CURRENT CHANGES IN AVIATION COLOR CODE
KORYAKSKY IS NOW AT AVIATION COLOR CODE: GREEN
KORYAKSKY VOLCANO; 53°19'N, 158°43'E; Elevation 3,456
m
CURRENT AVIATION COLOR CODE IS GREEN
PREVIOUS AVIATION COLOR CODE WAS YELLOW
Fumarolic activity of the volcano continues and such activity is normal for the volcano. Last time there were ash plumes at the volcano on August 13-27. But strong gas-steam plumes could affect low-flying aircraft.
Seismicity didn't exceeded background levels all week. Moderate fumarolic activity of the volcano was observing on October 29 and November 04-05. Clouds obscured the volcano in the other days of week. According to satellite data, the volcano was quiet last week.

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 4.7 km (15,400 ft) ASL all week. According to infrared video data, ash plumes rose up to 8 km (26,400 ft) ASL on October 30. Moderate fumarolic activity of the volcano was observing last week. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plumes extending about 255 km (158 mi), 150 km (94 mi) and 130 km (81 mi) to the E from the volcano was noted on October 30 and November 01 and 05, respectively.

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 continues. A height of bursts was about 300 m above the crater. Moderate fumarolic activity of the volcano was noted on October 30 and November 01-04, clouds obscured the volcano in the other days of week. According to satellite data, a big 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 on October 29-31. There was no seismic data by technical reasons on November 01-04. According to seismic data, possibly ash plumes rose up to 3.7 km (12,100 ft) ASL on October 31 and November 05. According to satellite data, a thermal anomaly was registering over the volcano on October 29 and November 01-04. Ash plumes extending about 180 km to the eastern directions from the volcano were noted on October 29-30 and November 01, 03 and 05.

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.
Seismic activity of the volcano didn't exceeded background levels last week. Moderate fumarolic activity of the volcano was noted on October 29-30 and November 01-05. Clouds obscured the volcano on October 31. According to satellite data, a weak thermal anomaly was registering over the lava dome on November 01 and 03-04. 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 slightly above background levels on October 29-30 and November 01, and didn't exceeded background levels in the others days of week. According to satellite data, the volcano was quiet or obscured by clouds last 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.
