ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Monday, April 16, 2012, 2:52 PM AKDT (Monday, April 16, 2012, 22:52 UTC)
60°1'55" N 153°5'30" W,
Summit Elevation 10016 ft (3053 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Seismic activity at Iliamna Volcano remains slightly above background. Nothing unusual observed in web camera and satellite images over the past day.
The current activity at Iliamna does not indicate an imminent or certain eruption. A similar seismic swarm at Iliamna in 1996-1997 was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a further increase in earthquake 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
There has been no evidence of explosive activity or eruption of lava in the summit crater over the past day. Although conditions have been mostly cloudy, a possible weak thermal anomaly was detected in a satellite image today.
While the volcano remains active, sudden explosions of blocks and ash are likely. It is possible for associated ash clouds to exceed 20,000 feet above sea level. If a larger ash-producing event occurs, seismic, infrasound, or volcanic lightning networks should detect the event and alert AVO staff. There is no real-time seismic monitoring network on Mount Cleveland so AVO is unable to track activity in real time.
