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.
Moderate seismic activity of the volcano continues. According to seismic data, probably ash plumes rose up to 14,760-16,400 ft (4.5-5.0 km) ASL on October 05-06. According to visual data, ash plumes rose up to 16,400 ft (5.0 km) ASL on October 05-06; strong fumarole activity was observing in these days too. Ash plumes extending about 62 mi (100 km) to the north-east from the volcano were noted on October 06 at the satellite images. A big bright thermal anomaly began to noted over the lava dome from October 05.

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.
Probably the eruption of the volcano go to finish. Seismic activity of the volcano was decreasing to October 05-06: numbers of volcanic earthquakes reduced from 1300 to 500-700; a magnitude of volcanic tremor - from 2.0 to 0.4-0.5 mcm/s. According to video data, a large lava flow continues to effuse on the north-eastern volcanic flank; strong fumarole activity was observing on September 29-30 and October 03-06. Clouds obscured the volcano in the other days of week. A thermal anomaly was registering over the volcano all week at satellite images but a temperature of anomaly began to decreasing.

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 10,500 ft (3.2 km) ASL all week. According to satellite data, a thermal anomaly was registering over the volcano on October 04-05.

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 is possible. Ash and aerosol plumes could affect low-flying aircraft.
Seismic activity was very low all week. Clouds obscured the volcano all week. A weak thermal anomaly over the volcano was noted at satellite images on September 30 and October 04-05.

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. Clouds obscured the volcano all week. A weak thermal anomaly over the volcano was noted at satellite images on October 05.

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.
