ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Wednesday, July 16, 2008, 11:45 AM AKDT (Wednesday, July 16, 2008, 19:45 UTC)

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

Okmok Volcano continues to erupt. Over the last 24 hours, activity at Okmok has diminished. Seismicity has changed from nearly continuous volcanic tremor to a more episodic character, and over the last several hours, the overall seismic intensity has declined. The most recent satellite imagery indicates little or no ash, however weather clouds may be obscuring an ash signal.

Please see http://www.avo.alaska.edu/activity/Okmok.php for more information.

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

Satellite and webcam views remain cloudy. AVO has received no reports of eruptive activity at the volcano.

AVO monitors Cleveland Volcano with satellite imagery as weather allows. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions of ash that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery. Please see http://www.avo.alaska.edu/activity/Cleveland.php for more information.
