 (7) Notice Number:2022-166
 (8) Volcano Location:N 56 deg 38 min E 161 deg 18 min
 (9) Area:Kamchatka, Russia
(10) Summit Elevation:3283 m (10768.24 ft), the dome elevation ~2500 m (8200 ft)
(11) Volcanic Activity Summary:A growth of the lava dome continues, a strong fumarole activity, an incandescence of the lava dome, explosions, and hot avalanches accompanies this process. Video and satellite data by KVERT show: the ash plume from hot avalanches which collapsing from the the different flanks of the lava dome is extending for 130 km to the eastnortheast of the volcano.

The 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.
