Sheveluch, Kamchatka : ash plume rose up to 5.5 km.

Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

A growth of the lava dome continues (a viscous lava block extrude in the northern its part), fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany this process. According to video data, an incandescence of the dome lava blocks and moderate hot avalanches were observing all week. The hot avalanche collapsed from western flank of the lava dome on 31 December, an ash plume rose up to 5.5 km a.s.l. and extended about 50 km to the south-east of the volcano. Satellite data by KVERT showed an intensive thermal anomaly over the lava dome all week.
