AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, April 9, 2009, 1:03 PM AKDT (Thursday, April 9, 2009, 21:03 UTC)


REDOUBT VOLCANO (VNUM #313030)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption of Redoubt continues. Seismic and satellite data over the past day indicate continued lava dome growth. Satellite and web camera images have been obscured by clouds, but no significant ash emissions visible in radar. A satellite image from yesterday afternoon showed a continuous sulfur dioxide gas plume extending for more than 600 miles from volcano.

Additional significant explosive events with accompanying ash clouds, ash fall, and mudflows are possible and can occur with little or no warning. AVO will maintain 24/7 operations in order to quickly detect renewed significant explosive activity and other hazardous phenomena.

Please see the National Weather Service Redoubt coordination page http://pafc.arh.noaa.gov/volcano.php for the latest ash fall information.
