ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Thursday, September 8, 2005 3:50 PM AKDT (23:50 UTC)




ALASKA VOLCANOES WITH ELEVATED COLOR CODES:



MOUNT SPURR VOLCANO (CAVW#1103-04)

6118'N 15215'W, Summit Elevation 11,070 ft. (3,374 m)

Current Level of Concern Color Code: YELLOW



The level of seismic activity at Mt. Spurr volcano remains above background. The volcano has been visible in satellite and web camera views today. There are no indications that conditions at the volcano are changing or that an eruption is imminent.



VENIAMINOF VOLCANO (CAVW#1102-07)

56.2W 159.39N, Summit Elevation 8,225 ft. (2,507 m)

Current level of Concern Color Code: YELLOW



Several minor bursts of ash occurred at Veniaminof late yesterday afternoon that rose several hundred meters above the active cone and were confined to the caldera. Similar activity occurred in early 2005. Satellite and webcam views were obscurred today by clouds. Several minor events were observed in seismic records today similar to those produced yesterday. There are no indications that more vigorous activity is imminent or even likely.

VOLCANO ALERT LEVELS
NORMAL
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
ADVISORY
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
WATCH
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.
WARNING
Hazardous eruption is imminent, underway, or suspected.

AVIATION COLOR CODES
GREEN
Volcano is in typical background, noneruptive state or, after a change from a higher level, volcanic activity has ceased and volcano has returned to noneruptive background state.
YELLOW
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
ORANGE
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
RED
Eruption is imminent with significant emission of volcanic ash into the atmosphere likely OR eruption is underway or suspected with significant emission of volcanic ash into the atmosphere [ash-plume height specified, if possible].
