KVERT WEEKLY INFORMATION RELEASE 51-2019 Kamchatkan and Kuriles Volcanic Activity December 20, 2019, 00:39 UTC (December 20, 2019, 12:39 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 BEZYMIANNY, KLYUCHEVSKOY, SHEVELUCH: ORANGE KARYMSKY: 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, ANTSIFEROVA, 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 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 accompanies this process. Satellite data showed a thermal anomaly over the volcano 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 activity 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 gas-steam activity of the volcano continues. Strombolian activity of the volcano was observed on 13-15 and 17 December. Satellite data showed a weak thermal anomaly above the crater on 12-15 and 17 December; on 14 and 19 December, gas-steam plume on the height about 5.0-5.5 km a.s.l. extended for 45 km to the northeast of the volcano. The volcano was quiet or obscured by clouds during other days of the week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Klyuchevskoy BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 9453 ft (2882 m) Aviation Colour Code is ORANGE Activity of the volcano gradually increases. Strong 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 moderate gas-steam activity of the volcano continues. Satellite data showed a thermal anomaly above the lava dome all week; a temperature of the anomaly was gradually rosing. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Bezymianny 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 eruptive activity of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 3 km a.s.l. on 15-17 December; ash clouds drifted to the eastern directions of the volcano. Ashfalls were noted at Severo-Kurilsk on 16-17 December. Satellite data showed the volcano was quiet or obscured by clouds. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Ebeko KARYMSKY VOLCANO (CAVW #300130) 54.05 N, 159.44 E; Elevation 4874 ft (1486 m) Aviation Colour Code is YELLOW A moderate gas-steam activity of the volcano continues. The danger of ash explosions up to 13,100-19,700 ft (4-6 km) a.s.l. remains. Ongoing activity could affect low-flying aircraft. A moderate gas-steam activity of the volcano continues. Satellite data showed a weak thermal anomaly above the crater on 12 and 17 December, the volcano was quiet or obscured by clouds during other days of the week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Karymsky IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A. Girina, Head of KVERT, IVS FEB RAS E-mail: girina@kscnet.ru Tel.: +74152202044 Tel. 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.
