Scientists of KVERT Project return to the full KVERT operations (the information ensuring of air services for the results of daily analysis and evaluation of activity of Kamchatka and Northern Kuriles volcanoes) and will discharge these obligations for 01 February - 30 April 2010

Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 07-10
Thursday, February 11, 2010, 23:00 UTC (Friday, February 12, 11:00 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


CURRENT CHANGES IN AVIATION COLOR CODE
BEZYMIANNY IS NOW AT AVIATION COLOR CODE: YELLOW


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

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

Possibly a moderate explosive event at Bezymianny volcano occurred in interval from 23:42 UTC on February 05 till 01:58 UTC on February 06, because there is observing a new hot portion of lava flow at the lava dome at now.

Strong volcanic activity of Klyuchevskoy volcano obscures seismic data of Bezymianny last week. Moderate fumarolic activity of the volcano was observed on February 07 and 09. Clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly over the lava dome was registering 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 6.0 km (19,700 ft) ASL on February 08-10. 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 two lava flows on the north-western volcanic flank (Krestovsky chute and some to south), continues. According to satellite data, a big thermal anomaly was registering over the volcano all week. Gas-steam plumes extended about 65 km (40.3 mi) to the north-east from the volcano on February 09-10.

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 5.2 km (17,060 ft) ASL last week. According to visual data, moderate fumarolic activity of the volcano was observing on February 08-10, clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the lava dome 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 weak thermal anomaly was registering over the volcano on February 08. Clouds obscured the volcano in the other days of 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.
