KVERT WEEKLY INFORMATION RELEASE 16-2019
Kamchatkan and Kuriles Volcanic Activity
April 18, 2019, 05:45 UTC (April 18, 2019, 17:45 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 COLOUR CODES:

KAMCHATKA
KARYMSKY, SHEVELUCH: ORANGE
BEZYMIANNY, KLYUCHEVSKOY: YELLOW
AVACHINSKY, DIKY GREBEN, GAMCHEN, GORELY, ICHINSKY, ILIINSKY, KAMBALNY, 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 Colour Code is ORANGE

Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800-49,200 ft (10-15 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 blocks extrude out on the northern part of it), a strong fumarolic activity and an incandescence of the dome blocks and hot avalanches accompanies this process. Satellite data showed the thermal anomaly over the volcano all week; ash plumes extended for about 83 km to the south-east from the volcano on 13 and 15 April.

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

A moderate eruptive activity of the volcano continues. Ash explosions up to 13,100-19,700 ft (4-6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircrafts.

A moderate activity of the volcano continues. Satellite data shows a weak thermal anomaly over the volcano on 13-14 April; the volcano was quiet or obscured by clouds in the other days of week.

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

A 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 and airport of Severo-Kurilsk.

A moderate explosive activity of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 3.2 km a.s.l. on 12-15 April. Satellite data shows a thermal anomaly over the volcano on 13 April; the volcano was quiet or obscured by clouds in the other days of week.

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

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

A moderate gas-steam activity of the volcano continues. Satellite data shows: a gas-steam plume containing small amount of ash extended for 33 km to the south-east from the volcano on 15 April; a weak thermal anomaly over the volcano on 12 and 15 April. The volcano was quiet or obscured by clouds in the other days of week.

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

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

A strong gas-steam activity of the volcano continues. Satellite data shows the thermal anomaly over the volcano all week.

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.
