SUMMARY OF AVIATION COLOR CODES:
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
GORELY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY and KIZIMEN: GREEN
NORTHERN KURILES:
CHIKURACHKI, EBEKO and ALAID: GREEN
KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
AVIATION COLOR CODE IS ORANGE
Explosive-effusive eruption of the volcano continues. Ash explosions >7.0 km (>23,000 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Seismicity of the volcano was above background levels all week. According to visual data, Strombolian activity was observed on October 02-07. Gas-steam plumes containing ash rose up to 6.3 km (20,700 ft) ASL all week. A lava flow continues to effused from the summit crater down the south-western flank of the volcano. According to satellite data, a big bright thermal anomaly was registered over the volcano all week. Ash plumes extended about 50 km (31 mi) to the south-east from the volcano on October 05-06.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive eruption of the volcano continues. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Seismicity was above background levels last week. According to seismic data, moderate ash plumes occurred all week; possibly ash plumes rose up to 6.5 km (21,300 ft) ASL on October 05-07. According to visual data, strong and moderate gas-steam plumes sometimes containing ash were observed on October 03-07; clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the lava dome all week. Gas-steam plumes extended about 190 km (118 mi) to the south-east from the volcano on October 02-03.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions > 6.0 km
(> 19,700 ft) ASL could occur at any time. Aactivity of the volcano
could affect low-flying aircraft.
Seismicity of the volcano was above background levels all week. According to seismic data, possibly weak ash explosions occurred at the volcano all week but ash plumes rose up to 3.0 and 5.1 km (9,840-16,700 ft) on October 03 and 04, respectively. According to satellite data, a thermal anomaly was registered over the volcano on October 04-05. An ash plume extended about 33 km (20 mi) to the south-east from the volcano on October 07.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano is increasing. Probably an eruption of Gorely is preparing. 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 activity of the volcano was observed on October 02-07; clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the volcano on October 02 and 05.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW
Grows of the lava dome of the volcano continues and aerosol plumes could affect low-flying aircraft.
Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny all week. According to visual data, moderate gas-steam activity of the volcano was observed on October 05-07. Clouds obscured the volcano on the other days of week. According to satellite data, a weak thermal anomaly was registered over the lava dome on October 02-06, clouds obscured the volcano on the other days of week.

The Kamchatkan Volcanic Eruption Response Team (KVERT) 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.
