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

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 4.5 km (14,800 ft) ASL last week. According to visual and video data, a movement of many hot avalanches occurred from the lava dome in this week. Deposits of a small pyroclastic flow was noting on the S-E-flank of the volcano. Fumarolic plumes rose up to 2.8-5.0 km (9,200-16,400 ft) ASL on October 16, 18-20 and 22. 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.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
AVIATION COLOR CODE IS ORANGE
Activity of the volcano continues. Ash explosions > 6.0 km (>19,700 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Explosive eruption of the volcano began on September 18.
Seismicity of the volcano was above background levels all week. According to visual data, Strombolian activity of the volcano was observed on October 16 and 18-22. A height of bursts was about 500 m above the crater. Moderate fumarolic activity of the volcano was noted on October 16 and 18-22, clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly was registering over the volcano all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
AVIATION COLOR CODE IS ORANGE
Activity of the volcano continues and ash explosions up to 6.0
km (or 19,700 ft) ASL possible. The explosive activity of the volcano could
affect low-flying aircraft.
Seismic activity of the volcano was above background levels last week. According to seismic data, possibly ash plumes rose up to 3.9 km (12,800 ft) ASL last week. According to satellite data, the volcano was quiet last week.

KORYAKSKY VOLCANO; 53°19'N, 158°43'E; Elevation 3,456
m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues and gas-steam plumes and
possible ash plumes could affect low-flying aircraft.
Seismicity didn't exceeded background levels all week. Moderate fumarolic activity of the volcano was observed on October 17-22. According to satellite data, the volcano was quiet last week.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895
m
AVIATION COLOR CODE IS YELLOW
Growth of the lava dome continues. Sudden ash emission related
to this activity could affect low-flying aircraft in the vicinity of the
volcano.
Seismicity activity of the volcano didn't exceeded background levels last week. Moderate fumarolic activity of the volcano was noted on October 18-22. Clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly was registering over the lava dome on October 16-22. Clouds obscured the volcano in the other days of week.

KIZIMEN VOLCANO: 55°12'N, 160°32'E; Elevation 2,485 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues. KVERT continues to watch the Kizimen volcano.
Seismic activity of the volcano was above background levels on October 15-19 and didn't exceeded background levels in the others days of week. According to satellite data, a weak thermal anomaly over the volcano was registered on October 16.

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.
