Sunday, January 29, 2006 6:30 PM AKST (330 UTC)
59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: RED
Augustine volcano has been in a state of continuous eruption for about the past 24 hours. The eruption has been characterized by steady ash emission and small pyroclastic flows. The present eruption began Saturday afternoon at 14:30 AKST and since 20:19 AKST January 28 (0519 January 29 UTC) the level of seismicity has been generally elevated.
An observation flight to the volcano this afternoon encountered diffuse drifting ash clouds from the summit to about 25,000 feet. The ash clouds and overcast conditions hindered attempts to make close-in observations. Ash and steam clouds were observed rising from pyroclastic flows on the north flank of the volcano. Steam plumes were observed rising from the NNE coastline indicating that some of the the pyroclastic flows had entered the sea.
Ash emission from the volcano has been obvious in satellite and radar observations. The plume is ash-rich and is drifting to the west-southwest and then south (over Kodiak Island) at up to 25,000 to 30,000 feet above sea level. For current ash fall advisories and wind trajectories, please see the National Weather Service website: http://pafc.arh.noaa.gov/augustine.php.
At this time it is uncertain how long this phase of the eruption will last, but the present type of activity may continue for hours to days.
