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 flow reveal 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 gas-steam activity were observing all week. Satellite data by KVERT showed an intensive thermal anomaly over the lava dome all week.
Activity on the volcano seems to be increasing again. Constant glow and incandescent rockfalls at the active lava dome are visible on webcam imagery.
Based on satellite data, an eruption (explosion or pyroclastic flow) was reported this morning to have produced an ash plume that rose to 24,000 ft (7.3 km) altitude and drifted west.
