Satellite data by KVERT showed the ash column rose up to 9.5-9.8 km a.s.l., and is extending for 192 km to the southwest of the volcano. Probably, the ash plume containing mainly old deposits from collapses in Apakhonchichsky chute.\n\nThe summit explosive-effusive eruption of the volcano continues. Ash explosions up to 12 km (39,400 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

KVERT DAILY REPORT Kamchatkan and Kuriles Volcanic Activity October 30, 2023, all time is UTC SHEVELUCH VOLCANO (CAVW #300270) 56.64 N, 161.32 E; Elevation 3283 m (10768 ft), the dome elevation ~2500 m (8200 ft) Aviation Colour Code is ORANGE An extrusive-effusive eruption of the volcano continues: a lava is extruding into the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, and sometimes an incandescence of the lava dome. In the area of the Karan dome, powerful gas-steam activity is also observed. Satellite data by KVERT showed a thermal anomaly over the volcano. KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 4750 m (15580 ft) Aviation Colour Code is ORANGE An explosive-effusive eruption of the volcano continues. Against the background of explosive activity of the Strombolian type (lava fountaining in the volcanic crater up to 500 m), the lava flow continues to effuse along the Apakhonchichsky chute on the southeastern slope of the volcano. Satellite data by KVERT showed a large bright thermal anomaly over the volcano, and an ash plume stretched in an arc for 965 km to the southeast of the volcano. EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE A moderate activity of the volcano continues. Satellite data by KVERT showed the volcano was obscured by clouds. BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is YELLOW An effusive eruption of the volcano continues; a strong fumarolic activity, hot avalanches and an incandescence of the lava dome is accompanied this process. Satellite data by KVERT showed a thermal anomaly over the volcano. CONTACT INFORMATION: Duty scientist: Olga A. Girina, E-mail: girina(a)kscnet.ru Tel.
