ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Monday, October 5, 2009, 1:11 PM AKDT (Monday, October 5, 2009, 21:11 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
Clear satellite views this morning revealed no signs of volcanic activity at Cleveland. A brief eruption at approximately 2330 AKDT October 2 (0730 UTC October 3) 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,
