KVERT WEEKLY INFORMATION RELEASE 49-2021
Kamchatkan and Kuriles Volcanic Activity

December 02, 2021, 23:52 UTC (December 03, 2021, 11:52 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 accompanies this process. Satellite data by KVERT showed 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 eruptive 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.

The eruptive activity of the volcano continues. Satellite data by KVERT showed: on 25 November, and 02 December, explosions sent ash up to 6 and 4 km a.s.l., ash clouds moved for 30 km to the north-west, and 100 km to the east-northeast of the volcano, respectively; a thermal anomaly was noted over the volcano on 27-29 November, and 02 December; the volcano was quiet or 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 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 by KVERT showed a thermal anomaly over the volcano on 26-30 November, the volcano was obscured by clouds in the other days of week.

EBEKO VOLCANO (CAVW #290380)
50.69 N, 156.01 E; Elevation 1156 m (3792 ft)
Aviation Colour Code is YELLOW


A moderate gas-steam activity of the volcano continues. A danger of ash emission up to 6 km (19,700 ft) a.s.l. at any time is remains. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk.

A moderate gas-steam 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.

Авиационные цветовые коды

ЗЕЛЕНЫЙ

Вулкан находится в нормальном – неэруптивном состоянии.

или, после того, как перешел от более высокого уровня активности:

Вулканическая активность считается прекратившейся, или вулкан вернулся к нормальному – неэруптивному состоянию.

ЖЕЛТЫЙ

Вулкан проявляет признаки повышения активности выше известного уровня фона.

или, после того, как перешел от более высокого уровня активности:

Вулканическая активность значительно снизилась, но тщательный мониторинг продолжается, потому что возможно возобновление ее роста.

ОРАНЖЕВЫЙ

Вулкан проявляет повышенную активность с высокой вероятностью извержения.

или,

Извержение вулкана идет с отсутствием или незначительным выбросом пепла.
[указать высоту пеплового шлейфа, если это возможно]

КРАСНЫЙ

Извержение, по прогнозам неизбежно со значительным выбросом пепла в атмосферу.

или,

Извержение идет со значительным выбросом пепла в атмосферу.
[указать высоту пеплового шлейфа, если это возможно]
