Current Level of Concern Color Code: RED
Another explosive event occurred at Augustine Volcano this morning at approximately 8:47 AM AST (17:47 UTC). Pilot reports and satellite imagery confirm an ash cloud with lightning in excess of 30,000 ft above sea level that is moving eastward. Seismic data suggest that pyroclastic flows and lahars (volcanic mudflows) are occurring on the flanks of the island and possibly extending beyond.
Similar short-lived explosive activity is expected to continue over the next several days or weeks. Individual explosions are expected to produce ash plumes accompanied by pyroclastic flows and lahars (volcanic mudflows) on the flanks of the volcano. The National Weather Service (NWS) and AVO are tracking the drifting ash clouds. Aviation users please refer to the latest SIGMETS for forecasts of ash movement. Ashfall Advisories will be issued by the NWS, in collaboration with AVO for possible ash fall out.
AVO is monitoring the situation closely and will issue further updates as new information and analyses become available.
