ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Sunday, January 30, 2005 3:55 PM AST (January 31, 0055 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 the webcam view today as
well as satellite views. Based on seismic signals, 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.
Seismic activity has remained at roughly the same level since the increase
noted 2 days ago. No activity was observed in clear views of the volcano
from satellite and web camera images. There are no indications that an
eruption is imminent.
