Redoubt is back to Red/Warning status again after what the Alaska Volcano Observatory is calling a ‘significant explosive event’ at 06:00 AKDT today. The latest AVO bulletin (2009-04-04 06:58:38) reads as follows:

At 06:00 AKDT there was a significant explosive event at Redoubt. An ash cloud has reached at least 50,000 feet above sea level and is spreading towards the south and east. AVO seismometers indicate a lahar in the Drift River Valley.

AVO has upgraded the alert level to WARNING and aviation color code to RED.

This is a strong seismic event comparable to the events from March 23-28. Strong seismic activity is ongoing as of 07:01 AKDT.

There are some beautiful pictures of this activity from the Hut Webcam as the sun rises over Alaska. The pictures shown here were captured at 07:27 (above), and 07:40* and 08:10 (below) local time.
