ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Wednesday, May 6, 2009, 3:12 PM AKDT (Wednesday, May 6, 2009, 23:12 UTC)
60°29'7" N 152°44'38" W,
Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
The 2009 eruption of Redoubt continues. Seismicity at the volcano has intensified in the last 24 hours, with nearly continuous small earthquakes now being recorded near the summit. Steam emissions have become increasingly vigorous over the last 24 hours. Satellite data from this morning show minor ash components in plume emissions. Rockfalls also continue to trigger ash emissions near the summit.
At approximately 22:00 AKDT on May 5 (0600 UTC May 6), there was a distinct increase in seismicity, with a near doubling in the intensity of volcanic tremor and a notable increase in the number of discrete events. At the same time, steam emissions greatly intensified and were briefly accompanied by vigorous ash emissions that did not exceed 12,000 feet above sea level.
AVO is monitoring the situation closely and the observatory is staffed 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.
