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 containing small amount of ash rose up to 6.3 km (20,700 ft) ASL on April 07. Strombolian activity of the volcano continues. A height of bursts was about 200 m above the crater on April 07-08. An effusion of lava flows on the volcanic flanks continues. 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. Narrow ash plume extending about 55-60 km (34-37 mi) to the north-east from the volcano was registered on April 08. Gas-steam plumes extending about 30-180 km (18-110 mi) to the north north-east mainly from the volcano were noted 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
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 (21,300 ft) ASL on April 05 and 08. According to visual data, ash plumes from hot avalanches rose up to 6.1 km (20,010 ft) ASL on April 05 and 08. Strong fumarolic activity of the dome was noting all week. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plume extending about 100 km (62 mi) to the south-east from the dome was noted on April 05.

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 01-03 and at background level in the other days of week. According to seismic data, ash plumes rose up to 3.3 km (10,800 ft) ASL on April 01. According to satellite data, a thermal anomaly was registering over the volcano on April 03-04 and 06.

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 April 04-08, 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 03-07.

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.
