KVERT INFORMATION RELEASE 15-10
Thursday, April 01, 2010, 22:55 UTC (Friday, April 02, 10:55 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


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 sometimes containing small amount of ash rose up to 5.3 km (17,400 ft) ASL all week. Strombolian activity of the volcano continues. A height of bursts was about 300 m above the crater. An effusion of lava flows on the volcanic flanks continues. According to satellite data, a big thermal anomaly was registering over the volcano all week. Gas-steam plumes extending about 70 km (43 mi) to the east from the volcano were noted on March 30.

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 all week. According to visual data, strong fumarolic activity was noted last week. Hot avalanches from the lava dome were observing in the dark time. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plume extending about 40 km (25 mi) to the south-east from the dome was noted on March 29.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
AVIATION COLOR CODE IS ORANGE


Activity of the volcano continues. Ash explosions > 6.0 km (or 19,700 ft) ASL could occur at any time. 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, ash plumes rose up to 4.1 km (13,500 ft) ASL all week. According to satellite data, a bright thermal anomaly was registering over the volcano all week. Ash plumes extending about 250 km (155 mi) to the eastern directions from the volcano were noted on March 28-29 and 31.

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. Strong (March 29) and moderate fumarolic activity of the volcano was observed on March 26-30, clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly over the lava dome was registering on March 26-31 and April 01.

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.
