VONA/KVERT WEEKLY INFORMATION RELEASE 16-2018
Kamchatkan and Northern Kuriles Volcanic Activity

April 19, 2018, 21:09 UTC (April 20, 2018, 09:09 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 COLOUR CODES:

SHEVELUCH VOLCANO (CAVW #300270)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Colour Code is ORANGE


A moderate gas-steam activity 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 moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 14-18 April, the volcano was obscured by clouds in the other days of week.

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


A moderate activity of the volcano continues. Ash explosions up to 16,400-23,000 ft (5-7 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.

An activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds last week.

EBEKO VOLCANO (CAVW #290380)
50.69 N, 156.01 E; Elevation 3792 ft (1156 m)
Aviation Colour 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 2.6 km a.s.l. on 15 and 17-19 April. Satellite data by KVERT showed the volcano was quiet or obscured by clouds.

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.
