Alaska Volcano
DHS&EM along with Alaska Volcano Observatory and the National Weather Service staff are closely monitoring Redoubt Volcano.  

Redoubt Volcano
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Alaska Volcano Observatory’s Current Status Report: 26 Feb 09 1:19 PM
Unrest at Redoubt Volcano continues. No eruption has occurred.

Beginning yesterday afternoon at 3:37 PM AKST, tremor amplitude increased sharply and remained elevated for approximately one hour. At 4:14 PM AKST, the tremor amplitude briefly matched the highest amplitude seen during the current episode of unrest. This tremor was strong enough to be recorded on all seismic stations on Redoubt Volcano as well as many stations surrounding Cook Inlet. Since that time, tremor amplitude has decreased significantly. Last night around 10:40 PM AKST, the number of discrete earthquakes increased and remained elevated until about 2:55 AM AKST today. Preliminary analysis of these earthquakes indicate they are occurring at shallow depth (1 to 3 km) below the summit crater of Redoubt. Since that time, discrete events are continuing at a lower rate, and tremor levels remain low. These variations in the character of seismic activity indicate that conditions have changed at shallow depths beneath the volcano. AVO is currently analyzing this seismic activity and will issue further information as it becomes available.

An observation flight to the volcano is currently underway. Winds are too high at the volcano to perform gas measurements today.

A small steam plume is visible in clear HutCam images today.

AVO continues to monitor Redoubt Volcano closely, and the observatory is staffed 24 hours a day.
