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

The 2009 eruption of Redoubt Volcano continues to produce emissions of steam, volcanic gases, and minor amounts of ash. The emissions have been visible in the Redoubt Hut web camera images throughout the day. Satellite data over the last few hours show a plume containing some ash extending about 40 miles east-northeast of Redoubt. These emissions have generally been at low altitudes (less than 15,000 feet above sea level). The plume may occasionally rise as high as 25,000 feet above sea level. T hermal features observed in satellite images and in AVO helicopter-based thermal-infrared images from yesterday are most likely due to the extrusion of a lava dome in the summit crater. 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.

52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

AVO has received no new reports of activity at Cleveland over the last 24 hours. Mostly cloudy views show nothing unusual.
