SUMMARY OF AVIATION COLOR
CODES:
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, GORELY, MUTNOVSKY and
KIZIMEN: GREEN
NORTHERN
KURILES:
EBEKO, CHIKURACHKI and ALAID: GREEN
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 4.5 km (14,800 ft) ASL all week. According to video data, moderate fumarolic activity was observed all week. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Gas-steam plumes containing small amount of ash extending about 70 km (43 mi) to the eastern directions were noted on November 27-28 and 30.

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, Strombolian activity of the volcano continued all week. A height of bursts was about 300 m above the crater. An effusion of a lava flow on the east-south-eastern volcanic flank continues. 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 27-30 and December 01. There was no seismic data by technical reasons in the other days of week. According to seismic data, possibly ash plumes rose up to 3.0-5.5 km (9,840-18,040 ft) ASL. According to satellite data, a thermal anomaly was registering over the volcano all week. Ash plumes extending about 165 km (102 mi) to the eastern directions from the volcano were noted on November 29-30 and December 01-02.

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 all week. According to satellite data, weak thermal anomaly was registering on November 29-30 and December 01. 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.
