KVERT has reached a temporary funding agreement and the KVERT Project has returned to full operations. KVERT will provide daily analysis and evaluation of activity of volcanoes of Kamchatka and Northern Kuriles to ensure safe air services. The temporary agreement will fund the KVERT Project until 30 April 2010.

Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 05-10

SUMMARY OF AVIATION COLOR CODES:

KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, GORELY, MUTNOVSKY and KIZIMEN: 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 5.7 km (18,700 ft) ASL last week. According to visual data, moderate fumarolic activity of the volcano was observing on February 01, clouds obscured the volcano in the other days. 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

Explosive-effusive eruption of the volcano continues. Ash explosions > 7.0 km (>23,000 ft)ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismicity of the volcano was above background levels all week. According to visual data, gas-steam plumes rose up to 6.2 km (20,300 ft) ASL on January 30-31. Strombolian activity of the volcano continues. A height of bursts was about 300 m above the crater. Clouds obscured the volcano in the other days. An effusion of a lava flow on the north-western volcanic flank (Krestovsky chute), continues. Phreatic bursts sometimes were observed at a front of this lava flow. 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 all week. According to seismic data, possibly weak ash-gas bursts occurred last week. According to satellite data, a thermal anomaly was registering over the volcano on January 28 and February 01. Clouds obscured the volcano in the other days of week.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW

Activity of the volcano continues and its aerosolic plumes could affect low-flying aircraft.

Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny last week. Weak and moderate fumarolic activity of the volcano was observed on January 31. Clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly over the lava dome was registering on January 29-30 and February 02.

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.
