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 7.5 km (24,600 ft) ASL last week. According to visual data, ash plumes rose up to 4.0-5.0 km (13,100-16,400 ft) ASL and extended to the south from the volcano on December 31. Ash fall was noting at Klyuchi village on January 04. Moderate fumarolic activity was observing on December 30-31 and January 01 and 06, clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly was registering over the lava dome all week. A gas-steam plume about 40 km (25 mi) extending to the south-west from the volcano was noted on January 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 on December 30-31 and January 05-06, Strombolian activity of the volcano continues. A height of bursts was about 500 m above the crater. An effusion of a lava flow on the east-south-eastern volcanic flank continues too. An effusion of new lava flow on the north-western volcanic flank (Krestovsky chute), probably, began on January 02-03. 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. Three lava flows were observed on satellite image ASTER on January 05: two on the east-south-eastern volcanic flank and one on the north-western flank.

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 satellite data, a thermal anomaly was registering over the volcano on December 30-31 and January 01 and 04-07. Clouds obscured the volcano in the other days of week.

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.
Seismic activity of the volcano didn't exceeded background levels on December 30-31 and January 01-03. Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny during other days of week. Moderate fumarolic activity of the volcano was observing on December 30-31 and January 04-06, clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly over the dome was registering 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.
