ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, May 17, 2012, 11:34 AM AKDT (Thursday, May 17, 2012, 19:34 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 was observed in web camera and satellite images over the past 24 hours. AVO has received no reports of 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
Nothing unusual was observed in satellite data of Cleveland Volcano over the past 24 hours. No ash emissions detected or reported.
While Cleveland Volcano is active, sudden ash-producing explosions are possible at any time. Associated ash clouds could extend to more than 20,000 feet above sea level. If a large ash-producing eruption 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.
