Okmok Volcano: 53.4oN, 168.17oW; 760 m (2,500 ft)
Eruptive activity at Okmok Volcano is continuing. Indications of hot lava
flows within the caldera and small, low level, ash plumes have been
observed via satellite during the last week. The current eruptive
phase began February 13. 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 not
monitored seismically and is not assigned a color code.
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).
