VONA/KVERT WEEKLY INFORMATION RELEASE 33-2017 Kamchatkan and Northern Kuriles Volcanic Activity August 18, 2017, 00:22 UTC (August 18, 2017, 12:22 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 satellite data by KVERT, a thermal anomaly over the volcano was noting all week. Ash clouds drifted for about 180 km to the east, north-west and north-east from the volcano on 12 and 15-16 August. 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 Eruptive activity 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. A moderate explosive activity of the volcano continues. Satellite data by KVERT showed ash plumes extended for about 315 km to the east and north-west from the volcano on 11-12 and 15-17 August; the volcano was obscured by clouds in the other days of week. 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 A gas-steam activity of the volcano continues. A danger of strong ash explosions up to 32,800 ft (10 km) a.s.l. is remains. Ongoing activity could affect international and low-flying aircraft. A moderate gas-steam activity of the volcano continues. An incandescence of the lava dome was observing at night, and a lava flow continued to squeezing at the western flank of the lava dome. Satellite data by KVERT showed a thermal anomaly over the volcano all week. 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 A 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 11 August; an ash plume extended for about 400 km to the south-east from the volcano on 12-13 August. 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. A moderate eruptive activity of the volcano probably 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.
