ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, August 12, 2012, 12:34 PM AKDT (Sunday, August 12, 2012, 20:34 UTC)
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 views of Cleveland by satellite today. No other reports of activity have been received.
Sudden explosions of blocks and ash remain possible with little or no warning. Associated ash clouds could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby 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 and AVO is unable to track activity in real time.
60°1'55" N 153°5'30" W,
Summit Elevation 10016 ft (3053 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
No unusual activity has been observed or reported at Iliamna Volcano over the past 24 hours.
The current level of activity at Iliamna does not indicate an imminent or certain eruption. Seismic activity appears to be declining gradually. A similar seismic swarm occurred at Iliamna Volcano in 1996-1997 and was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a significant increase in earthquake activity beneath the volcano.
