ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, February 23, 2012, 11:31 AM AKST (Thursday, February 23, 2012, 20:31 UTC)
51°55'27" N 177°9'44" W,
Summit Elevation 4288 ft (1307 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
No unusual activity was detected in seismic data or cloudy satellite data at Kanaga in the past 24 hours. AVO has received no reports of explosive activity or ash clouds.
The possibility remains for sudden explosions of ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. If a large, explosive, ash-producing event occurs, the local seismic network, satellite ash alarms, infrasound, and volcanic lightning will alert AVO to the new activity.
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
A thermal anomaly was visible through cloudy satellite views of Cleveland volcano over the past 24 hours. AVO received no other reports of unusual activity.
It remains possible for intermittent, sudden explosions of blocks and ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours. If a large, explosive, ash-producing event occurs, seismic, infrasound, or volcanic lightning may be detected by local and regional monitoring networks. There is no real-time seismic monitoring network on Mount Cleveland.
