AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Tuesday, March 31, 2009, 1:48 PM AKDT (Tuesday, March 31, 2009, 21:48 UTC)


REDOUBT VOLCANO (VNUM #313030)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED

Continuous emissions of steam, volcanic gases, and minor amounts of ash continue at Redoubt Volcano, and have been visible in the Redoubt Hut web camera images throughout the day. These emissions have been generally been at low altitudes (less than 15,000 feet above sea level), but occasionally rise as high as 25,000 feet above sea level. Satellite images from this morning show a broad layer of volcanic haze extending east of the volcano over the Kenai Peninsula, the Anchorage Bowl, and the Matanuska-Susitna Valley. Satellite images from last night show a thermal anomaly at the vent and are possibly due to the extrusion of a lava dome in the summit crater. AVO field crews are attempting to make direct observations of the volcano today. Seismicity consists of volcanic tremor and occasional discrete earthquakes.

Please see the National Weather Service Redoubt coordination page http://pafc.arh.noaa.gov/volcano.php for the latest ash fall information.
