CURRENT STATUS REPORT
Friday, April 14, 2006 12:40 PM AKDT (2040 UTC)
59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
Seismicity over the past 24 hours at Augustine has remained low, but still slightly above background. The on-island webcam shows minor steaming from the summit and clear satellite views did not detect a thermal anomaly.
The present level of seismicity, although low, indicates that eruptive activity continues but at a low level. It is possible for occasional rock avalanches, and rock falls originating from the summit lava dome or the snouts of the lava flows on the north and northeast flanks to occur. Small, dilute ash clouds resulting from these processes may be generated, but are unlikely to extend beyond Augustine Island.
Lava extrusion and dome-building eruptive activity continues but at a low level. It is still possible for brief, energetic explosions to 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.
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 are 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.
