CURRENT CHANGES IN AVIATION COLOR CODE:
KAMCHATKA
AVIATION COLOR CODE OF KLYUCHEVSKOY IS ORANGE
AVIATION COLOR CODE OF KIZIMEN IS YELLOW

KLYUCHEVSKOY VOLCANO (1000-26)
56°03'N, 160°39'E; Elevation 15,580 ft (4,750 m)
AVIATION COLOR CODE IS ORANGE
PREVIOUS AVIATION COLOR CODE WAS YELLOW

Long explosive eruption gradually is finishing. Strong fumarolic activity of the volcano continues but separate ash plumes can occur. Gas-steam plumes containing some amount of ash could affect low-flying and sometimes international aircraft.

Seismicity of the volcano didn't exceeded background levels all week. According to visual data, strong fumarolic activity of the volcano was observed all week; ash plume rose up to 5.0 km (16,400 ft) ASL on November 24. A weak thermal anomaly over the volcanic crater was registered on satellite images on November 19-21. A gas-steam plume extended about 111 km (69 mi) to the north-east from the volcano on November 24.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
CURRENT AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE WAS GREEN

Several new fumaroles were formed at Kizimen volcano in middle of November 2010. Possibly fumarolic activity of the volcano will increasing. Aerosol plumes could affect low-flying aircraft.

Seismicity of the volcano was above background levels all week. According to the visual data by volcanologists, who flew with helicopter around the volcano on November 20, several new fumaroles were detected at summit and south-western flank of the volcano. A small amount of volcanic dust covered south-western flank of the volcano. Probably this dust was formed in time of new fumaroles elaboration. Activity of old fumarole "Revuschaya" (well-known from 1960) at the north-eastern volcanic flank decreased. Thermal anomaly was not noted 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

Growth of the lava dome and ash emission constrained with this continues. Ash explosions up to 10 km (or 32,800 ft) 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, possibly, ash plumes rose up to 3.8 km (12,500 ft) ASL all week. According to visual data, strong gas-steam activity of the volcano was observed on November 19, 20, 22 and 24. Ash plumes rose up to 5.8 km (19,024 ft) ASL in these days. Clouds obscured the volcano on the other days of week. According to satellite data, bright thermal anomaly over the lava dome was registered all week. Ash plumes extending about 408 km (253 mi) mainly to the eastern and southern directions from the volcano were noted on satellite images on November 19-20 and 23-24.

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 6.0 km (or 19,700 ft) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.

Seismicity of the volcano was above background levels all week. Based on seismicity, it is possible that ash plumes rose up to 5.5 km (18,040 ft) ASL on November 20-24. According to the visual data by volcanologists, who flew with helicopter around the volcano on November 20, moderate gas-steam activity of the volcano was noted. Slopes near top of the volcano were covered with ash. According to satellite data, a thermal anomaly was registered over the volcano all week. Gas-steam plume extending 15 km to the south-east from the volcano was detected on November 22.

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. At present, aerosol plumes from the volcano could affect low-flying aircraft.

Seismicity of the volcano was above background levels all week, volcanic tremor continues to be recorded. According to visual data, weak or moderate gas-steam emissions were observed on November 19-22; clouds obscured the volcano on the other days of week. According to satellite data, a weak thermal anomaly was registered over the volcano on November 19 and 21-22.

BEZYMIANNY VOLCANO (1000-25)
55°58'N, 160°36'E; Elevation 9,455 ft (2,882 m)
AVIATION COLOR CODE IS YELLOW

Growth of the lava dome of the volcano continues and aerosol plumes could affect low-flying aircraft.

Seismicity of the volcano was above background levels on November 23-24, and did not exceed background levels on the other days of week. According to visual data, moderate gas-steam emissions were observed all week. According to satellite data, a weak thermal anomaly was registered over the volcano on November 9-22 and 24-25.

BEGINNING IN NOVEMBER 2010, KVERT WILL ASSIGN AN AVIATION COLOR CODE FOR 22 ADDITIONAL VOLCANOES OF KAMCHATKA AND THE NORTHERN KURILES. THESE VOLCANOES ARE NOT PRESENTLY MONITORED WITH SEISMIC INSTRUMENTS HOWEVER 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.

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). 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 10 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
