KVERT congratulate all with Great Victory!

VONA/KVERT WEEKLY INFORMATION RELEASE 18-2017
Kamchatkan and Northern Kuriles Volcanic Activity
May 05, 2017, 03:59 UTC (May 05, 2017, 15:59 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
BEZYMIANNY, KLYUCHEVSKOY, SHEVELUCH: ORANGE
KAMBALNY: YELLOW
AVACHINSKY, DIKY GREBEN, GAMCHEN, GORELY, ICHINSKY, ILIINSKY, KARYMSKY, KHANGAR, KHODUTKA, KIKHPINYCH, KIZIMEN, KOMAROV, KORYAKSKY, KOSHELEV, KRASHENINNIKOV, KRONOTSKY, KSUDACH, MALY SEMYACHIK, MUTNOVSKY, OPALA, PLOSKY TOLBACHIK, TAUNSHITS, USHKOVSKY, VYSOKY, ZHELTOVSKY, ZHUPANOVSKY: GREEN

NORTHERN KURILES
EBEKO: ORANGE
ALAID, CHIKURACHKI, FUSS PEAK, KARPINSKY, TATARINOV: 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 26,200-32,800 ft (8-10 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 reveal in the northern its part), strong fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany this process. Satellite data by KVERT showed: explosions sent ash up to 9 km a.s.l. on 30 April; ash clouds and plumes drifted for about 730 km to the south-west, north-west and south-east from the volcano from 27 April till 03 May; a thermal anomaly over the lava dome all week.

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

The activity of the volcano continues. Ash explosions up to 26,200 ft (8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 30 April and 01 May; an ash plume extended for about 52 km to the east from the volcano on 01 May.

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

A moderate activity of the volcano continues. Strong 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 gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano all week.

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

The activity of the volcano continues. Ash explosions up to 19,700-26,200 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

A moderate explosive activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds.

KAMBALNY VOLCANO (CAVW #300010)
51.31 N, 156.88 E; Elevation 7072 ft (2156 m)
Aviation Color Code is YELLOW

A gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft. Remains a danger of ash explosions up to 19,700-26,200 ft (6-8 km) a.s.l.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds.

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.
