Video and satellite data by KVERT show: the ash plume from hot avalanches which collapsing from the the eastern part of the lava dome is extending for 210 km to the east-south-east of the volcano.\n\nThe extrusive eruption of the volcano continues. 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.
