Redoubt volcano: news & activity updates

Redoubt volcano (Alaska), eruption news: large explosions (22-23 March 2009)

Monday Mar 23, 2009 14:19 PM |

After about two days of increasing seismicity, a large plinian or sub-plinian explosive eruption is in course at Mt. Redoubt volcano; .
It follows a period since late last year of gradually increasing activity, and a short-term period of seismic swarms related to rock failure due to increasing pressure and the rise of the magma. The eruption is being closely monitored by USGS staff from the Alaska Volcano Observatory (AVO).
From their rapidly succeeding reports:

"An eruption of Mt Redoubt began at approximately 22:38 AKDT, March 22, 2009 (0638 UTC). AVO is raising the aviation color code to Red and the alert level to Warning... Current estimate for eruption cloud height are 50,000 ft above sea level. (2009-03-22, 23h20:21 local time)...

As of 2:00AM March 23, 2009, AVO has recorded FOUR large explosions at Redoubt volcano at the following times:
March 22 10:38PM
March 22 11:02PM
March 23 12:14AM
March 23 01:39AM
The National Weather Service has issued an Ashfall Advisory. Link: pafc.arh.noaa.gov/volcano.php

Friday, Jan 30, 2009
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. [more]
Saturday, Nov 08, 2008
The Alaska Volcano Observatory has changed the volcano alert level for Redoubt Volcano to advisory, with an aviation code level of yellow. In a notice issued Wednesday, AVO said it changed the alert level due to changes in gas emission and heat output from the volcano. The recent changes are different from background activity. [more]
