(10) Summit Elevation:15580 ft (4750 m)(11) Volcanic Activity Summary:According to video data, the Strombolian activity of Klyuchevskoy volcano began to observing from 22:03 UTC on 01 October, 2020, and such activity continues. Explosions send ash up to 300-400 m above the crater of the volcano (about 5 km a.s.l.), a gas-steam plume containing some amount of ash descends along the slope of the volcano towards the east. An ash plume is not detect on the satellite images at this time. \n\nA moderate explosive eruption of the volcano possibly will continues. Ash explosions up to 16,400-19,700 ft (5-6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

KVERT WEEKLY INFORMATION RELEASE 40-2020
Kamchatkan and Kuriles Volcanic Activity
October 01, 2020, 23:37 UTC (October 02, 2020, 11:37 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 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 eastern part of the lava dome and hot avalanches accompanie this process. The new lava block is being extruded out in the eastern part of the lava dome, its composition is the most acsid in the history of the dome growth of Sheveluch (since 1980). Satellite data showed a thermal anomaly over the lava dome all 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 eruption of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 3.5 km a.s.l. on 25-26, and 30 September, and 01 October; ash clouds drifted to the east, and south-east of the volcano. Satellite data showed the volcano was quiet or obscured by clouds last 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 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 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.
