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, CHIKURACHKI and ALAID: GREEN

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 3.7 km (12,100 ft) ASL last week, and up to 6.9 km (22,600 ft) ASL on October 29. According to visual and video data, Moderate fumarolic activity was observing on October 22-24 and 26. Clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly was registering over the lava dome on October 22-27. Clouds obscured the volcano on October 28-29. Ash plume extending about 24 km to the NE from the volcano was noted on October 26.

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. A magnitude of volcanic tremor abrupt increase from October 26. According to visual data, Strombolian activity of the volcano continues. A height of bursts was about 200 m above the crater. Moderate fumarolic activity of the volcano was noted on October 22-27, 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 on October 23-27. There was no seismic data by technical reasons on October 22 and 28. According to seismic data, possibly ash plumes rose up to 3.7 km (12,100 ft) ASL last week. According to satellite data, a thermal anomaly was registering over the volcano on October 23-26 and 29. Ash plumes extending about 120 km to the east from the volcano were noted on October 23. The volcano was quiet or obscured by clouds in the other days of 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, weak volcanic tremor was registering in the area of the volcano on October 24-27. Moderate fumarolic activity of the volcano was observing on October 23-25 and 28-29. Clouds obscured the volcano on October 26-27. 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.

Seismic activity of the volcano didn't exceeded background levels last week. Moderate fumarolic activity of the volcano was noted on October 23-24 and 26. 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 23 and 26. Clouds obscured the volcano in the other days of 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.
