ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, November 6, 2012, 11:26 AM AKST (Tuesday, November 6, 2012, 20:26 UTC)

CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Mostly cloudy satellite views detected elevated surface temperatures early this morning. Clouds obscured web camera views over the past day. AVO has received no reports of unusual activity at the volcano.

Sudden explosions of blocks and ash remain possible with little or no warning. 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 (VNUM #313020)
60°1'55" N 153°5'30" W, Summit Elevation 10016 ft (3053 m)

Seismicity remains somewhat elevated. Nothing unusual observed in mostly clear satellite and web camera images over the past day. AVO has received no reports of activity at the volcano.
