AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Wednesday, May 20, 2009, 1:58 PM AKDT (Wednesday, May 20, 2009, 21:58 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 2009 eruption of Redoubt continues. Seismicity over the past 24 hours remains elevated, and the summit lava dome continues to grow. Webcam views are partially obscured by clouds today, but it is likely that low level steam and gas emissions are continuing. Rock fall activity continues on the unstable slopes of the lava dome, producing minor ash clouds in the vicinity of the summit. No ash has been detected by satellite or radar data however. The lava dome may become unstable and could collapse with little or no warning, leading to significant ash emissions and possible lahars in the Drift River Valley.

AVO is monitoring Redoubt volcano closely and the observatory is staffed 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.


VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Volcanic tremor continues at Veniaminof. Satellite data were mostly cloudy during the past 24 hours. No unusual activity has been reported.
