Mt Redoubt Erupts – And Erupts Again

24 03 2009

From the USGS: Since Sunday, March 22, at approximately 22:38 AKDT, Alaska Redoubt Volcano has erupted six times. The explosive eruptions that each lasted from four to thirty minutes, caused melting of the Drift glacier and greatly increased discharge down the Drift River.

National Weather Service radar, pilot reports, and AVO analysis of satellite imagery suggest that these events produced ash clouds that reached 60,000 ft above sea level (asl), with the bulk of the ash volume between 25 – 30,000 ft asl.

A sixth explosive eruption occurred at 7:41PM AKDT. Clear web camera views show that the ash emission has ended. Steaming is visible from the summit. The National Weather Service has posted a new ashfall advisory:

The alert level warming remains at RED.

Louisiana Governor Bobby Jindal was not available for comment.
