ALASKA VOLCANO OBSERVATORY DAILY UPDATE
Monday, October 1, 2012 12:01 PM AKDT (Monday, October 1, 2012 20:01 UTC)


LITTLE SITKIN VOLCANO (CAVW #1101-05-)
51°57'11" N 178°32'8" E, Summit Elevation 3898 ft (1188 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismic activity remains elevated. Nothing unusual was observed in mostly cloudy satellite images over the past 24 hours. AVO has received no reports of unusual activity at the volcano.

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

Nothing unusual was observed in mostly cloudy satellite data or web camera views of the volcano over the past 24 hours. No other activity has been reported.

Sudden explosions of blocks and ash remain possible with little or no warning, although the last confirmed explosion occurred on August 20. Ash clouds, if produced, could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby seismic, infrasound, or volcanic lightning networks should alert AVO staff quickly. However, for some events, a delay of several hours is possible. There is no real-time seismic monitoring network on Mount Cleveland and 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

Seismicity remains slightly above background. Clear web camera and satellite views show nothing unusual over the past day. AVO has received no reports of unusual activity at the volcano.
