ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Monday, January 24, 2005 3:50 PM AST (January 25, 00:50 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 remains at elevated levels, similar to what has been observed
over the last several days. Several episodes of low-level tremor bursts
have been recorded over the past 9 hours. Clear web camera views earlier
in the day showed intermittent steam and ash emissions; clouds have
obscured the view this afternoon. Satellite imagery showed heat anomalies
at the summit cone throughout the night and morning. Based on seismic
signals and web camera views, we infer that small ash emissions, generally
reaching elevations less than 12,000 ft above sea level, have been
occurring sporadically throughout the day.
We expect steam and ash emissions to continue and these could pose a hazard
to people and low flying aircraft in the vicinity of the active cone.
Small ash falls outside of the summit caldera are possible.
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.
Clouds obscured web and satellite views today. There are no indications
that an eruption is imminent.
