AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, July 26, 2009, 2:33 PM AKDT (Sunday, July 26, 2009, 22:33 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. Clouds continue to obscure satellite and web camera images. The 2009 lava dome remains potentially unstable, and its collapse would likely result in significant ash production, block and ash flows, and flooding in the Drift River valley. AVO continues to closely monitor Redoubt's 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

Satellite passes with favorable viewing conditions continue to show thermal anomalies at the summit of Shishaldin. Seismic and deformation data do not show anything 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.
