CURRENT STATUS REPORT
Sunday, February 26, 2006 11:50 AM AKST (2050 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 on-island web camera views this weekend, and a low-level plume of steam, volcanic gas, and small amounts of ash has been present. Occasional, but localized ash clouds and light ash fall may be produced by collapses of the lava dome. Evidence of light ash fall on the flanks of the volcano is visible in images from the on-island web camera this week.
Dome building eruptive activity will likely continue over the next few days or weeks and may continue intermittently over the next several months. 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.
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
