VONA/KVERT WEEKLY INFORMATION RELEASE 24-2017 Kamchatkan and Northern Kuriles Volcanic Activity June 16, 2017, 02:44 UTC (June 16, 2017, 14:44 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 COLOR CODES: KAMCHATKA BEZYMIANNY, KARYMSKY, KLYUCHEVSKOY, SHEVELUCH: ORANGE 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 Color 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 flow reveal in the northern its part), strong fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany this process. According to video and satellite data by KVERT, the power explosive eruption began at 1625 UTC on 14 June: explosions sent ash up to 12 km a.s.l., ash clouds extended for about 1000 km to the north-east and south-west from the volcano on 14-16 June. Ash falls were noted at Klyuchi, Maiskoe, Kozyrevsk and Atlasovo Villages. On 10-13 June, explosions sent ash up to 8 km a.s.l. and ash clouds drifted for about 1500 km to the south-east and north-west from the volcano. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Sheveluch KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 15580 ft (4750 m) Aviation Color Code is ORANGE Explosive eruption of the volcano continues. Ash explosions up to 26,200-32,800 ft (8-10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. Explosive eruption of the volcano continues. According to satellite data by KVERT, a weak thermal anomaly over the volcano was noted on 11-16 June. Explosions sent ash up to 6-7 km a.s.l. all week, and ash plumes drifted for about 580 km to the south-west and south-east from the volcano. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Klyuchevskoy BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 9453 ft (2882 m) Aviation Color Code is ORANGE Activity of the volcano is gradually increasing. 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 activity of the volcano continues. Satellite data by KVERT showed some increase of temperature of thermal anomaly over the volcano. According to video data by KB EGS RAS, a gas-steam plume up to 4 km a.s.l. and hot avalanches from the lava dome were observing on 15 June. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Bezymianny KARYMSKY VOLCANO (CAVW #300130) 54.05 N, 159.44 E; Elevation 4874 ft (1486 m) Aviation Color Code is ORANGE Moderate eruptive activity of the volcano 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. A moderate eruptive activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano on 10-12 and 14-15 June. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Karymsky EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 3792 ft (1156 m) Aviation Color Code is ORANGE A moderate gas-steam with some amount of ash activity of the volcano continues. Ash explosions up to 16,400 ft (5 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk. According to the data by observers from Severo-Kurilsk (Paramushir Island, Northern Kuriles), a moderate explosive activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Ebeko IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A.
