ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Tuesday, January 18, 2005 3:00 PM AST (January 19, 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. Web camera images show some low-level ash
emissions, though the view is partially obscured by clouds. Satellite
imagery from this morning shows anomalous heat near the summit cone. Based
on seismic signals and the limited web view, we infer that small ash
emissions, reaching elevations less than 12,000 ft above sea level, have
been occurring sporadically throughout the day.
We expect that steam and ash emissions may continue and 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.
Clear views of the volcano in web and satellite imagery show no anomalous
activity. There are no indications that an eruption is imminent.
