ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, February 20, 2011, 12:18 PM AKST (Sunday, February 20, 2011, 21:18 UTC)
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 images of Cleveland volcano have been obscured by clouds in the past day. No reports of activity were received.
Without a real-time seismic network at Cleveland, AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash clouds that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery for hours. Low-level ash emissions at Cleveland occur frequently and do not necessarily mean a larger eruption is imminent. AVO continues to monitor the volcano using satellite imagery.
