VONA/KVERT WEEKLY INFORMATION RELEASE 42-2017
Kamchatkan and Northern Kuriles Volcanic Activity
October 19, 2017, 23:25 UTC (October 20, 2017, 11:25 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
SHEVELUCH: ORANGE
BEZYMIANNY, KARYMSKY: YELLOW

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 on 15-19 October. The plume of resuspended ash was blowing from the vicinity of the volcano area drifted for about 230 km to the east from the volcano on 13 October.

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 visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 2.5 km a.s.l. all weak. Satellite data by KVERT showed the volcano was quiet or obscured by clouds.

BEZYMIANNY VOLCANO (CAVW #300250)
55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW

A gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano all week.

KARYMSKY VOLCANO (CAVW #300130)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is YELLOW

A moderate gas-steam activity of the volcano continues. A danger of ash explosions up to 16,400-23,000 ft (5-7 km) a.s.l. is remains. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed: the plume of resuspended ash was blowing from the vicinity of the volcano area drifted for about 80 km to the east from the volcano on 14 October.

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 was 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); 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 Northern Kuriles Volcanoes.
