Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 62-07
Thursday, December 13, 2007, 22:50 UTC (Friday, December 14, 10:50 KST)

SUMMARY OF LEVEL OF CONCERN COLOR CODES:
 
KAMCHATKA:
SHEVELUCH: ORANGE
KARYMSKY and BEZYMIANNY : YELLOW 
KLYUCHEVSKOY, TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY, 
KORYAKSKY, MUTNOVSKY and GORELY: GREEN 
 
NORTHERN KURILES:
CHIKURACHKI, EBEKO and ALAID: GREEN
 
SHEVELUCH VOLCANO: 56°38'N, 161°19'E; 
Elevation 3,283 m, the dome elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
 
Growth of the lava dome continues. Ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. 
The activity of the volcano could affect international and low-flying aircraft.
 
Seismic activity was above background levels last week. Many shallow volcanic earthquakes and an intermittent volcanic 
tremor were registered all week. According to seismic data, ash plumes up to 5 km (16,000 ft) ASL occurred at the volcano 
on December 07-09. According to visual and video data, ash plume rose up to 5 km (16,000 ft) ASL on December 12. 
Strong gas-steam plumes up to 4.0-5.0 km (12,800-16,400 ft) ASL were registered all weak. According to satellite data, a 
big thermal anomaly was noting all week.
 
KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m. 
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
 
According to seismic and satellite data, an ash activity of the volcano was not registered last six weeks. However, activity 
of Karymsky can resume at any time and ash explosions up to 6 km (or 19,700 ft.) ASL could occur. The explosive activity 
of the volcano could affect low-flying aircraft in the vicinity of the volcano.
 
Seismic activity was slightly above background levels all week. Weak local shallow earthquakes occurred at the area of the
volcano. According to overflight on December 13, there were not fresh ash deposits on the snow, a weak gas-steam activity 
of the volcano was observed. According to satellite data, a thermal anomaly and ash plumes were not noted.
 
BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
 
Growth of the volcano continues. A viscous lava flow is effusing from the summit lava dome. Sudden ash emission related to 
this activity could affect low-flying aircraft in the vicinity of the volcano.
 
Seismicity of the volcano was above  background levels on December 10-11 and at background levels on December 08-09 
and 12. According to visual and video data, a moderate fumarolic activity was observed at the lava dome all week. According 
to satellite data, a weak thermal anomaly over the dome was observing 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.
