KVERT/Volcano Observatory Notification to Aviation

VONA/KVERT WEEKLY INFORMATION RELEASE 16-2014
Kamchatkan and Northern Kuriles Volcanic Activity

April 17, 2014, 07:32 UTC (April 17, 2014, 19:32 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, KARYMSKY: ORANGE
BEZYMIANNY: 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, ZHUPANOVSKY, OPALA, KHODUTKA, KSUDACH, ZHELTOVSKY, ILIINSKY, DIKY GREBEN, KOSHELEV, KAMBALNY: GREEN

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


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.

A growth of the lava dome active continues (a viscous lava flow effuse on southeastern flank), moderate ash explosions, fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a bright thermal anomaly over the lava dome all week. Ash plumes rose up to 13,100 ft (4 km) a.s.l. and extended to the south-east of the volcano on April 16-17.

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.

A moderate seismic activity of the volcano was registering. Strombolian and moderate Vulcanian activity of the volcano continues. Satellite data showed a thermal anomaly over the volcano all time, except on April 11-14, when the volcano was obscured by clouds.

BEZYMIANNY VOLCANO (CAVW #1000-25-)
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.

A seismic activity of the volcano was very low or it was not registering last week. Video data showed a moderate gas-steam activity of the volcano. Satellite data showed a weak thermal anomaly over the volcano or it was obscured by clouds.

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.
