Cleveland Volcano Activity Notifications 2009-10-03 11:16:20 - Status Report
Satellite data indicate that Cleveland volcano erupted briefly this morning at ~0730 UTC (2330 AKDT) 02 October 2009, producing a small, detached ash cloud that drifted northeast of the volcano at maximum altitudes of 15,000' to 20,000' (4.5 - 6.1 km) . AVO increased the aviation color code to Orange, and the volcano alert level to Watch at 02:29 AKDT (10:29 UTC) this morning. Satellite views until about 6:45 AKDT (14:45 UTC) show that the ash cloud drifted northeast about 600 km (373 mi) and dispersed over the Bering Sea. While no more events have been detected this morning, further eruptive activity is possible.
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 with ash plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery.
