KAMCHATKA:
KLYUCHEVSKOY: RED
SHEVELUCH and KARYMSKY: ORANGE
GORELY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY,

CURRENT CHANGES IN AVIATION COLOR CODE
KLYUCHEVSKOY IS NOW AT AVIATION COLOR CODE: ORANGE
KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
CURRENT AVIATION COLOR CODE IS RED
PREVIOUS AVIATION COLOR CODE IS ORANGE
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.
Activity of the volcano increased again. Seismicity of the volcano is very unstable: a magnitude of volcanic tremor is changing sometimes from 5 to 30 mps. According to visual data at present time, ash plumes are raising up to 8.0-8.5 km (27,900 ft) ASL. Ash plumes are extending to the south-east from the volcano. Possibly activity of the volcano will increase.

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 on October 14-16 and did not exceed levels of registration in the other days of week. According to seismic data, possibly ash plumes rose up to 3.8 km (17,050-19,680 ft) ASL on October 14. According to visual data, weak and moderate gas-steam plumes sometimes containing ash were observed on October 15-18; 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 72 km (or 44.6 mi) to the south-east from the volcano on October 15-16.

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 2.0-4.0 km (6,560-13,120 ft) ASL this week. According to visual data by volcanologists who worked at the volcano, ash plumes raising up to 2.5-3.0 km (8,200-9,840 ft) ASL were observed on October 14-16 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 15-16 and 18-19.

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, gas-steam plumes rose up to 2.8 km (9,200 ft) ASL on October 15-16 and 21; clouds obscured the volcano on the other days of week. According to satellite data, a thermal anomaly was registered over the volcano on October 15-16.

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 15-17; 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 15, 17 and 18; 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.
