AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, August 2, 2009, 1:20 PM AKDT (Sunday, August 2, 2009, 21:20 UTC)


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

No significant changes have been observed at Redoubt volcano over the past 24 hours. Seismicity remains low. Webcam views have been mostly obscured by clouds. The dome remains potentially unstable, and its collapse would likely result in significant ash production, hot block and ash flows, and flooding in the Drift River valley. Although the operations center is no longer staffed 24/7, AVO continues to monitor the volcano on a 24/7 basis using an alarm system that alerts on-call staff of potential activity.

SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Clouds have obscured satellite images of the volcano over the last 24 hours. Seismic and deformation data show nothing abnormal at the volcano, and there is currently no indication that an eruption will occur. Minor steaming is expected to be ongoing, which is typical behavior for this volcano. AVO will continue to closely monitor activity at Shishaldin.
