frequently since the start of the eruptive process, this value may be underestimated.
The ash emitted during these days is composed of new or juvenile magmatic material, and the whitish color is due to high glass content.

From these data, IG thinks that the most likely scenario is that there is a relatively large volume of magma which is rising slowly. For this reason, it is expected that explosions and ash emissions will continue for a while. New pyroclastic flows must be expected as well.

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]
Explosion on 14 Dec 2012
Friday, Dec 14, 2012
A sudden strong ash explosion occurred at Tungurahua volcano in Ecuador today at 14:35 local time. According to local reports, the eruption produced an ash plume rising to 6 km altitude and was visible from Ambato, Riobamba, Pelileo and Patate. The explosion followed an increase in seismicity over the past days. [more]
