ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, March 15, 2012, 12:24 PM AKDT (Thursday, March 15, 2012, 20:24 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 above background. This activity does not mean that an eruption is imminent or certain. A similar seismic swarm in 1996/1997 that was likely related to an intrusion of magma at depth did not culminate in an eruption.
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.
As long as the volcano remains active, additional explosions are likely. Some may produce ash clouds exceeding 20,000 feet above sea level. These clouds may go undetected in satellite imagery for hours. If a large ash-producing event occurs, seismic, infrasound, or volcanic lightning would likely be detected by local and regional monitoring networks. There is no real-time seismic monitoring network on Cleveland volcano.
