Big Boom- but we're okay

2009-03-26 12:38:35
A large eruption of Redoubt volcano occurred at 09:24 AKDT (17:24 UTC) this morning. National Weather Service reports the cloud height to be at least 65,000 ft above sea level and pilot reports indicated a plume height of 60,000 ft. Since this event, a few smaller events have occurred but these did not generate plumes above about 20,000 feet.

The eruption at 9:24 AKDT also produced a lahar in the Drift River valley that was detected by seismic instruments.

An ashfall advisory is in effect until 4 PM for the western Kenai Peninsula. High level ash (above 30,000 feet) is forecast to pass over Anchorage, but is not expected to produce ash fall. For more information refer to the NWS Redoubt Coordination web page (http://pafc.arh.noaa.gov/volcano.php) for latest ash cloud information.

AVO is monitoring the situation closely, the observatory is staffed 24/7, and attempts to overfly the volcano will occur as soon as possible. More details on this mornings eruption also will be released on AVO's web page as soon as possible.

Guess it is coming after all...
