Alaska Asset Team Update: Mt Redoubt Alert Level at Orange (3-15-09)
The following is an update from the Alaska Volcano Observatory Web site (http://www.avo.alaska.edu/)
Redoubt Volcano Activity Notifications 2009-03-15 14:50:14 - VAN/VONA
Seismic activity at Redoubt has increased since about 13:00 AKDT and is continuing. An AVO observation flight reported that a steam and ash plume rose as high as 15,000 ft above sea level and produced minor ash fall on the upper south flank of Redoubt. Last reports are that the plume is now mainly steam.
Based on this change in activity AVO is increasing the level of concern and alert level to ORANGE/WATCH.
It does not appear at this time that a significant eruption is likely in the short term, but conditions may evolve rapidly.
AVO is monitoring the situation closely and the AVO operations center in Anchorage is now resuming 24 hour per day staffing.
