AUGUSTINE VOLCANO (CAVW#1103-01-)

59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)

Current Level of Concern Color Code: RED

 

AVO recorded two discrete explosions at the summit of Augustine Volcano this morning at 4:44 a.m. and 5:13 a.m. (AST) and responded by changing the level of concern color code from ORANGE to RED. Satellite data confirm that an ash cloud was produced and in collaboration with the National Weather Service (NWS), the height of the cloud was estimated at 30,000 feet above sea level. NWS and AVO are tracking the ash plume which has detached from the vent and is presently drifting to the north and east of Augustine. As of 7:40 a.m. (AST), the ash cloud had traveled 25 mi (40 km) east and 30 mi (50 km) north. An ash-fall advisory was issued by the NWS at 6:44 a.m. (AST).
