KVERT WEEKLY INFORMATION RELEASE 43-2018
Kamchatkan and Kuriles Volcanic Activity
October 26, 2018, 01:13 UTC (October 26, 2018, 13:13 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.

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 aircrafts.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 20, 22 and 25 October; the volcano was obscured by clouds in the other days of week.

EBEKO VOLCANO (CAVW #290380)
50.69 N, 156.01 E; Elevation 3792 ft (1156 m)
Aviation Colour Code is ORANGE

A moderate eruptive activity of the volcano continues. Ash explosions up to 19,700 ft (6 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 4.7 km a.s.l. all week; ash clouds drifted to the eastern directions from the volcano; ashfalls were noted in Severo-Kurilsk on 19-20 and 23-24 October. Satellite data by KVERT showed a thermal anomaly over the volcano on 24 October; ash clouds drifted for about 80 km to the east from the volcano on 20 October.

48.09 N, 153.2 E; Elevation 4907 ft (1496 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 aircrafts.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet or obscured by clouds all week. KVERT continues to monitor Sarychev Peak volcano.

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.
