Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 74-09
Thursday, December 24, 2009, 22:35 UTC (Friday, December 25, 10:35 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 4.1 km (13,500 ft) ASL last week. According to video data, a small ash plume occurred at the volcano on December 22; moderate fumarolic activity was observing on December 18 and 21-22, 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.

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 on December 18 and 21-23, 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 east-south-eastern volcanic flank continues too. Clouds obscured the volcano in the other days of week. 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.

There was no seismic data by technical reasons all week. According to satellite data, a thermal anomaly was registering over the volcano all week. Three streaks of ash deposits about 10 km (6 mi) to the south-east from the volcano was noted on the satellite image on December 24.

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.

Seismic activity of the volcano was above background levels on December 22-24. Strong fumarolic activity of the volcano was observing in these days. Gas-steam plumes rose up to 4.0 km (13, 120 ft) ASL. According to satellite data, a big and bright thermal anomaly was registering on December 21-23.

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.
