lundi mars 16, 2009 18:11 |
A medium-sized eruption has occurred at Redoubt volcano, Alaska, the USGS / Alaska VolcanoObservatory (AVO) reports. Seismic activity had increased markedly since Sunday afternoon (March 15, 2009) and was followed by 4 hours of continuous volcanic tremor.
The onset of the tremor was associated with a small explosion that produced a plume of gas and ash that rose to about 15,000 feet above sea level and deposited a trace amount of ash over the summit-crater floor and down the south flank of the volcano to about 3,000 feet.
AVO notes that "at this time it does not appear that the increase in activity heralds a significant eruption in the short term, but conditions may evolve rapidly."

The volcano Redoubt in Alaska is very close to an eruption. The Alaska Volcano Observatory reports that there are increasing seismic levels. Until now there is no eruption visible. The staff of the observatory is watching the volcano on a 24 hours base. The alert level is at orange, what is a serious sign for a near eruption. The ice covered volcano may cause lahars and later eventually even pyroclastic flows (?). The situation is surely dangerous after the experience USA made with Mt. St. Helens. [details]
