59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: RED
Since last night the volcano has been in a state of continuous eruption, accompanied by ash emission. The present eruption began yesterday afternoon at 14:30. Since 20:19 AKST January 28 (0519 January 29 UTC) the level of seismicity has been generally elevated, with large seismic signals occurring at intervals. Satellite imagery from this morning indicates a widespread thermal anomaly to the north of the summit that is likely the result of pyroclastic-flow deposits.
Ash emission from the volcano has been continuous and satellite and radar observations indicate an ash-rich plume drifting approximately west-southwest and then south (over Kodiak Island) at up to 14,000 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.
