ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Monday, January 17, 2005 3:40 PM AST (January 18, 00:40 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
Elevated levels of seismicity continue to be recorded beneath Mount
Veniminof. Short tremor bursts, characteristic of past ash emissions, are
visible in the seismic record. Clouds continue to obscure the active vent
in satellite data and web camera images. Based on the seismic signals, 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 steam and ash emissions to 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.
No activity was visible in clear web camera and satellite data. There are
no indications that an eruption is imminent.
