Thursday, October 01, 2009, 21:55 UTC (Friday, October 02, 10:55 KDT)

SUMMARY OF AVIATION COLOR CODES:

KAMCHATKA:
SHEVELUCH and KARYMSKY: ORANGE
KLYUCHEVSKOY, KORYAKSKY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KIZIMEN, 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 7.0 km (23,000 ft) ASL on September 27, and up to 4.5 km (14,800 ft) ASL in the other days of last week. According to visual and video data, ash plumes rose up to 4 km (13,100 ft) ASL on September 28. Moderate fumarolic activity of the volcano was noted on September 28-29. 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. An ash plume extending about 65 km (40 mi) to the east-southeast from the volcano was noted on September 29.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
CURRENT 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 data by volcanologists who flew around of the volcano on October 01, there was noted a one big crater on the top of the volcano. Moderate fumarolic activity of the volcano was observing in the that day. According to seismic data, probably weak ash explosion occurred at the volcano. According to satellite data, a weak thermal anomaly was registering over the volcano on September 28. Clouds obscured the volcano all week.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750  m
CURRENT AVIATION COLOR CODE IS YELLOW

Activity of the volcano continues. Explosive activity with ash of the volcano could affect international and low-flying aircraft.

Seismicity was slightly above background levels all week. Weak volcanic tremor was registering all week. According to visual data, weak Strombolian activity of the volcano was observed on September 28-30. A height of bursts was about 70-100 m above the crater. Moderate fumarolic activity of the volcano was noted in these days, clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly was registering over the volcano all week.

KORYAKSKY VOLCANO; 53°19'N, 158°43'E; Elevation 3,456 m
CURRENT 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 sometimes with weak emissions of ash was observed on September 28-30 and October 01. According to satellite data, the volcano was quiet.

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 didn't exceeded background levels all week. Moderate fumarolic activity of the volcano was noted on September 28. 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 September 28.

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.
