Against the background of explosive activity of the Strombolian type (lava fountaining in the volcanic crater), the lava flows continue to effuse along the Apakhonchichsky and Kozyrevsky chutes on the southern slopes of the volcano. Lava flows in the Apakhonchichsky chute melt buried snowfields and glaciers. Powerful phreatic explosions are observed in the Apakhonchichsky chute, and collapses of old pyroclastic material from its sides. Satellite data by KVERT showed ash plume, containing mainly old ash from pyroclastic collapses from the sides of the Apakhonchich chute, is extending for 83 km to the northeast of the volcano.\n\nThe summit explosive-effusive eruption of the volcano continues. Ash explosions up to 7-8 km (23,000-26,240 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 22, 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 the volcano was obscured by clouds. 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), the lava flows continue to effuse along the Kozyrevsky and Apakhonchichsky chutes on the southern slopes of the volcano. Lava flows in the Apakhonchichsky chute melt buried snowfields and glaciers, and as result of phreatic explosions, old pyroclastic material collapse from Apakhonchichsky chute sides. Satellite data by KVERT showed a large bright thermal anomaly over the volcano; ash plume, containing mainly old ash from pyroclastic collapses from the Apakhonchich chute sides, extended for 95 km to the northeast 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 explosive activity of the volcano continues. According to visual data from Severo-Kurilsk, explosions sent ash up to 2 km a.s.l., and ash clouds drifted to the northeast of the volcano. 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 extrusive-effusive eruption of the volcano continues; a strong fumarolic activity, numerous hot avalanches and an incandescence of the lava dome is accompanied this process.

A danger of ash explosions up to 10 km (32,800 ft) a.s.l. remains. Ongoing activity could affect international and low-flying aircraft. The extrusive-effusive eruption of the volcano continues: a lava is extruded out in the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, and sometimes an incandescence of the lava dome. A powerful gas-steam activity is also observed at the area of the Karan dome. Satellite data by KVERT showed a thermal anomaly over the volcano all week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Sheveluch KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 4750 m (15580 ft) Aviation Colour Code is ORANGE The summit explosive-effusive eruption of the volcano continues. Ash explosions up to 7-8 km (23,000-26,200 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. The summit explosive-effusive eruption of the volcano continues. Against the background of explosive activity of the Strombolian type (lava fountaining in the volcanic crater), the lava flows continue to effuse along the Apakhonchichsky and Kozyrevsky (from 17 October) chutes on the southern slopes of the volcano. Satellite data by KVERT showed a large thermal anomaly over the volcano all week: ash plumes, containing mainly old ash from pyroclastic collapses from the sides of the Apakhonchich chute, were raising up to 6 km a.s.l., and extended for 430 km to the eastern directions of the volcano. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Klyuchevskoy EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE A moderate explosive eruption of the volcano continues. Ash explosions up to 6 km (19,700 ft) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk. The moderate explosive eruption of the volcano continues. According to visual data from Severo-Kurilsk, explosions sent ash up to 4 km a.s.l. on 14 and 19 October; ash clouds moved to the eastern directions of the volcano. Satellite data by KVERT showed a thermal anomaly over the volcano on 14 October; the volcano was quiet or obscured by clouds during other days of the week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Ebeko BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is YELLOW An extrusive-effusive eruption of the volcano continues. Ongoing activity could affect low-flying aircraft. An extrusive-effusive eruption of the volcano continues. Satellite data by KVERT showed: at 04:30 UTC on 18 October, 2023, a paroxysmal explosive eruption of the volcano occurred with ash removal up to 11 km a.s.l. The ash cloud moved for about 850 km, first to the northeast, then to the northwest of the volcano. A small ashfall was noted in the Kozyrevsk. The thermal anomaly over the volcano was observed during the week. On 19 October, an ash plume extended to the northeast of the volcano. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Bezymianny IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A.

KVERT scientists are available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week and by phone during the evenings since 2005. KVERT produces daily satellite monitoring (since 2002 till now) of Kamchatkan and Kuriles Volcanoes to using the information system (IS) “Remote monitoring of the activity of Kamchatka and Kuriles volcanoes (VolSatView)”, which was created in 2011-2014 the joint efforts of the scientists of KVERT IVS FEB RAS, the Space Research Institute RAS, the Computing Center FEB RAS and the Far Eastern Scientific Center Planet. IS continues to evolve. KVERT analyses information from remote scientific observation stations and seismic data for volcanoes: Alaid, Avachinsky, Bezymianny, Gorely, Karymsky, Kizimen, Klyuchevskoy, Koryaksky, Mutnovsky, Plosky Tolbachik, Sheveluch, Ushkovsky, Zhupanovsky (from the Kamchatkan Branch of Geophysical Survey RAS); and other information to monitor activity at Kamchatkan and Kuriles Volcanoes.
