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 6.2 km (20,300 ft) ASL last week. Clouds obscured the volcano all week. According to satellite data, a big thermal anomaly was registering over the lava dome all week. An ash plume about 08 km (5 mi) extending to the south-west from the volcano was noted on January 13.

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 on January 12-14, gas-steam plumes rose up to 6.8 km (22,300 ft) ASL and extending to the east from the volcano. Strombolian activity of the volcano continues. An effusion of a lava flow on the north-western volcanic flank (Krestovsky chute), continues. A length of the lava flow is about 1.2 km (0.7 mi) at present. Phreatic bursts were observed at a front of this lava flow. 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. One bright lava flow on the north-western volcanic flank was observing on satellite image ASTER on January 13.

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 all week. According to seismic data, possibly ash plumes rose up to 3 km (9,840 ft) ASL last week. According to satellite data, a thermal anomaly was registering over the volcano on January 08 and 10-14. Ash plumes till 113 km (70 mi) extending to the south-east from the volcano were noted on January 12-13.

BEZYMIANNY VOLCANO: 55°58'N,
160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues and its aerosolic plumes could affect low-flying aircraft.
Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny last week. Moderate fumarolic activity of the volcano was observed on January 14, clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly over the lava dome was registering on December 10-13. 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.
