The volcano continues to emit ash. The level of seismicity remains high. At 11:18 AST (20:18 UTC) a considerably stronger explosion occurred and lasted approximately 4 minutes. The NWS reports the height of the ash cloud at 25,000 ft at 11:21 AST (20:21 UTC) based on radar data.
Thanks!
ALASKA VOLCANO OBSERVATORY INFORMATION RELEASE Sunday, January 29, 2006 8:40 AM AKST (1740 UTC) AUGUSTINE VOLCANO (CAVW#1103-01-) 59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m) Current Level of Concern Color Code: REDSince 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.
