ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Thursday, January 12, 2006 12:05 PM AKST (2105 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. The volcano was partly cloudy in satellite and web camera views. There are no indications that an eruption 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: ORANGE



The Level of Concern Color Code for Augustine Volcano was lowered to ORANGE at 08:25AM AST this morning. After yesterday's eruption, seismic activity declined and has not returned to the levels recorded in the hours prior to the eruption. AVO continues to monitor the volcano closely with staff in the office 24 hours a day.



There have been clear views of the volcano in the island webcam this morning. Today’s field missions include a helicopter trip to conduct FLIR measurements of thermal features of the summit area including fumaroles; equipment maintanence and upgrade at a station along the east coast of the island; and a fixed-wing flight to measure volcanic gases. The helicopter left Homer and is on its way to the island.



AVO will issue further updates as new information and analyses become available.





MARTIN VOLCANO (CAVW#1102-14-)

58.1722°N 155.3611°W, Summit Elevation 6102 ft (1860 m)

Current Level of Concern Color Code: YELLOW



The level of seismic activity at Martin volcano remains above background. Mostly clear night time satellite data show nothing unusual. There are no indications that an eruption is imminent.

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].
