Summary
John Power, a geophysicist with the U.S. Geological Survey Alaska Volcano Observatory points to a satellite image of the Mount Redoubt eruption pattern (green and purple on map) during a news conference, Anchorage, Alaska, 23 March, 2009.

A series of five eruptions that each lasted between four and thirty minutes (the last one ended at 5:00 AM AKDT 03-23-2009). Eye-witness accounts and satellite imagery analysis suggest ash clouds reached 60,000 feet above sea level (ft asl), with the bulk of the ash volume between 25 - 30,000 ft asl. Traces of ash fall have been reported in Skwentna, Talkeetna, Wasilla, and Trapper Creek.USGS
