ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Saturday, February 5, 2005 3:40 PM AST (February 6, 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
The discrete seismic events recorded during Thursday night’s activity have
diminished and tremor is now dominating the seismic record. No activity was
seen in web camera images last night, though that could have been the
result of cloudy weather. Satellite data continue to show increased
surface temperatures. We expect steam and ash emissions to continue that
could pose a hazard to people and low flying aircraft in the vicinity of
the active cone. Such emissions should be similar to what we have seen
earlier and not exceed 13,000 ft. (4000 m) above sea level. Low-level
strombolian activity similar to what was seen Thursday night could resume
with little or no warning. Small 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.
