59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
Earthquake activity at Augustine Volcano remains at low levels but is still well above background. Based on the characteristics of previous eruptions, it is likely, but not certain, that more explosive eruptions will occur. These events are likely to be similar to those of January 13, 14, and 17 and it is possible for them to occur with little or no warning. AVO is monitoring the situation closely and the observatory is staffed 24/7.
Observations made on an aerial over flight this afternoon indicated that the summit continues to steam vigorously, consistent with the formation of a new lava dome, although the amount of steam obscured conclusive views of the summit and it is still uncertain if a dome has formed at the summit. A white ash-poor steam plume was observed rising to just above the summit and drifting to the east. AVO scientists were able to measure volcanic gases in the plume, but results are not yet available.
