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:
EBEKO, CHIKURACHKI 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
> 10.0 km (> 32,800 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 September 11. Ash plumes up to 6 km (19,700 ft) ASL occurred on September 11 and 13-14. A lava flow continues to descend 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 reached 7 km (23,000 ft) ASL and extended up to 575 km (354 mi) to the south and south-east from the volcano on September 09-15.

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 all week, and according to seismic data, ash plumes up to 4.5 km (14,760 ft) probably occurred during this week. According to visual data, moderate gas-steam plumes with ash were observed on September 12-15, clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the lava dome.

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 was above background levels all week. According to seismic data, possibly ash plumes rose up to 3.2 km (10,500 ft) ASL on September 15. According to satellite data, a thermal anomaly was registered over the volcano on September 10-11 and 14.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
Seismic and thermal activity of the volcano remains high. 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, moderate gas-steam activity was observed on September 09.

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 clouds obscured the volcano during this 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.
