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. Strombolian activity of the volcano continues. A height of bursts was about 200 m above the crater on April 09-13. An effusion of lava flows on the volcanic flanks continues. Possibly a new chute began to form at south-western flank of the volcano on April 08-09. Strong and moderate gas-steam activity of the volcano was noting all week. According to satellite data, a big thermal anomaly was registering over the volcano all week. Gas-steam plume extended about 86 km (50 mi) to the north-east from the volcano on April 09.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the
dome elevation ~2,500 m
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive eruption of the volcano continues. 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 on April 08 and up to 5.6 km (18,400 ft) in the other days of week. According to visual data, ash plumes from hot avalanches rose up to 3.7 km (12,100 ft) ASL on April 09-13. Strong fumarolic activity of the dome was noting on April 09-13 and 15 too. 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. Gas-steam plume extending about 75 km (46 mi) to the east from the dome was noted on April 13.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions > 6.0 km (or 19,700 ft) ASL could occur at any time. Aactivity of the volcano could affect low-flying aircraft.
Seismic activity of the volcano was above background levels on April 11 and 13-15 and at background levels in the other days of week. According to satellite data, a thermal anomaly was registering over the volcano on April 11-12. 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 obscured seismic data of Bezymianny last week. Moderate fumarolic activity of the volcano was observed on April 08-13, 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 April 08-13.

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.
