KAMBALNY VOLCANO (CAVW #300010) 51.31 N, 156.88 E; Elevation 7072 ft (2156 m) Aviation Color Code is ORANGE A moderate eruptive activity of the volcano continues. Satellite data by KVERT showed an ash plume extended for about 90 km to the south-east from the volcano. EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 3792 ft (1156 m) Aviation Color Code is ORANGE A moderate activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet. KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 15580 ft (4750 m) Aviation Color Code is YELLOW A gas-steam activity of the volcano continues.

VONA/KVERT WEEKLY INFORMATION RELEASE 14-2017 Kamchatkan and Northern Kuriles Volcanic Activity April 06, 2017, 08:52 UTC (April 06, 2017, 20:52 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, KAMBALNY, KLYUCHEVSKOY, SHEVELUCH: ORANGE 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 a thermal anomaly over the lava dome all week; ash clouds drifted for about 20 km to the south-east from the volcano on 03 April. 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 explosive eruption of the volcano continues. Ash explosions up to 19,700-26,200 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. The moderate activity of the volcano continues. Explosions sent ash up to 5-6 km a.s.l. on 01-04 April. Satellite data by KVERT showed a thermal anomaly over the volcano 01-02 and 04 April; ash plume drifted for about 400 km to the north-west, east, north-east 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 A moderate activity of the volcano continues. 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 gas-steam activity of the volcano continues. Effusing of the lava flow occur at the north-western flank on 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 KAMBALNY VOLCANO (CAVW #300010) 51.31 N, 156.88 E; Elevation 7072 ft (2156 m) Aviation Color Code is ORANGE The activity of the volcano continues. Ash explosions up to 19,700-26,200 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. The explosive eruption of the volcano continues. Satellite data by KVERT showed the volcano was quiet on 01 April; explosions sent ash up to 7 km a.s.l. on 02 April, and a weak emission of ash continues. Ash plumes drifted for about 200 km to the east and south-east from the volcano on 02-04 April. A weak thermal anomaly over the volcano was noted on 03-04 April. http://www.kscnet.ru/ivs/kvert/volc.php?lang=en&name=Kambalny 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. According to the data by observers from Severo-Kurilsk (Paramushir Island, Northern Kuriles), several ash bursts up to 4 km a.s.l. occurred on 04-06 April; a weak ashfall was noted at Severo-Kurilsk on 06 April. 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.
