VONA/KVERT WEEKLY INFORMATION RELEASE 19-2017 Kamchatkan and Northern Kuriles Volcanic Activity May 12, 2017, 02:35 UTC (May 12, 2017, 14:35 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, KLYUCHEVSKOY, SHEVELUCH: ORANGE KAMBALNY: YELLOW AVACHINSKY, DIKY GREBEN, GAMCHEN, GORELY, ICHINSKY, ILIINSKY, KARYMSKY, 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 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 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. Satellite data by KVERT showed: explosions sent ash up to 10 km a.s.l. on 11 May, a large ash cloud continues to move to the north-west from the volcano; on 08 and 10 May small ash clouds drifted for about 90 km to the north-north-east and north-west from the volcano, respectively; a thermal anomaly was noting over the lava dome all week. 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 The activity of the volcano continues. Ash explosions up to 26,200 ft (8 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: on 05-06 and 10-11 May ash plumes extended for about 270 km to the south-east and north-west from the volcano, respectively; a weak thermal anomaly over the volcano was noted on 05 and 10 May; 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 moderate activity of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. A gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano on 05 and 08-09 May, the volcano was obscured by clouds in the other days of week. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Bezymianny 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 explosive activity of the volcano continues. Satellite data by KVERT showed an ash cloud drifted for about 50 km to the north-east from the volcano on 07 May. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Ebeko KAMBALNY VOLCANO (CAVW #300010) 51.31 N, 156.88 E; Elevation 7072 ft (2156 m) Aviation Color Code is YELLOW A gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft. Remains a danger of ash explosions up to 19,700-26,200 ft (6-8 km) a.s.l. A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds last week. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Kambalny IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A.
