ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Saturday, February 26, 2005 3:55 PM AST (Feb 27 0055 UTC)



ALASKA VOLCANOES WITH ELEVATED COLOR CODES:



MOUNT VENIAMINOF VOLCANO (CAVW #1102-07)

5610'N 15923'W, Summit Cone Elevation 7,073 ft (2,156 m)

Current Level of Concern Color Code: YELLOW



Seismicity at Veniaminof volcano has remained near background levels over

the past 24 hours. The volcano has been visible by Internet camera in

Perryville, but nothing of note has been observed. Clear satellite views of

the volcano have been possible today but no thermal anomalies or other

activity was observed. Although activity has diminished, low-level

explosions of steam and ash similar to those observed over the past month

could resume and these may pose a hazard to people and low flying aircraft

in the vicinity of the active cone.



MOUNT SPURR VOLCANO (CAVW#1103-04)

6118' N 15215' W, Summit Elevation 11,070 ft (3,374 m)

Current Level of Concern Color Code: YELLOW



Elevated levels of seismicity continue much as they have for the past

month. Good views of the volcano in satellite and Internet camera images

were possible throughout the day but no activity was observed. There are no

indications that an eruption is imminent.



KOROVIN VOLCANO (Atka volcanic center-CAVW #1101-16)

52.381 N 174.154 W, Summit Cone Elevation 5,029 ft (1,533 m)

Current Level of Concern Color Code: YELLOW



AVO has received no new information or observations on the status of

Korovin volcano. Volcanic emissions from Korovin such as ash bursts and

drifting ash clouds could pose a hazard to people and low flying aircraft

in the vicinity of the volcano and light ash fall on parts of Atka Island,

including the village of Atka may occur. There are no indications that a

large eruption is imminent.

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.
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].
