ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORT
Tuesday, April 14, 2009 11:51 AM AKDT (Tuesday, April 14, 2009 19:51 UTC)


REDOUBT VOLCANO (CAVW #1103-03-)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption of Redoubt volcano continues. Seismic data over the past day is indicative of continued lava dome growth. Clouds obscure views of the volcano by satellite and web cameras today. A low-level steam and gas plume that may contain small amounts of ash is likely present.

Additional significant explosive events with accompanying ash clouds, ash fall, and mudflows are possible and can occur with little or no warning. AVO will maintain 24/7 operations in order to quickly detect renewed significant explosive activity and other hazardous phenomena.

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

CLEVELAND VOLCANO (CAVW #1101-24-)
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 past 24 hours. Clouds obscure satellite views of the volcano today.

ADVISORY
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
WATCH
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.
WARNING
Hazardous eruption is imminent, underway, or suspected.
