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 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 on October 12-14. Deposits of a small pyroclastic flow was noting on the S-E-flank of the volcano. Fumarolic plumes containing small amount of ash rose up to 3.5 km (13,100 ft) ASL on October 11-13. 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 08-13 and 15. Dense clouds obscured the volcano in the other days of 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 was above background levels all week but a magnitude of a weak volcanic tremor decreased to the end of week. According to visual data, Strombolian activity of the volcano was observed on October 11. A height of bursts was about 200 m above the crater. Fumarolic column containing small amount of ash rose up to 5.7 km (19,700 ft) ASL on October 11. Moderate fumarolic activity of the volcano was noted on October 8 and 11-13, 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 3.7 km (12,100 ft) ASL last week. According to the data by volcanologists who work now at the volcano, ash plume raising up to 3.5 km (11,500 ft) ASL was observed at ~ 23:40 UTC on October 11. 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 08-12 and 14-15. 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 was above background levels on October 12 and didn't exceeded background levels in the others days of week. Moderate fumarolic activity of the volcano was noted on October 12-13. 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 09. 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 08-11 and didn't exceeded background levels in the others days of week. Many shallow earthquakes were registered during October 09-11. According to satellite data, a weak thermal anomaly over the volcano was registered on October 09.

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.
