KVERT INFORMATION RELEASE 61-10
November 19, 2010, 00:05 UTC (11:05 KST)
KAMCHATKA
Real-time seismic data:
SHEVELUCH and KARYMSKY: ORANGE
KLYUCHEVSKOY, GORELY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, USHKOVSKY, KORYAKSKY,
AVACHINSKY, MUTNOVSKY and KIZIMEN: GREEN
No seismic data: ICHINSKY, VYSOKY, GAMCHEN, KOMAROV, KRONOTSKY, KRASHENINNIKOV, KIKHPINYCH, TAUNSHITS, MALY SEMYACHIK, ZHUPANOVSKY, OPALA, KSUDACH, ZHELTOVSKY, ILIINSKY, KOSHELEV, KAMBALNY, DIKII GREBEN, KHODUTKA and KHANGAR: GREEN
NORTHERN KURILES
No seismic data:
EBEKO, CHIKURACHKI, ALAID, TATARINOV, FUSS PEAK and KARPINSKY: GREEN
SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m (~8,200 ft)
AVIATION COLOR CODE IS ORANGE
Growth of the lava dome and ash emission constrained with this continues. Ash explosions up to 10 km (or 32,800 ft) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Moderate seismic activity of the volcano continues. According to seismic data, possibly, ash plumes rose up to 3.5 km (11,500 ft) ASL all week. According to visual data, strong gas-steam activity of the volcano was observed on November 16-18; clouds obscured the volcano on the other days of week. According to satellite data, two distinct thermal anomalies were registered all week. These anomalies reflect the hot lava dome and the area of recent pyroclastic flow deposits (the eruption was on 27 October, 2010). Ash plumes extending about 100 km (62 mi) to the northern and eastern directions from the volcano and ash clouds up to 60 x 32 km in length and width were noted on satellite images on November 11-14.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m (4,874 ft)
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions up to 6.0 km (or 19,700 ft) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.
Seismicity of the volcano was above background levels all week. Based on seismicity, it is possible that ash plumes rose up to 5.2 km (17,100 ft) ASL on November 13 and 17. According to satellite data, a thermal anomaly was registered over the volcano on November 11-14 and 15-18. Ash clouds, up to 23x10 km in length and width were detected in the distance 82 km and 15 km to the north-east from the volcano on November 16 and 17, respectively.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m (15,580 ft)
CURRENT AVIATION COLOR CODE IS YELLOW
Activity of the volcano is decreasing after the long explosive-effusive eruption (August 2009 - November 2010). Fumarolic activity of the volcano continues. Aerosol plumes could affect low-flying aircraft.
Seismicity of the volcano was above background levels on November 12-14, and didn't exceeded background levels on other days of week. According to visual data, strong fumarolic activity of the volcano was observed on November 16-18. Clouds obscured the volcano on the other days of week. A weak thermal anomaly over the volcanic crater was registered on satellite images all week. An ash plume extended about 40 km to the north-east from the volcano on November 13, and a gas-steam plume about 28 km to the north-east - on November 14.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m (5,996 ft)
AVIATION COLOR CODE IS YELLOW
Seismic and thermal activity of the volcano remains high. This ongoing unrest may eventually lead to an explosive eruption. At present, aerosol plumes from the volcano could affect low-flying aircraft.
Seismicity of the volcano was above background levels all week, volcanic tremor continues to be recorded. According to visual data, weak or moderate gas-steam emissions were observed on November 12-14 and 16-18; clouds obscured the volcano on the other days of week. According to satellite data, a weak thermal anomaly was registered over the volcano on November 12-14 and 18. A gas-steam plume extended about 40 km (25 mi) to the north-east from the volcano on November 12.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m (9,455 ft)
AVIATION COLOR CODE IS YELLOW
Grows of the lava dome of the volcano continues and aerosol plumes could affect low-flying aircraft.
Seismicity of the volcano did not exceed background levels last week. According to visual data, moderate gas-steam emissions were observed on November 16-18. Clouds obscured the volcano on the other days of week. According to satellite data, a weak thermal anomaly was registered over the volcano on November 11-12, 14 and 16-18.

BEGINNING IN NOVEMBER 2010, KVERT WILL ASSIGN AN AVIATION COLOR CODE FOR 22 ADDITIONAL VOLCANOES OF KAMCHATKA AND THE NORTHERN KURILES. THESE VOLCANOES ARE NOT PRESENTLY MONITORED WITH SEISMIC INSTRUMENTS HOWEVER KVERT SCIENTISTS EXAMINED SATELLITE INFORMATION EACH DAY TO LOOK FOR EVIDENCE OF VOLCANIC UNREST SINCE 2002. NOT ALL OF THESE VOLCANOES HAD ERUPTIONS IN HISTORICAL TIME, HOWEVER THEY ARE POTENTIALLY ACTIVE AND THEREFORE ARE OF CONCERN TO AVIATION.

The KVERT Project 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.
