KVERT WEEKLY INFORMATION RELEASE 25-2019
Kamchatkan and Kuriles Volcanic Activity

June 21, 2019, 00:06 UTC (June 21, 2019, 12:06 KST)

KVERT monitor 30 active volcanoes of Kamchatka and 6 active volcanoes of Northern Kuriles. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

SUMMARY OF AVIATION COLOUR CODES:

KAMCHATKA

SHEVELUCH VOLCANO (CAVW #300270)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Colour Code is ORANGE


Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800-49,200 ft (10-15 km) 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 dome blocks and hot avalanches accompanies this process. Satellite data showed the thermal anomaly over the volcano all week.

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


The explosive eruption of the volcano continues. Ash explosions up to 19,700-23,000 ft (6-7 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

A moderate activity of the volcano continues. According to satellite data, a weak thermal anomaly was registering over the volcano on 14 June, the volcano was obscured by clouds in the other days of week.

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


A moderate activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircrafts.

A moderate activity of the volcano continues. Satellite data shows a weak thermal anomaly over the volcano on 14-15 June, the volcano was obscured by clouds in the other days of week.

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


A moderate eruptive activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk.

A moderate activity of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 2.5 km a.s.l. on 14-15 June, ash plumes extended to the northwest and northeast of the volcano. Satellite data shows the volcano was quiet or obscured by clouds all week.

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


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

A growth of the lava dome continues, a strong fumarolic activity and an incandescence of the dome accompanies this prosess. Satellite data shows the thermal anomaly over the volcano on 14-15 and 19 June, the volcano was obscured by clouds in the other days of 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 was 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); 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 Northern 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]
