AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, November 15, 2012, 12:47 PM AKST (Thursday, November 15, 2012, 21:47 UTC)


CLEVELAND VOLCANO (VNUM #311240)
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 activity was observed in mostly cloudy satellite and webcam views over the past 24 hours. AVO has received no reports of activity at the volcano.

Sudden explosions of blocks and ash remain possible with little or no warning. The previous confirmed explosion occurred on November 10. 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.
