SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION COLOR CODE IS
ORANGE
Activity of the volcano continues: a new viscous lava flow effuses at the lava dome. 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. According to seismic data, possibly ash plumes rose up to 5.3 km (17,400 ft) ASL all week. According to video data, moderate fumarolic activity was observed on November 14-15, clouds obscured the volcano in the other days of week. According to infrared video data, hot avalanches were noted in dark time on November 14-15. According to satellite data, a big thermal anomaly was registering over the lava dome all week.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
AVIATION COLOR CODE IS
ORANGE
Strombolian activity of the volcano continues. Ash explosions > 6.0 km (>19,700 ft)ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Explosive eruption of the volcano began on September 18. Seismicity of the volcano was above background levels all week. According to visual data on November 13-15, Strombolian activity of the volcano continues. A height of bursts was about 200 m above the crater. An effusion of a new lava flow on the east-south-eastern volcanic flank was noted on November 14. A run-out of lava flow was about 500 m. Clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly was registering over the volcano all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
AVIATION COLOR CODE IS
ORANGE
Activity of the volcano continues and ash explosions up to 6.0 km (or 19,700 ft) ASL possible. The explosive activity of the volcano could affect low-flying aircraft.
Seismic activity of the volcano was above background levels on November 12, 14 and 16. There was no seismic data by technical reasons in the other days of week. According to seismic data, possibly ash plumes rose up to 3.0 km (9,900 ft) ASL. According to satellite data, a thermal anomaly was registering over the volcano all week. Ash plumes extending about 132 km (82 mi) to the eastern directions from the volcano were noted on November 12-14 and 17.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS
YELLOW
Growth of the lava dome continues. Sudden ash emission related to this activity could affect low-flying aircraft in the vicinity of the volcano.
Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny all week. According to visual and video data, moderate fumarolic activity of the volcano was noting on November 14-15. According to satellite data, weak thermal anomaly was registering on November 17. Clouds obscured the volcano in 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.
