ALASKA VOLCANO OBSERVATORY

CURRENT STATUS REPORT

Sunday, April 9, 2006 12:00 PM AKDT (2000 UTC)




AUGUSTINE VOLCANO (CAVW#1103-01-)

59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)

Current Level of Concern Color Code: ORANGE



Seismicity over the last 24 hours at Augustine has increased somewhat, probably reflecting an increased number of rockfalls. The on-island webcam shows cloudy conditions. Satellite views continue to show a thermal anomaly.



Low-level eruptive activity continues at Augustine Volcano. Occasional hot block-and-ash flows, rock avalanches, and rock falls originating from the summit lava dome and the steep snouts of the lava flows on the north and northeast flanks continue to be recorded by the seismic network. Small, dilute ash clouds resulting from these processes may be generated, but are likely to be confined to the immediate vicinity of the volcano. During periods of high wind at the volcano, minor amounts of ash may be swept from the flanks and carried downwind.



Lava extrusion and dome-building eruptive activity is likely to continue intermittently over the next several weeks to months. Brief, energetic explosions of ash can occur with little or no warning. Such explosions could produce significant amounts of ash and drifting ash clouds that could rise more than 25,000 feet above sea level.



AVO is monitoring Augustine closely and the observatory remains staffed 24/7. For up-to-date Ashfall Advisories and wind trajectories, please refer to the National Weather Service website: http://pafc.arh.noaa.gov/augustine.php



VENIAMINOF VOLCANO (CAVW#1102-07-)

56°11'44"N 159°23'18"W , Summit Elevation 8225 ft (2507 m)

Current Level of Concern Color Code: YELLOW



Seismicity remains low. Webcam views are cloudy today. Satellite views show nothing unusual.



Production of short-lived, very small-volume steam and ash bursts from the intracaldera cone has been typical of this volcano intermittently over the past few years. There are no indications that a larger eruption is imminent. Ash clouds and fallout from these events are not likely to extend beyond the caldera rim, but could pose a hazard to people and low-flying aircraft in the vicinity of the active cone.

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].
