59°21'48"N 153°12'26"W , Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
The level of earthquake activity at Augustine Volcano has declined since yesterday's eruptions but remains elevated above background. The volcano continues to steam vigorously. Field crews reported seeing steam and minor ash emissions from a new vent on the 1986 lava dome and estimated that the top of the plume is 8000 to 10,000 ft (2400 to 3050 m) above sea level. Satellite data show a faint thermal anomaly at the summit. Field crews confirmed mudflows (also visible in the on-island web camera) on the flanks of the volcano. These flows are the likely source of false reports of new lava flows on the volcano.
There is no indication that an eruption similar to that which occurred Tuesday is imminent, but one could occur with little warning.
AVO scientists have been to the volcano today to perform helicopter-based thermal image surveys, collect ash samples, and upgrade instrumentation.
AVO continues to monitor the volcano closely with staff in the office 24 hours a day. AVO will issue further updates as new information and analyses become available.
