Happy New Year! All the Best for the World! KVERT WEEKLY INFORMATION RELEASE 01-2021 Kamchatkan and Kuriles Volcanic Activity January 01, 2021, 00:29 UTC (January 01, 2021, 12:29 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. SUMMARY OF AVIATION COLOUR CODES: KAMCHATKA KARYMSKY, KLYUCHEVSKOY, SHEVELUCH: ORANGE BEZYMIANNY: 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, ANTSIFEROV, CHIKURACHKI, CHIRINKOTAN, EKARMA, FUSS PEAK, KARPINSKY, KRENITSYN PEAK, KUNTOMINTAR, NEMO PEAK, SEVERGIN, SINARKA, TATARINOV: GREEN CENTRAL KURILES GORYASHCHY, PALLAS PEAK, PREVO PEAK, RAIKOKE, RASSHUA, SARYCHEV PEAK, USHISHIR, ZAVARITSKY CALDERA: GREEN SOUTHERN KURILES ATSONUPURI, BARANSKY, BERG, BERUTARUBE, BOGDAN KHMELNITSKY, BRAT CHIRPOEV, CHYORNOGO, GOLOVNIN, IVAN GROZNY, KOLOKOL, KUDRYAVY, MENDELEEV, SNOW, STOKAP, TREZUBETS, TYATYA: 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 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, and an incandescence of the lava dome and hot avalanches accompanie this process. Video and satellite data showed a strong explosive event occured on 29 December. The explosions sent ash up to 7 km a.s.l., and an ash cloud drifted for 250 km to the west of the volcano. A thermal anomaly over the lava dome was registering all week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Sheveluch KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 15580 ft (4750 m) Aviation Colour Code is ORANGE A moderate explosive-effusive eruption of the volcano continues. Ash explosions up to 23,000-26,200 ft (7-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. A moderate explosive-effusive eruption of the volcano continues, the Strombolian and sometimes Vulcanian activity is observing. The lava flow continues to move along Kozyrevsky chute on the southern volcanic flank. Satellite data showed a large bright thermal anomaly in the area of the volcano all week; all week gas-steam plumes containing some amount of ash rose up to 6 km a.s.l., and extended for 250 km to the different directions of the volcano. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Klyuchevskoy KARYMSKY VOLCANO (CAVW #300130) 54.05 N, 159.44 E; Elevation 4874 ft (1486 m) Aviation Colour Code is ORANGE A moderate activity of the volcano continues. The 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 eruptive activity of the volcano continues. Satellite data showed: 26 and 30 December explosions sent ash up to 4-5 km a.s.l., ash clouds drifted for 70 km to the north-west of the volcano; a thermal anomaly over the volcano on 24-28 December, the volcano was quiet or obscured by clouds in the other days of week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Karymsky 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 3.1 km a.s.l. on 25 and 30-31 December; ash clouds drifted to the different directions of the volcano. Satellite data showed the volcano was quiet or obscured by clouds. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Ebeko 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. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Bezymianny IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A.

Duty scientist: +79622825253 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.
