ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Friday, January 21, 2005 3:00 PM AST (January 22, 00:00 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. Clouds have obscured web camera and satellite
views today. Based on seismic signals, we infer that small ash emissions,
generally reaching elevations less than 10,000 ft above sea level, have
been occurring sporadically throughout the day. Particularly strong bursts
of seismic tremor at ~05:00 and ~22:00 UTC today may have been associated
with slightly higher plumes, but still less than 13,000 ft above sea level.
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.
