Ash explosions up to 6 km (19,700 ft) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft. The moderate explosive eruption of the volcano continues. According to the data by Tokyo VAAC and KVERT, the explosive eruption of Chicurachki volcano began on 28 January, 2023. Satellite data by KVERT showed the explosions sent ash up to 4 km a.s.l., and ash plumes extended for 125 km to the southeast, east and northeast of the volcano on 28-29 and 31 January, and 01-02 February; a thermal anomaly over the volcano on 31 January. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Chikurachki BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is YELLOW The extrusive-effusive eruption of the volcano continues. Ongoing activity could affect low-flying aircraft. The extrusive-effusive eruption of the volcano continues. The eruption is accompanied by gas-steam activity of the volcano and sometimes by the collapses of hot avalanches along the lava dome slopes.

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.
