ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, October 4, 2009, 1:32 PM AKDT (Sunday, October 4, 2009, 21:32 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Clouds have obscured Cleveland volcano in satellite data today. No additional eruptive activity has been observed. A brief eruption at ~0730 UTC (2330 AKDT) 02 October 2009 produced a small, detached ash cloud at maximum altitudes of 15,000' to 20,000' (4.5 - 6.1 km). While no more events have been detected, further eruptive activity is possible at any time.
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.
54°45'19" N 163°58'16" W,
