 (7) Notice Number:2025-17
 (8) Volcano Location:N 55 deg 58 min E 160 deg 35 min
 (9) Area:Kamchatka, Russia
(10) Summit Elevation:2882 m (9452.96 ft)
(11) Volcanic Activity Summary:An extrusive-effusive eruption of the volcano increased significantly on 11 April: hot avalanches collapsed on the eastern slopes of the lava dome, and the ash from which rose up to 3-4 km a.s.l. Satellite data by KVERT showed an ash plume extending about 90 km to the north-east of the volcano.

An effusive activity of the Bezymianny volcano is gradually increasing, probably the volcano is preparing for a strong explosive eruption. Ash explosions up to 10-15 km (32,800-49,200 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
