KVERT WEEKLY INFORMATION RELEASE 03-2021
Kamchatkan and Kuriles Volcanic Activity
January 15, 2021, 00:56 UTC (January 15, 2021, 12:56 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 fumarolic activity, and an incandescence of the lava dome and hot avalanches accompanie this process. Satellite data showed a thermal anomaly over the lava dome all week.

KLYUCHEVSKOY VOLCANO (CAVW #300260)
56.06 N, 160.64 E; Elevation 4750 m (15580 ft)
Aviation Colour Code is ORANGE

A moderate 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.

A moderate explosive-effusive eruption of the volcano continues, the Strombolian, gas-steam and sometimes Vulcanian activity is observing. The lava flow continues to move along Kozyrevsky chute on the southern volcanic flank. Satellite data showed a large bright thermal anomaly in the area of the volcano all week; all week gas-steam plumes containing some amount of ash rose up to 6 km a.s.l., and extended for 90 km to the different directions of the volcano.

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. The ash explosions up to 5-7 km (16,400-23,000 ft) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

A moderate activity of the volcano continues. Satellite data 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 eruptive activity 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 4.5 km a.s.l. on 07-10, and 13-14 January; ash clouds drifted to the eastern directions of the volcano. Satellite data showed the volcano was quiet or obscured by clouds.

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

A moderate gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data showed a thermal anomaly over the lava dome all week.

SARYCHEV PEAK VOLCANO (CAVW #290240)
48.09 N, 153.2 E; Elevation 1496 m (4907 ft)
Aviation Colour Code is YELLOW

A moderate gas-steam activity 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 moderate activity of the volcano continues. Satellite data showed a thermal anomaly over the volcano on 07-10, and 12-13 January; a gas-steam plume extended for 40 km to the northeast of the volcano on 12 January.

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.
