59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: RED
No explosive events associated with ash plumes have occurred since the last information release (8:40 a.m. AST). Seismicity remains above background levels and explosive activity could occur at any time.
Earlier today, AVO received reports from pilots of sulfur smell and diffuse brown haze at flight altitudes in Southeast Alaska (near Yakatat and Sitka). These diffuse ash and gas clouds are presumably from yesterday's explosive events. Aviation users please refer to the current SIGMETS for additional guidance.
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. During an eruption, dangerous pyroclastic flows and mudflows are expected to occur on the flanks of the volcano.
AVO will continue monitoring Augustine on a 24-hour, 7-day per week basis.
