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
BEZYMIANNY VOLCANO: 55°58'N,
160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE WAS ORANGE
Activity of the volcano continues and its aerosolic plumes could affect low-flying aircraft.
Seismic activity of the volcano significant decreased from December 17, but remains slightly above background levels. Big thermal anomaly over the lava dome of the volcano was registering on December 17-20. According to volcanologists experience, probably a viscous lava flow extrudes from the crater of the lava dome. No visual and video data on December 19-20 because the volcano obscured by clouds. Ash plumes were not noted on the satellite images on December 19-20.

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 last week. According to video data, the volcano was
obscured by clouds all week. 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
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, the volcano was obscured by clouds all 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.
Seismicity of
the volcano was above background levels on December 12-13 and there was no
seismic data by technical reasons in the other days of week. According to
satellite data, a thermal anomaly was registering over the volcano on December
11-13 and 17.

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.
