CURRENT STATUS REPORT
Friday, April 21, 2006 11:25 AM AKDT (1925 UTC)
59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
Rockfalls and avalanche events continue. Web camera images are temporarily unavailable.
Seismicity, rates of rockfall signals, and visual observations from overflights earlier this week indicate lava effusion is continuing. Small, dilute ash clouds produced by occasional rockfalls and avalanches may still occur, but are unlikely to extend beyond Augustine Island. Brief energetic explosions of ash are still possible.
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. Web camera images are temporarily unavailable.
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.
