VONA/KVERT WEEKLY INFORMATION RELEASE 49-2013
Kamchatkan and Northern Kuriles Volcanic Activity

December 05, 2013, 22:29 UTC (December 06, 2013, 10:29 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.

SHEVELUCH VOLCANO (CAVW #1000-27-)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Color Code is ORANGE


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

Eruption of the volcano continues: a new lava dome continues to extrude on the north-western part of the old lava dome, moderate ash explosions up to 13,100-16,400 ft (4-5 km) a.s.l., fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome.

KARYMSKY VOLCANO (CAVW #1000-13-)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE


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

Moderate seismic activity of the volcano continues. Strombolian and Vulcanian activity of the volcano was observed on December 02-03. Satellite data showed a bright thermal anomaly over the volcano all week.

Aviation Color Code is YELLOW


Eruption of the volcano continues. Ash explosions up to 32,800 ft (10.0 km) a.s.l. could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Moderate seismic activity of the volcano continues. Video data showed strong and moderate gas-steam activity of the volcano. Satellite data showed a very weak thermal anomaly over the volcano summit all week.

55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW


Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

Seismicity of the volcano was weak. Video data showed a moderate gas-steam activity of the volcano. Satellite data showed a weak thermal anomaly over the volcano all week.

PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-)
55.83 N, 160.39 E; Elevation 10119 ft (3085 m)
Aviation Color Code is YELLOW


Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

A weak seismic activity of the volcano continues. A thermal anomaly was observed on satellite images at the northern area of Tolbachinsky Dol all week.

KIZIMEN VOLCANO (CAVW #1000-23-)
55.13 N, 160.32 E; Elevation 8151 ft (2485 m)
Aviation Color Code is YELLOW


Extrusive eruption of the volcano gradually finishing. Activity of the volcano could affect low-flying aircraft.

A weak seismic activity of the volcano continues. Video data showed moderate gas-steam activity of the volcano. Satellite data showed a very weak thermal anomaly over the volcano all week.

In Russia, KVERT, on behalf of the Institute of Volcanology and Seismology (IVS) FED 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 analyses daily satellite imagery (since 2002 till now); information from remote scientific observation stations; real-time seismic data for 11 Kamchatkan volcanoes (data 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.
