ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORT
Monday, March 30, 2009 11:56 AM AKDT (Monday, March 30, 2009 19:56 UTC)


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

Over the past twelve hours, ash emissions at Redoubt Volcano have become more frequent, but lower in altitude than during the highly explosive events of the past week. A continuous ash plume has been observed in web camera, satellite and radar images, and by pilots. These plumes vary in their intensity and have generally been at low altitude (less than 20,000 feet above sea level). Occasional, short lived events have produced ash clouds that rise as high as 27,000 feet above sea level. Ash fall from these events is currently not likely to reach population centers in the Cook Inlet. 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 week. Clear satellite views show nothing unusual.

NORMAL
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
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.
AVIATION COLOR CODES
GREEN
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
YELLOW
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.
ORANGE
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
RED
Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere [ash-plume height specified, if possible].
