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, gas-steam plumes rose up to 6.7 km (22,000 ft) ASL on February 12-16. Strombolian activity of the volcano continues. A height of bursts was about 200 m above the crater. Clouds obscured the volcano in the other days. An effusion of two lava flows on the north-western volcanic flank (Krestovsky chute and some to south), continues. Phreatic bursts sometimes were observed at a front of these lava flows. According to satellite data, a big thermal anomaly was registering over the volcano all week. Strong gas-steam plumes extended about 243 km (150.7 mi) to the north-east from the volcano all week.

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 5.1 km (16,700 ft) ASL last week. According to visual data, moderate fumarolic activity of the volcano was observing on February 12-16, clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Gas-steam plumes extended >71 km (44.1 mi) to the northern directions from the volcano on February 11, 13 and 17.

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 February 11-14 and was at background levels in the other days of week. According to seismic data, possibly weak ash-gas bursts occurred last week. According to satellite data, a weak thermal anomaly was registering over the volcano on February 11-15. 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.
Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny last week. Strong fumarolic activity of the volcano was observed on February 12-13 and moderate - on February 14-16. Clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly over the lava dome was registering all week. Gas-steam plumes extending to the eastern directions from the volcano were noted on February 12-16.

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.
