KVERT INFORMATION RELEASE 03-10
Thursday, January 21, 2010, 22:30 UTC (Friday, January 21, 10:30 KST)

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 4.7 km (15,400 ft) ASL last week. According to visual data, strong and moderate fumarolic activity was observing all week. 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, strong and moderate fumarolic activity was observing all week. Strombolian activity of the volcano continues. A height of bursts was about 300 m above the crater. 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. A height of bursts was about from 4.5 till 8.0 km (from 14,760 till 26,200 ft) ASL. 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 ash plumes rose up to 3 km (9,840 ft) ASL last week. According to satellite data, a thermal anomaly was registering over the volcano all 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. Moderate fumarolic activity of the volcano was observed all week. According to satellite data, a thermal anomaly over the lava dome was registering all 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.
