KVERT scientists examined satellite information each day to look for evidence of volcanic unrest since 2002. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.
SHEVELUCH VOLCANO (1000-27)
56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~8,200 ft
(~2,500 m)
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Strong seismic activity of the volcano was registering all week: probably ash plumes rose up to 25,600 ft (7.8 km) ASL on October 29, and less on the other days. According to visual data, strong fumarolic activity was observing at the lava dome on October 29 - November 01; clouds obscured the volcano in the other days of week. According to satellite data, gas-steam plumes containing small amount of ash were extending for about 93 mi (150 km) to the east and south-east from the volcano on October 31 and November 01-02. A big thermal anomaly was noting over the lava dome all week.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
CURRENT AVIATION COLOR CODE IS ORANGE
Activity of the volcano is gradually decreasing but strong ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Moderate seismic activity of the volcano was registering last week: numbers of volcanic earthquakes were changing from 12 to 36; a magnitude of volcanic tremor was 0.3 mcm/s. According to video data, a gas-steam activity of the volcano was observed from October 28 till November 02. Clouds obscured the volcano on the other days of week. The large lava flow continues to effuse on the eastern and north-eastern volcanic flanks - incandescences of the crater of the volcano was noting in a dark time all week. A thermal anomaly was registering over the volcano all week at satellite images.

KARYMSKY VOLCANO (1000-13)
54°03'N, 159°27'E; Elevation 4,874 ft (1,486 m)
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.
Moderate seismic activity of the volcano continues; according to seismic data, possible ash plumes rose up to 14,760 ft (4.5 km) ASL on October 27-30 and November 01-02. According to satellite data, ash plumes extending for about 81 mi (130 km) to the south-east were observed on October 29-30. A thermal anomaly was registering over the volcano was noting on October 29-31 and November 01. Clouds obscured the volcano on the other days of week.

BEZYMIANNY VOLCANO (1000-25)
55°58'N, 160°36'E; Elevation 9,455 ft (2,882 m)
AVIATION COLOR CODE IS YELLOW
Effusion of viscous lava flow at the dome slope continues. Small ash plumes from hot avalanches are possible. Ash and aerosol plumes could affect low-flying aircraft.
Seismic activity was mainly low last week. Strong and moderate fumarolic activity of the volcano was observing on November 02-03, and on October 29 and November 01, respectively; clouds obscured the volcano on the other days. According to satellite data, thermal anomaly over the volcano was noted on the satellite images from October 29 till November 02; a temperature of thermal anomaly over the volcano was slightly increasing last week. Clouds obscured the volcano on the other days of week.

GORELY VOLCANO (1000-07)
52°33'N, 158°02'E; Elevation 5,996 ft (1,828 m)
AVIATION COLOR CODE IS YELLOW
Seismic and thermal activity of the volcano remains high. This ongoing
unrest may eventually lead to an explosive eruption. Aerosol plumes
from the volcano could affect low-flying aircraft.
Moderate seismic activity of the volcano continues and a volcanic tremor was registering at the volcano all week. According to visual data, a moderate gas-steam activity of the volcano was observed from October 29 till November 01; the volcano was obscured by clouds on the other days of week. A weak thermal anomaly over the volcano was noted at satellite images on October 31 and November 01-02.

The KVERT Project is a cooperative program of the Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS since 1993. KVERT scientists is available in the office from 8:30 AM till 6:00 PM (KST) and by phone during the evenings. KVERT uses daily satellite imagery, information from remote scientific observation stations, real-time seismic data for 11 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
