CURRENT STATUS REPORT
Wednesday, February 22, 2006 1:25 PM AKST (2225 UTC)
59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
Unrest continues at Augustine Volcano. Seismicity has been relatively low but remains above background levels. Rockfalls and avalanches from the lava dome continue to be recorded by AVO seismic stations but appear to be declining. Satellite images of the volcano show that a thermal anomaly in the summit area persists. Images from a low-light camera in Homer show the summit of Augustine to be glowing last night.
A plume composed of variable amounts of gas, steam, and small amounts of ash is likely being emitted intermittently from Augustine's summit. Occasional, very localized ash clouds and light ash fall will be produced by collapses from the lava dome. Evidence of light ash fall on the flanks of the volcano are visible in web camera images from yesterday and this morning.
During dome building eruptions, brief, energetic explosions can occur with little or no warning. Such explosions could produce larger amounts of ash leading to the formation of drifting ash clouds that could rise more than 25,000 feet above sea level.
Dome building eruptive activity will likely continue over the next few days or weeks and may continue intermittently over the next several months.
AVO is monitoring the situation 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
