ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, September 11, 2011, 1:03 PM AKDT (Sunday, September 11, 2011, 21:03 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
Over the past 24 hours, clouds have obscured satellite views of Cleveland. No other new reports have been received regarding the volcano.
The latest episode of dome growth began around September 3. A growing lava dome in the crater increases the possibility of an explosive eruption, but does not necessarily indicate that one will occur. Short-lived explosions could produce ash clouds that exceed 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours.
Without a real-time seismic network on the volcano, AVO is unable to track local earthquake activity related to volcanic unrest, provide forecasts of eruptive activity, or confirmation of explosive, ash-producing events. AVO will continue to monitor the volcano using satellite data as it becomes available.
