KVERT WEEKLY INFORMATION RELEASE 14-2023
Kamchatkan and Kuriles Volcanic Activity
March 30, 2023, 20:45 UTC (March 31, 2023, 08:45 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

An 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, an incandescence of the lava dome, sometimes explosions, and hot avalanches accompanies this process. Satellite data by KVERT showed ash plumes extended up to 80 km to the east from the volcano on March 25, 26, and 28-30, and a thermal anomaly over the volcano all week.

BEZYMIANNY VOLCANO (CAVW #300250)
55.97 N, 160.6 E; Elevation 2882 m (9453 ft)
Aviation Colour Code is ORANGE

An extrusive-effusive eruption of the volcano continues. Ongoing activity could affect low-flying aircraft.

An extrusive-effusive eruption of the volcano continues. An eruption accompanies by gas-steam activity of the volcano and sometimes by the collapses of hot avalanches along the lava dome slopes. An explosive eruption with ash column up to 6 km a.s.l. and ash plume extended about 25 km to the east from the volcano occurred on March 29. Satellite data by KVERT showed a thermal anomaly over the volcano all week.

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.

A moderate explosive eruption of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 2.8 km a.s.l. on March 23, 26, and 29-30; ash clouds moved to the north-east from the volcano. Satellite data by KVERT showed a thermal anomaly over the volcano on March 29-30, the volcano was quiet or obscured by clouds during other days of the 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.
