KVERT WEEKLY INFORMATION RELEASE 05-2025
Kamchatkan and Kuriles Volcanic Activity
January 30, 2025, 23:16 UTC (January 31, 2025, 11:16 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-effusive eruption of the Sheveluch volcano continues. The 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 Young Sheveluch volcano and the extrusive eruption of the 300 years RAS lava dome continue. The growth of the lava domes is accompanied by powerful gas-steam activity. Satellite data by KVERT showed thermal anomalies over the both domes all week; a plume of resuspended ash was extending for 90 km to the southeast of the volcano on 25 January.

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

A moderate activity of the volcano continues. Ash explosions up to 10 km (32,800 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

A moderate activity of the volcano continues. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 24-27 January, the volcano was obscured by clouds in the other days of the week.

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

A moderate activity of the volcano continues. Increased effusive activity of the volcano is possible. Ongoing activity could affect low-flying aircraft.

A moderate activity of the volcano continues, it is accompanied by powerful gas-steam emissions. 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 YELLOW

A moderate activity of the volcano continues. The danger of ash explosions up to 6 km (19,700 ft) a.s.l. remains. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk.

A moderate activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds 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.
