CURRENT STATUS REPORT
Saturday, April 8, 2006 12:25 PM AKDT (2025 UTC)
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 remained quiet compared to recent weeks, but is still above background. The on-island webcam shows cloudy conditions. Partly cloudy 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
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 and satellite views were cloudy today.
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.
