Activity of the volcano continues (the lava flow is effusing on the southern flank of the lava dome) and ash explosions up to 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: a big number of volcanic earthquakes and an intermittent volcanic tremor were registered at the area of the the volcano. According to seismic data, ash plumes rose up to 6.8 km (22,300 ft) ASL past week. According to visual data, hot avalanches were observing at the lava dome on November 06. These avalanches generated ash plumes which rose up to 4.0 km (13,100 ft) ASL. A moderate fumarolic activity of the dome was observed on web-camera on November 08,10 and 12. Clouds obscured the volcano in the other days of the week. According to satellite data, a big thermal anomaly was registered over the lava dome all week. An ash plume extending about 30 km (18.6 mi) to the east from the volcano was noted on November 10. Gas-steam plumes about 50 km long were observed on November 10.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE

A Strombolian activity of the volcano continues. Possibly a lava flow will effuse to a volcanic slope in the near future. Moreover, an explosive process could increase at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of the volcano was above background levels: a lot of volcanic earthquakes and continuous volcanic tremor were registered at the volcano all week. According to video and visual data, gas-steam plumes containing small amount of ash rose up to 300 m above the terminal crater on November 08 and 10-12. Clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registered over the volcano all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE

Activity of the volcano continues and ash explosions up to 6 km (or 19,700 ft.) ASL are possible. The explosive activity of the volcano could affect low-flying aircraft.

Seismic activity of the volcano was above background levels on November 11-12, and at background levels on November 07 and 10. There was not seismic data about technical reasons on November 08-09. According to seismic data, possibly ash-gas explosions up to 3.8 km (12,500 ft) ASL occurred at the volcano on November 11-12. According to satellite data, a thermal anomaly was registered over the volcano on November 10-11. An ash plume extending 38 km (23.6 mi) to the east from the volcano was observed on November 10. An ash cloud was noted in 28 km (17.4 mi) from the volcano to the east-north-east. Clouds obscured the volcano on the other days of the week.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW

Growth of the lava dome continues - possibly a viscous lava flow continues to effusing to the south-southeast flank of the dome. Sudden ash emission related to this activity could affect low-flying aircraft in the vicinity of the volcano.

Strong seismicity of Klyuchevskoy volcano does not allow to detach a seismicity of Bezymianny volcano. A weak fumarolic activity of the volcano was observed on web-camera on November 08 and 11-12. Clouds obscured the volcano in the other days of the week. According to satellite data, a weak thermal anomaly was registered over the lava dome on November 08-11.

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.
