Kanaga Volcano has intermittently vented low levels of steam and ash. Observers in Adak reported ash-rich plumes reaching several thousand feet above the 4287-foot summit of the volcano on Friday, February 18, 1994. Satellite images confirmed the presence of ash in the plume emitted from the cone. Continued minor, low-level steam and ash venting was reported by airline crews and ground observers on Monday, 21 February. Kanaga has not been seen during the past 4 days due to poor weather conditions.
