ALASKA VOLCANO OBSERVATORY
CURRENT STATUS REPORT
Sunday, February 6, 2005 3:15 PM AST (February 7, 0015 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
Occasional discrete seismic events associated with steam and ash emissions
continue to be recorded, but low-level tremor and wind noise now dominate
the seismic record. Clouds obscured the volcano in web camera images.
Satellite data continue to show increased surface temperatures. We expect
steam and ash emissions to continue that could pose a hazard to people and
low flying aircraft in the vicinity of the active cone. Such emissions
should be similar to what we have seen earlier and not exceed 13,000 ft.
(4000 m) above sea level. Low-level strombolian activity that ejects hot
blocks and lava several hundred meters above the intracaldera cone similar
to what was seen Thursday night could resume with little or no warning.
Small ash falls outside of the summit caldera are possible. There are no
indications that a larger eruption is imminent.
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.
The volcano was clear in web camera and satellite views today and showed
nothing unusual. There are no indications that an eruption is imminent.
