AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, June 28, 2009, 1:41 PM AKDT (Sunday, June 28, 2009, 21:41 UTC)


CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

A small eruption at Cleveland volcano occurred Thursday, June 25, producing an ash plume that rose to less than 15,000 ft. above sea level. The plume, observed in satellite images, quickly detached from the volcano and moved south. There have been no further reports of activity. Such small, short-lived events are typical of Cleveland volcano.



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

Eruptive activity at Redoubt may be continuing at a low level. Seismicity remains slightly above background level. Webcam images show continued steaming from the lava dome at the summit. No ash signals have been observed in radar or satellite data.

The growth rate of the lava dome has significantly slowed. It is still possible that this large mass of fresh lava is unstable and could fail with little or no warning, leading to significant ash production and possible lahars in the Drift River valley.

AVO continues to monitor Redoubt's activity 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazards.
