ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Sunday, January 23, 2005 2:00 PM AST (January 23, 23:00 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. Clear web camera views showed intermittent
low-level steam and ash emissions from dawn until about 11:15 AM today;
clouds have obscured the view since then. 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.
