Current Level of Concern Color Code: RED
Two explosive eruptions of Augustine Volcano have occurred since the last information release, the first at 18:58 (AST) yesterday evening and the second at 00:14 (AST) this morning. These events were similar in size and duration to the previous four. In response to these eruptions, the National Weather Service had issued an ash fall advisory for the western Kenai Peninsula south of Ninilchik, which has since expired. Seismicity is relatively quiet at this time, but AVO expects renewed eruptive activity today.
Based on historical records from the eruptions in 1976 and 1986, as well as all available data from this eruption, we expect the current sequence of explosions will likely continue for several days to perhaps two to three weeks. The principal hazard associated with these explosions is airborne ash that can be transported downwind for hundreds of miles. Dangerous pyroclastic flows and mudflows are expected to occur on all flanks of the volcano.
AVO will continue monitoring Augustine on a 24-hour, 7-day per week basis
