Kamchatkan and Northern Kuriles Volcanic Activity

December 18, 2014, 23:09 UTC (December 19, 2014, 11:09 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 COLOR CODES:

KAMCHATKA
Real-time seismic data (from the Kamchatkan Branch of Geophysical Survey RAS: http:www.emsd.ru):
SHEVELUCH, ZHUPANOVSKY: ORANGE
BEZYMIANNY, KARYMSKY: YELLOW
USHKOVSKY, KLYUCHEVSKOY, PLOSKY TOLBACHIK, KIZIMEN, KORYAKSKY, AVACHINSKY, GORELY, MUTNOVSKY: GREEN

No seismic data:
ICHINSKY, VYSOKY, KOMAROV, GAMCHEN, KHANGAR, KRONOTSKY, KRASHENINNIKOV, TAUNSHITS, KIKHPINYCH, MALY SEMYACHIK, OPALA, KHODUTKA, KSUDACH, ZHELTOVSKY, ILIINSKY, DIKY GREBEN, KOSHELEV, KAMBALNY: GREEN

NORTHERN KURILES
Real-time seismic data (from the Kamchatkan Branch of Geophysical Survey RAS: http:www.emsd.ru), ALAID: GREEN

No seismic data:
EBEKO, CHIKURACHKI, TATARINOV, FUSS PEAK, KARPINSKY: GREEN


SHEVELUCH VOLCANO (CAVW #300270)
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.

A growth of the lava dome continues (a viscous lava flow effuse on the northern its flank), fumarolic activity and incandescence of the dome blocks and hot avalanches accompanies this process. Strong explosion sent ash up to 9-10 km a.s.l. on December 17. Satellite data showed: ash plumes drifted 109 km to the south-east of the volcano on December 14-15 and 35 km to the east-south-east of the volcano on December 17. A thermal anomaly was noting over the lava dome on December 12, 14 and 16-18, the volcano was obscured by clouds during other days of the week.

ZHUPANOVSKY VOLCANO (CAVW #300120)
53.59 N, 159.15 E; Elevation 9702 ft (2958 m)
Aviation Color Code is ORANGE


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. Strong gas-steam activity of the volcano was observing on December 17. Satellite data showed: ash plume drifted about 70 km to the south-east of the volcano on December 15. The volcano was quiet or obscured by clouds during other days of the week.

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


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

A weak seismic activity of the volcano was registering. According to video data, a weak gas-steam activity of the volcano was observing or it was obscured by clouds. Satellite data showed a weak thermal anomaly over the volcano on December 15 and 17-18, the volcano was obscured by clouds during other days of week.

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


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.

There was not seismic data by technical reasons all week. Satellite data showed the volcano was quiet or obscured by clouds last 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.

   or, after a change from higher level: 

Volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
ORANGE

Volcano is exhibiting heightened unrest with increased likelihood of eruption.

   or,

Volcanic eruption is underway with no or minor ash emission.
[specify ash-plume height if possible]
RED

Eruption is forecast to be imminent with significant emission of ash into the atmosphere likely.

  or,

Eruption is underway with significant emission of ash into the atmosphere.
[specify ash-plume height if possible]
