Issued: Monday, July 21, 2008, 2:16 PM AKDT

Volcanic Activity Summary: Reports from fishing boats indicate an eruption of Cleveland volcano occurred at approximately 12:00 AKDT (20:00 UTC). These reports indicate that at sea level the ash may be moving to the northwest. AVO has no information about the height of the ash cloud at this time.

Remarks: 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.
