ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORT
Thursday, March 29, 2012 11:47 AM AKDT (Thursday, March 29, 2012 19:47 UTC)


CLEVELAND VOLCANO (CAVW #1101-24-)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Clouds obscured satellite views of Cleveland Volcano over the past 24 hours. AVO has received no new 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.

ILIAMNA VOLCANO (CAVW #1103-02-)
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. Clouds obscured web camera and satellite views over the past 24 hours.

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.
