ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Friday, February 4, 2005 3:35 PM AST (February 5, 0035 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
After a decrease in seismic activity through the early morning, seismicity
at Mount Veniaminof picked up and is again at a level similar to last night
when strombolian activity, or ejection of hot blocks and lava, was clearly
visible to residents of Perryville, 30 km (22 miles) from the volcano. The
eruption was also visible in web camera views and seen by satellite as an
increase in surface temperature. We do not expect that this current
activity will put ash into the air above 13,000 ft (4,000 m) above sea
Low-level strombolian activity that ejects blocks of hot rock and lava
could occur with little or no warning, though the ejecta would stay within
the summit caldera. We expect steam and ash emissions to continue and could
pose a hazard to people and low-flying aircraft in the vicinity of the
active cone. Light ash falls outside of the summit caldera are 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 to be recorded beneath Mount Spurr.
The volcano was clear in web camera and satellite views today and showed
nothing unusual. There are no indications that an eruption is imminent.
