ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Wednesday, February 23, 2005 3:40 PM AST (Feb 24 0040 UTC)
ALASKA VOLCANOES WITH ELEVATED COLOR CODES:
MOUNT VENIAMINOF VOLCANO (CAVW #1102-07)
56°10'N 159°23'W, Summit Cone Elevation 7,073 ft (2,156 m)
Current Level of Concern Color Code: ORANGE
Seismicity at Veniaminof volcano has remained at relatively low levels over
the past 24 hours. Long periods of little or no seismicity and occasional
short intervals of tremor or discrete events characterize the present
activity. The volcano has been occasionally visible by internet camera in
Perryville, but nothing of note has been observed. Clouds have obscured
satellite views of the volcano throughout the day. Although activity has
diminished somewhat, Strombolian explosions of steam and ash similar to
those observed over the past month can occur at any time.
At the present level of activity, we do not expect ash to rise much more
than 13,000 ft (4,000 m) above sea level. Ash bursts and drifting ash
clouds could pose a hazard to people and low flying aircraft in the
vicinity of the active cone. Very light ash fall with little accumulation
outside of the summit caldera is also possible. There are no indications
that a larger eruption is imminent.
MOUNT SPURR VOLCANO (CAVW#1103-04)
61°18' N 152°15' 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
several weeks. Clouds obscured the volcano in web camera and satellite
views. There are no indications that an eruption is imminent.
