ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Friday, December 16, 2005 3:35 PM AKST (035 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. Clouds obscured views of the volcano in web camera and satellite images today. There are no indications that an eruption is imminent.







VENIAMINOF VOLCANO (CAVW#1102-07-)

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

Current Level of Concern Color Code: YELLOW



Seismicity at Veniaminof volcano remains low. Clouds obscured views of the volcano by satellite and web camera today. Given the recent pattern of activity at the volcano, steam and ash emissions may occur without warning and could pose a hazard to people and low-flying aircraft in the vicinity of the active cone. However, there are no indications of activity at the volcano in the past 24 hours. There are no indications that eruptive activity is imminent.







AUGUSTINE VOLCANO (CAVW#1103-01-)

59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)

Current Level of Concern Color Code: YELLOW



Elevated seismicity continues. Web camera and satellite images of the volcano were obscured by clouds today. There is no indication that a large eruption of Augustine is imminent. AVO has fieldwork planned on the island during the first good-weather window to deploy additional equipment, and to make detailed observations of any recent morphological changes.



Small explosions are likely to continue to occur. These explosions occur with no warning and could affect low-flying aircraft in the vicinity of the volcano. Augustine remains in color code Yellow and AVO continues to monitor the situation closely.

The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.
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].
