Scientists of KVERT Project return to the full KVERT operations (the information ensuring of air services for the results of daily analysis and evaluation of activity of Kamchatka and Northern Kuriles volcanoes) and will discharge these obligations for 01 February - 30 April 2010

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 6.8 km (22,300 ft) ASL on March 06 and 08, and up to 5.0 km (16,400 ft) ASL in the other days of week. Strombolian activity of the volcano continues. A height of bursts was about 300 m above the crater. An effusion of new lava flows on the north-eastern and southern volcanic flanks were noted on March 04. A length of a southern flow was about 1.3 km on March 09 (Terra ASTER image). Phreatic bursts sometimes were observed at fronts of these lava flows. According to satellite data, a big thermal anomaly was registering over the volcano all week. Gas-steam plumes extending about 80 km (50 mi) to the eastern directions from the volcano were noted on March 05-06 and 08.

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 6.4 km (21,000 ft) ASL last week. According to visual data, an ash plume rose up to 5.5 km (18,040 ft) ASL on March 10. Moderate gas-steam plumes sometimes containing ash were noting all week. Plumes rose up to 2.5-3.5 km (8,200-11,500 ft) ASL. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plumes extended about 130 km (18.6 mi) to the east-south-east from the dome all 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 obscured seismic data of Bezymianny last week. Moderate fumarolic activity of the volcano was observed on March 05-08 and 10-11. Clouds obscured the volcano on March 09. According to satellite data, a weak thermal anomaly over the lava dome was registering all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
CURRENT AVIATION COLOR CODE IS YELLOW
Weak activity of the volcano continues but ash plumes were not observing last time and a thermal anomaly over the volcano was small and weak. But possibility of ash explosions up to 6.0 km (or 19,700 ft) ASL remains. The explosive activity of the volcano could affect low-flying aircraft.
Seismic activity of the volcano was slightly above background levels all 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 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.
