ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORTSaturday, May 9, 2009 12:38 PM AKDT (Saturday, May 9, 2009 20:38 UTC)

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

The 2009 eruption of Redoubt continues. Seismicity at the volcano has declined over the past 48 hours, but still remains elevated. Vigorous steam and gas emissions are visible in web camera images. This plume may contain minor amounts of ash near the volcano, but no ash has been detected in satellite or radar data.

AVO is monitoring the situation closely and the observatory is staffed 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.

VENIAMINOF VOLCANO (CAVW #1102-07-)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Aviation Color Code: YELLOW
Current Volcano Alert Level: ADVISORY

Seismicity at Veniaminof remains elevated. In the past 24 hours AVO has observed small earthquakes and volcanic tremor located near the intra-caldera cone. These signals are seen across the entire seismic network. No unusual activity was observed through cloudy satellite views.

Volcano Alert Levels

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.

UNASSIGNED

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].
