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.
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 remains on the high level. 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.
Seismic activity of the volcano remains on the high level: a magnitude of volcanic tremor continues to increases; 1200-1500 volcanic earthquakes are registering each day. According to video data, strong fumarole activity was observing all week. The lava flow continues to moving on the eastern flank of the volcano. A thermal anomaly was registering over the volcano all week at satellite images.

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 21,300 and 33,800 ft (6.5 and 10.3 km) ASL on September 09 and 11, respectively. According to visual data, ash plumes rose up to 15,400 ft (4.7 km) ASL on September 09; moderate fumarole activity was observing on September 09 and 14; clouds obscured the volcano in the other days of week. A thermal anomaly was registering over the volcano on September 09 and 13, at the 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 15,100 ft (4.6 km) ASL on September 13-14. According to the data by D. Melnikov (KVERT) from the area of the volcano, ash explosions occurred all week; a height of ash plumes was not exceed 11,500 ft (3.5 km) ASL. Ash plumes extending about 80 km to the east and south-east were noted at the satellite images on September 11-12 and 14. A thermal anomaly was registering over the volcano all 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 is possible. Ash and aerosol plumes could affect low-flying aircraft.
Seismic activity was very low all week. According to the data by KVERT-correspondent from the area of the volcano on September 06, the lava flow continues to effusing on the south-south-east volcanic flank. Clouds obscured the volcano last 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. Moderate gas-steam activity of the volcano was observing on September 10-14, clouds obscured the volcano on the other days.

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.
