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 a flight yesterday afternoon indicated that the summit was steaming vigorously, consistent with the formation of a new lava dome. Observers on the flight also noted ballistic bombs, block and ash flow deposits, and dilute-cloud surge deposits on the volcano's flanks. A white ash-poor steam plume was observed rising to about 8500 ft (2600 m). Weather permitting, a gas measurement and observation flight is planned for today.
