KVERT WEEKLY INFORMATION RELEASE 16-2022
Kamchatkan and Kuriles Volcanic Activity
April 21, 2022, 23:33 UTC (April 22, 2022, 11:33 KST)

KVERT monitor active volcanoes of Kamchatka and the Kurile Islands. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

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

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.

A growth of the lava dome continues, a strong fumarole activity, and an incandescence of the lava dome, explosions, and hot avalanches accompanies this process. Satellite data by KVERT showed: on 15-16 April, explosions sent ash up to 5 km a.s.l., the ash clouds moved for 75 km to the southeast of the volcano; a thermal anomaly over the volcano all week.

KARYMSKY VOLCANO (CAVW #300130)
54.05 N, 159.44 E; Elevation 1486 m (4874 ft)
Aviation Colour Code is ORANGE

A moderate explosive activity 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.

The eruptive activity of the volcano continues. Satellite data by KVERT showed: a powerful explosive event began at 20:05 UTC on 19 April, the ash column rose up to 11 km a.s.l., ash clouds continue to be observed on 21 April at a distance of more than 2000 km to the northeast of the volcano. Ashfalls were noted on the territory of the Kronotsky Reserve (cordons Semyachinsky, Valley of Geysers), and at Cape Nalychevo. In addition, on 17–19 and 21 April, explosions sent ash up to 7.5 km a.s.l., ash plumes and clouds moved for 500 km to the northeast, southwest, southeast, and east of the volcano. A thermal anomaly over the volcano was noted all week.

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. Aerosol clouds and ash plumes from hot avalanches could occur at any time. Ongoing activity could affect low-flying aircraft.

The extrusive-effusive eruption of the volcano continues, a strong fumarole activity, and an incandescence of the lava dome, and hot avalanches accompanies this process. Satellite data by KVERT showed a thermal anomaly over the volcano all week.

In Russia, KVERT, on behalf of the Institute of Volcanology and Seismology (IVS) FEB RAS, is responsible for providing information on volcanic activity to international air navigation services for the airspace users.

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.
