ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, March 22, 2009, 1:49 PM AKDT (Sunday, March 22, 2009, 21:49 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
AVO raised the aviation color code to Orange and the alert level to Watch last night at 10:09PM AKDT (March 21) based on an increase in the rate of discrete seismic events. Shallow earthquake activity under the volcano has been as high as 26 events per 10-minute period. Activity is primarily seen on the stations nearest the summit, though some events are also recorded at farther-out stations. This activity likely represents either the upward movement of magma or pressurization of the system. No eruption has occurred.
It is possible for unrest at the volcano to change rapidly, and seismic activity or other signs of unrest could escalate culminating in an eruption within days to weeks.
