ALASKA VOLCANO OBSERVATORY DAILY UPDATE
Wednesday, October 24, 2012 10:47 AM AKDT (Wednesday, October 24, 2012 18:47 UTC)


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

Clouds obscured views of the volcano by satellite over the past 24 hours. Elevated surface temperatures were observed in satellite data today. AVO has received no other 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 (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 somewhat elevated. Clear web camera and satellite views of Iliamna show nothing unusual today. AVO has received no reports of activity at the volcano.
