SUMMARY OF AVIATION
COLOR CODES:
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY,
GORELY, MUTNOVSKY and KIZIMEN: GREEN

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. 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 visual data, gas-steam plumes containing ash rose up to 5.7 km (18,700 ft) ASL all week. According to satellite data, a big thermal anomaly was registering over the volcano all week. Weak ash plumes extended about 45 km (28 mi) to the south on April 18. Gas-steam plume extended about 90-100 km (55-60 mi) to the east from the volcano on April 20-21.

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 4.0-6.9 km (13,100-22,630 ft) ASL on April 15-17 and 20-21. According to visual data, a height of an ash explosion was 7.0 km (23,000 ft) ASL on April 18. Ash plumes from hot avalanches rose up to 4.0 km (13,100 ft) ASL all week. Strong and moderate fumarolic activity of the dome was noting all week too. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Weak ash plumes extending about 50-220 km (30-136 mi) to the south-east from the dome were noted on April 18 and 20-21.

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 17-22 and at background levels in the other days of week. According to seismic data, possibly weak ash plumes rose up to 2.0 km (6,500 ft) ASL on April 17 and 18. According to satellite data, a thermal anomaly was registering over the volcano on April 17-22. Ash plumes extending about 40-130 km (25-80 mi) to the south-east from the volcano were noted on April 17 and 21. 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 18-22, 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 17-22.

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.
