AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Saturday, July 26, 2008, 2:57 PM AKDT (Saturday, July 26, 2008, 22:57 UTC)


OKMOK VOLCANO (VNUM #311290)
53°23'49" N 168°9'58" W, Summit Elevation 3520 ft (1073 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The amplitude and duration of seismic activity has decreased since yesterday. Satellite data indicate ash is rising to 20,000 to 22,000 feet. As a result of the decreased seismicity, AVO lowered the Aviation Color Code and Volcano Alert Level from RED/WARNING to ORANGE/WATCH this morning at 11:01 AM AKDT.

Stronger explosive activity could resume at any time with little or no warning.

Despite cloudy conditions, thermal anomalies seen in satellite views today suggest the presence of lava on the surface near Cleveland's summit.
