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 5.5 km (18,000 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. Ash plume extending about 85 km (53 mi) to the south-east from the volcano was noted on December 06.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
AVIATION COLOR CODE IS ORANGE
Explosive-effusive eruption of the volcano continues. Ash explosions > 7.0 km (>23,000 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 all week. According to visual data, Strombolian activity of the volcano continued all week. A height of bursts was about 200-300 m above the crater. Gas-steam plumes containing small amount of ash rose up to 6.3 km (20,700 ft) ASL and extending to the eastern directions were noted on December 05-09. 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. An ash plume extending ~ 10 km (6 mi) to the E from the volcano was noted on December 09.

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.
There was no seismic data by technical reasons almost all week. According to visual data by staff of KB GS RAS on December 08, a new lava flow was noted on the southern flank of the volcano. According to satellite data, a thermal anomaly was registering over the volcano on December 03 and 06-07. Ash deposits extending about 45 km (28 mi) to the south-east from the volcano were noted on December 06.

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 was above background levels on December 08-10 and didn't exceeded background levels on December 03-05. Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny on December 06-07. According to visual and video data, moderate fumarolic activity of the volcano was noting on December 05 and 07. According to satellite data, a weak thermal anomaly was registering on December 03, 05-07 and 09. 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.
