ALASKA VOLCANO OBSERVATORY

STATUS REPORT

Wednesday, November 9, 2005 3:05 PM AKST (005 UTC)




SPURR VOLCANO (CAVW#1103-04-)

61.2994°N 152.2511°W, Summit Elevation 11070 ft (3374 m)

Current Level of Concern Color Code: YELLOW



The level of seismic activity at Mount Spurr volcano remains above background. Web camera and satellite images have been obscured by clouds today. There are no indications that an eruption is imminent.



CLEVELAND VOLCANO (CAVW#1101-24-)

52.8232°N 169.9431°W, Summit Elevation 5676 ft (1730 m)

Current Level of Concern Color Code: YELLOW



Clouds obscured Cleveland volcano today in satellite data. No reports of activity have been received from pilots or ground-based observers.



TANAGA VOLCANO (CAVW#1101-08-)

51.885°N 178.1458°W, Summit Elevation 5925 ft (1806 m)

Current Level of Concern Color Code: YELLOW



Seismic activity at Tanaga volcanic cluster remains elevated. Clouds obscured the volcano today in satellite data.



VENIAMINOF VOLCANO (CAVW#1102-07-)

56.1956°N 159.3883°W, Summit Elevation 8225 ft (2507 m)

Current Level of Concern Color Code: YELLOW



No unusual activity was seen in mostly cloudy web camera and satellite images today. Seismic activity remains slightly above background. Low-level steam and ash emissions may occur with no warning and could pose a hazard to people and low-flying aircraft in the vicinity of the intracaldera cone.

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].
