KVERT WEEKLY INFORMATION RELEASE 14-2020
Kamchatkan and Kuriles Volcanic Activity
April 02, 2020, 22:13 UTC (April 03, 2020, 10:13 KST)

KVERT monitor active volcanoes of Kamchatka and the Kurile Islands. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

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

The 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 strong fumarolic activity sometimes with some amount of ash, and an incandescence of the dome blocks and hot avalanches accompanie this process. Satellite data showed a thermal anomaly over the volcano all week.

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

A moderate explosive eruption of the volcano continues. Ash explosions up to 16,400-23,000 ft (5-7 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

A moderate explosive eruption of the volcano continues, the Strombolian and gas-steam activity were noted all week. The Vulcanian activity was registered on 29-30 March, ash plumes extended to the northeast and east of the volcano. Satellite data showed a bright thermal anomaly over the summit volcanic crater all week, except 01 April (overcast); ash plumes extended for 455 km to the northeast and east of the volcano on 29-30 March.

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

A moderate explosive eruption 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 eruption of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 2.2 km a.s.l. on 29 and 31 March and 01-02 April; ash clouds drifted to the east and northeast of the volcano; ashfalls were noted at Severo-Kurilsk on 01 April. Satellite data showed a thermal anomaly over the volcano on 30-31 March, 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 gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data showed a thermal anomaly over the lava dome on 26-29 March and 02 April, the volcano was obscured by clouds in the other days of 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 are 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) of Kamchatkan and Kuriles Volcanoes to using the information system (IS) “Remote monitoring of the activity of Kamchatka and Kuriles volcanoes (VolSatView)”, which was created in 2011-2014 the joint efforts of the scientists of KVERT IVS FEB RAS, the Space Research Institute RAS, the Computing Center FEB RAS and the Far Eastern Scientific Center Planet. IS continues to evolve. KVERT 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 Kuriles Volcanoes.
