CURRENT STATUS REPORT
Tuesday, February 28, 2006 12:20 PM AKST (2120 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. Over the past 24 hours, seismicity has been relatively low but remains above background levels. Seismic data indicate that small rock avalanches from the lava dome are occurring intermittently. The summit has been visible in clear web camera views this morning, and a low-level plume of steam has been present. Occasional, but localized ash clouds and light ash fall may be produced by some of the more energetic collapses of the lava dome.
Dome building eruptive activity will likely continue over the next few weeks or months. During this time, 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.
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
