ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Saturday, March 17, 2012, 1:37 PM AKDT (Saturday, March 17, 2012, 21:37 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

Seismicity at Iliamna Volcano remains above background. The current activity does not indicate an imminent or certain eruption. A similar seismic swarm at Iliamna in 1996-1997 was not followed by eruptive activity.

A flight to the volcano to observe the summit area and measure volcanic gas emissions is in progress at this time.

A new AVO web camera looking at Iliamna can be accessed at this url:

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

No further explosions have been detected at Cleveland following the small afternoon event of March 13.

While the volcano remains in this active state, more 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.
