ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Tuesday, April 3, 2012, 12:56 PM AKDT (Tuesday, April 3, 2012, 20:56 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. Clear views by web camera and satellite over the past 24 hours show no unusual activity.
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
Elevated surface temperatures were observed in satellite images of Cleveland Volcano today. This is consistent with the hot lava dome in the summit crater reported on March 28, 2012 . AVO has received no other reports of activity at the volcano.
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.
