SUMMARY OF AVIATION COLOR
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY,
GORELY, MUTNOVSKY and KIZIMEN: GREEN
NORTHERN KURILES:
EBEKO,
CHIKURACHKI and ALAID: GREEN
CURRENT CHANGES IN AVIATION COLOR CODE
KIZIMEN IS NOW AT AVIATION COLOR CODE: GREEN
KIZIMEN VOLCANO: 55°12'N, 160°32'E; Elevation 2,485
m
CURRENT AVIATION COLOR CODE IS GREEN
PREVIOUS AVIATION COLOR CODE WAS YELLOW
Fumarolic activity of the volcano continues and such activity is normal for the volcano. KVERT continues to watch the Kizimen volcano.
Seismicity was slightly above background levels on November 06, 08 and 10, and didn't exceeded background levels in the other days of week. According to satellite data, the volcano was quiet or obscured by clouds last week.

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 5.5 km (18,040 ft) ASL all week. According to video data, ash plumes rose up to 4.2 km (13,800 ft) ASL on November 05, clouds obscured the volcano in the other days of week. According to infrared video data, hot avalanches were noted in dark time on November 10-12. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plumes extending about 318 km (197 mi) to the east from the volcano were noted on November 11.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
AVIATION COLOR CODE IS ORANGE
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 05, 07 and 10, Strombolian activity of the volcano continues. A height of bursts was about 300 m above the crater, 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 05-09. There was no seismic data by technical reasons on November 10. According to seismic data, possibly ash plumes rose up to 3.7 km (12,100 ft) ASL on November 05-09. According to satellite data, a thermal anomaly was registering over the volcano on November 05-07, 09 and 11-12. Ash plumes extending about 190 km (118 mi) to the east from the volcano were noted on November 08-12.

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.
Seismic activity of the volcano didn't exceeded background levels on November 09-11, and strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny in the other days of week. According to visual, video and satellite data, clouds obscured the volcano all 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.
