Kamchatka and the Northern Kuriles volcanoes: Erupting or Restless

KVERT/Volcano Observatory Notification to Aviation

VONA/KVERT WEEKLY INFORMATION RELEASE 21-2015
Kamchatkan and Northern Kuriles Volcanic Activity

May 21, 2015, 21:25 UTC (May 22, 2015, 09:25 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
KLYUCHEVSKOY, BEZYMIANNY, ZHUPANOVSKY: YELLOW
USHKOVSKY, 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 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 accompanies this process. Satellite data showed a thermal anomaly over the lava dome on May 15-19.

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


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.

Moderate eruptive activity of the volcano probably continues. Satellite data showed an ash plume up to 27 km to the west from the volcano on May 16, and a thermal anomaly on May 15-16.

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


Gas-steam activity of the volcano continues. Aerosol plumes and sometimes aerosol-ash plumes could affect low-flying aircraft.

Moderate gas-steam activity of the volcano continues. Satellite data showed a thermal anomaly over the volcano on May 16-19.

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.

Weak activity of the volcano continues. According to video data, a gas-steam activity of the volcano was observed. Satellite data showed a weak thermal anomaly over the volcano on May 15-19.

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


Activity of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Activity of the volcano continues. Satellite data showed a weak thermal anomaly over the volcano on May 14; an ash cloud drifted up to 470 km to the east from the volcano on May 20.

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.
