SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION COLOR CODE IS RED
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.
Separate ash explosions at the volcano continues. Ash plumes rose up to 7 km (23,000 ft) ASL at 17:24-18:09 UTC on October 28. Seismicity of the volcano did not exceed background levels on October 21-25. Seismic activity began to increase on October 26, and the strong paroxysmal explosive eruption of the volcano occurred from 14:00 till 20:40 UTC on October 27. According to satellite data by P. Webley (AVO USGS), an eruptive column rose higher than 12 km (39,360 ft) ASL. A large ash plume was observing in breach in the meteorological clouds at Klyuchi village. Ash falls were noted at Ust-Kamchatsk from 18:00 UTC on October 27 till 03:00 UTC on October 28. The airport and road from Ust-Kamchatsk to Kluchi were closed. The thickness of a layer of ash with snow was about 2 cm at Ust-Kamchatsk. According to satellite data, ash plumes extended > 2,500 km (1,550 mi) to the east from the volcano on October 27-28.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
CURRENT AVIATION COLOR CODE IS RED
Explosive-effusive eruption of the volcano continues. Ash explosions >10.0 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 all week. Ash plumes rose up to 8-9 km (26,200-29,500 ft) ASL on October 22-25 and 27. According to satellite data, two lava flows continues to effuse from the terminal crater down the western and south-western flanks of the volcano. A big bright thermal anomaly was registered over the volcano all week. Ash plumes extended > 2300 km (1426 mi) mainly to the east from the volcano all week.

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 on October 21-23 and did not exceed background levels in the other days. According to satellite data, a thermal anomaly was registered over the volcano on October 22-25. Ash plumes extended about 40 km (25 mi) to the east from the volcano on October 23.

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 23, 23-25 and 27; clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the volcano on October 25.

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 22 and 24-25. 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 23-25; 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.
