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. Volcanic tremor harsh increased last two days ago. According to visual data, Strombolian activity was observed on October 07-11. Gas-steam plumes containing ash rose up to 7.8 km (25,580 ft) ASL on October 11 and for about 5.8 km (19,000 ft) ASL in the other days. According to the ASTER satellite image (11.10.2010, 00:37 UTC), two lava flows continues to effuse from the terminal crater down the western and south-western flanks of the volcano. According to satellite data, a big bright thermal anomaly was registered over the volcano all week. Ash plumes extended about 90 km (55 mi) to the north-east and east from the volcano on October 10, 12 and 13-14.

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 of the volcano was above background levels last week. According to seismic data, possibly ash plumes rose up to 5.2-6.0 km (17,050-19,680 ft) ASL this week. According to visual data, weak and moderate gas-steam plumes sometimes containing ash were observed on October 07, 09-10 and 12-13; 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. Ash plumes extended about 130 km (or 80 mi) to the south-east from the volcano on October 09-10.

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 ash plumes rose up about 2.0-3.0 km (6,560-9,840 ft) ASL this week. According to visual data from volcanologists who work now at the volcano, ash plumes raising up to 2.5 km (11,500 ft) ASL were observed on October 07-10 and extended to the east, the Strombolian activity of the volcano in the dark time was noted constantly. According to satellite data, a thermal anomaly was registered over the volcano on October 07-10, 12 and 14. Ash plumes extended about 35 km (22 mi) to the south-east from the volcano on October 07-08.

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 records. According to visual data, weak or moderate gas-steam activity of the volcano was observed on October 10 and 13-15; clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the volcano on October 10 and 13.

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 07 and 10. 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 09-10; 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.
