August 26, 2010, 22:30 UTC (August 27, 2010, 10:30 KDT)
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
> 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 and moderate gas-steam with ash activity of the volcano were observing on August 20-21. Clouds obscured the volcano in the other days of week. Lava flow continues to effusing at the south-western flank of the volcano. According to satellite data, a big bright thermal anomaly was registering over the volcano all week. Ash plumes extended up to 200 km (121 mi) to the south-east from the volcano on August 20.

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, ash plumes up to 8.5 km (27,900 ft) probably occurred on August 20-24. According to visual data, moderate gas-steam plumes with ash were observed on August 20-21, clouds obscured the volcano all week. According to satellite data, a thermal anomaly was registering over the lava dome on August 20, 21, 22, 24.

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 3.8 km (12,500 ft) ASL. According to satellite data, a thermal anomaly was registering over the volcano on August 20, 23-24.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
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 registering. According to visual data, moderate gas-steam activity was observed on August 20. According to satellite data, a thermal anomaly over the volcano was registering on August 23, clouds obscured the volcano during other days.

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 observing on August 21, clouds obscured the volcano in the other days of week. According to satellite data, the thermal anomaly was registering on August 23, clouds obscured the volcano during other days.

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.
