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), strong 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, with the exception of 20-21 March, when the volcano was obscured by clouds. An ash plume was extending for about 38 km to the north from the volcano on 23 March.
