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

COLOR CODES:
KAMCHATKA:
SHEVELUCH and KLYUCHEVSKOY: ORANGE
KARYMSKY and BEZYMIANNY: YELLOW

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 sometimes containing ash rose up to 6.8 km (22,300 ft) ASL on March 18-22, clouds obscured the volcano in the other days of week. Strombolian activity of the volcano continues. A height of bursts was about 100-300 m above the crater. An effusion of lava flows on the volcanic flanks continues. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending about 76 km (47 mi) to the north-east from the volcano were noted on March 21 and 24. Gas-steam plumes spreading about 83 km (51 mi) to the eastern directions from the volcano were registering on March 18-20.

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 explosion up to 7.0 km (23,000 ft) occurred on March 22; ash plumes rose up to 4.2 km (13,800 ft) ASL in the other days of week. According to visual data, strong fumarolic activity was noted on March 20-21, clouds obscured the volcano in the other days of week. Hot avalanches from the lava dome were observing in the dark time. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plume extending about 41 km (25 mi) to the north-east from the dome was noted on March 21.

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 March 19-21, clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly over the lava dome was registering on March 18, 20-21 and 25.

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 and its seismicity slightly increased on March 25. According to satellite data, a weak thermal anomaly was registering over the volcano on March 19-20, 23 and 25, 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.
