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.
CURRENT CHANGES IN AVIATION COLOR CODE:
KAMCHATKA AVIATION COLOR CODE OF KLYUCHEVSKOY IS YELLOW
KLYUCHEVSKOY VOLCANO (1000-26)
56°03'N, 160°39'E; Elevation 15,580 ft (4,750 m)
CURRENT AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE WAS ORANGE
Moderate ash explosions could occur at any time. A height of ash explosions could increases. The activity of the volcano could affect international and low-flying aircraft.
Seismic activity of the volcano continues. According to visual and video data, ash plumes are raising up to 16, 400 ft (5.0 km) ASL and extending to the south-west from the volcano on May 29. The volcano was quiet on May 30, and obscured by clouds on May 31.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
CURRENT AVIATION COLOR CODE IS ORANGE
Eruption of the volcano continues. 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 was above background levels all week. Strong volcanic tremor is registering from May 12; and an amplitude of tremor gradually increasing (from 3.5*10-6 mps on May 18 till 11*10-6 mps on May 24). A bright thermal anomaly was registering over the volcano on May 21-24 and 26 at satellite images.
*****
History of Kizimen eruptions is unknown. We have incomplete data about
only one eruption in 1928-1929 which were likely moderate explosive (or
explosive-effusive) events. Tephrachronological data point out several
catastrophic eruptions in evolution of this volcano.

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.
Seismic activity does not exceed background levels all week. According to visual data, strong gas-steam activity of the volcano was observed on May 21; clouds obscured the volcano on the other days of week. According to satellite data, ash plumes extended about 51 mi (82 km) to the south-west from the volcano on May 20. A thermal anomaly was registered over the lava dome on May 19-21 and 24.

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, possible ash plumes rose up to 11,500 ft (3.5 km) ASL all week and up to 21, 320 ft (6.5 km) ASL on May 21. A thermal anomaly was registering over the volcano on May 19-20, 22 and 24. Ash plumes extending about 23.6 mi (38 km) to the south-west were noted at satellite images on May 22.

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 does not exceed background levels all week. Clouds obscured the volcano all week. According to satellite data, a thermal anomaly over the lava dome was registering on May 19 and 24.
http://www.kscnet.ru/ivs/kvert/current/bzm/index.html
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 weak volcanic tremor was registered at the volcano all week. According to visual data, a moderate gas-steam activity of the volcano was observed on May 20-23, on the other days it was obscured by clouds. A weak thermal anomaly over the volcano was registering on May 22 and 24. Clouds obscured the volcano in the other days.

The KVERT Project is a non-commercial cooperative program of the Alaska Volcano Observatory (AVO, USA), the Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS (Russia) since 1993. KVERT staff is available in the office from 8:30 AM till 6:00 PM (KST or KDT) 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.
