ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Wednesday, June 27, 2012, 11:46 AM AKDT (Wednesday, June 27, 2012, 19:46 UTC)
ILIAMNA VOLCANO
(VNUM #313020)
60°1'55" N 153°5'30" W,
Summit Elevation 10016 ft (3053 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code:
YELLOW
Cloudy conditions obscured satellite views of Iliamna in the past 24 hours. No other observations of activity have been reported.
The current level of activity at Iliamna does not indicate an imminent or certain eruption and seismic activity appears to be declining gradually. A similar seismic swarm occurred at Iliamna Volcano in 1996-1997 and was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a significant increase in earthquake activity beneath the volcano.
CLEVELAND VOLCANO
(VNUM #311240)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code:
ORANGE
Cloudy conditions obscured satellite views of the volcano over the past 24 hours, and there were no other reports of unusual activity.
Additional sudden explosions of blocks and ash are possible with little or no warning. It is possible for associated ash clouds to exceed 20,000 feet above sea level. If a large 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.
