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)
AVIATION COLOR CODE IS ORANGE
Effusive eruption of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) ASL are possible. Ongoing activity could affect international and low-flying aircraft.
KVERT reported in Weekly Release 66-11 about an increasing seismicity of Kizimen last week. Series of strong seismic events were registered on December 13 in period 19:47-20:28 UTC. According to interpretation by KBGS RAS staff, possibly ash explosions were height about 24,600 ft (7.5 km) a.s.l. Video observation of the volcano showed that hot avalanches from the left side of the lava flow began to forming from 16:00 UTC on December 13, and continues possibly at present. Volumes of hot avalanches changed and sometimes large pyroclastic flows were observed. A large pyroclastic flows with co-ignembrite clouds were observed in period 20:20-22:10 UTC on December 13. Ash plumes (generating by pyroclastic flows) rose about 16,400-19,700 (5-6 km) a.s.l. No explosions were noted for all time on December 13-14. Strong gas-steam plume don't elevated to high up the summit of the volcano and moved to the south-east. Ashes from pyroclastic flows mixed with gas-steam and gas-ash plumes on the height about 9,840 ft (3 km) a.s.l. extending 93 mi (about 150 km) from the volcano were noting at satellite images on December 13-14. The large lava flow continues to effuse on the eastern and north-eastern volcanic flanks - a big 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-effusive 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 was registering all week. According to visual data, a viscous lava flow continues to effuse into the explosive crater of 2010 eruption; moderate fumarolic activity was observing at the lava dome on December 10-11 and 13-15; clouds obscured the volcano on the other days of week. According to satellite data, a big thermal anomaly was noting over the lava dome all week.

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 13,500 ft (4.1 km) ASL on December 08-10 and 14. According to satellite data, weak ash plumes were extending about 99 mi (160 km) to the south-east from the volcano were noted on December 12-13. 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 are possible. Ash and aerosol plumes could affect low-flying aircraft.
Seismic activity was mainly low last week. According to visual data, a strong gas-steam activity of the volcano was observed on December 11, clouds obscured the volcano in the other days of week. According to satellite data, weak thermal anomaly over the volcano was noted on the satellite images on December 11-13, clouds obscured the volcano in 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 strong and moderate gas-steam activity of the volcano was observed all week.

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.
