Okmok Volcano: 53.4°N, 168.17° W; 760 m (2,500 ft)
Eruptive activity at Okmok, which began February 13, is continuing.
Lava flows within the caldera are indicated by satellite images.
Thin, low level, ash plumes have also been observed drifting
downwind from the volcano. Okmok Volcano is not monitored
seismically and is not assigned a color code. Based on past
eruptive history, lava flows and ash emission may continue to
occur without additional warning for a period of weeks to months.
Okmok is on the eastern end of Umnak Island, 75 miles southwest
of Dutch Harbor. The nearest settlements are Nikolski (45 miles
W) and former Fort Glenn military base (10 miles E).
