KAMCHATKA
Real-time seismic data:
SHEVELUCH, KIZIMEN and KARYMSKY: ORANGE
BEZYMIANNY and GORELY: YELLOW
KLYUCHEVSKOY, TOLBACHIK PLOSKY, USHKOVSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY: GREEN

NORTHERN KURILES

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.

SHEVELUCH VOLCANO (1000-27)
56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~8,200 ft (~2,500 m)
AVIATION COLOR CODE IS
ORANGE

Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) 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, probably ash plumes rose up to 26,200-34,400 ft (8.0-10.5 km) on October 13-18. All three seismic stations do not work by technical reasons from October 19 till present. According to visual data, hot avalanches were observing at the lava dome on October 13-16 and 20. Ash plumes from hot avalanches rose up to 19,700 ft (6.0 km) ASL on these days; strong fumarole activity was observing too. Ash plumes extending about 46.5 mi (75 km) to the eastern directions from the volcano were noted on October 14 and 16, at the satellite images. A big thermal anomaly was noting over the lava dome all week.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
CURRENT AVIATION COLOR CODE IS
ORANGE

Activity of the volcano is gradually decreasing but strong ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Probably the eruption of the volcano gradually go to finish. Moderate seismic activity of the volcano was registering last week: numbers of volcanic earthquakes were changing from 22 to 60; a magnitude of volcanic tremor was mainly 0.3-0.5 mcm/s. According to video data, a result of ashfalls were noted on October 14-15: an ash covered snow at all volcanic flanks. Probably power gas-steam plumes contained ashes on October 14. A large lava flow continues to effuse on the north-eastern volcanic slope; strong fumarole activity was observing on October 13-16. A thermal anomaly was registering over the volcano all week at satellite images.

KARYMSKY VOLCANO (1000-13)
54°03'N, 159°27'E; Elevation 4,874 ft (1,486 m)
AVIATION COLOR CODE IS ORANGE


Explosive activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.

Moderate seismic activity of the volcano continues; according to seismic data, possible ash plumes rose up to 10,800 ft (3.3 km) ASL on October 13-15, and less on the other days of week. According to satellite data, a thermal anomaly was registering over the volcano on October 14 and 16.

BEZYMIANNY VOLCANO (1000-25)
55°58'N, 160°36'E; Elevation 9,455 ft (2,882 m)
AVIATION COLOR CODE IS YELLOW


Effusion of viscous lava flow at the dome slope continues. Small ash plumes from hot avalanches is possible. Ash and aerosol plumes could affect low-flying aircraft.

Seismic activity was mainly low last week. One volcanic earthquake with magnitude 1.35 was registered in the area of the volcano on October 16. Moderate fumarolic activity of the volcano was observing on October 13, 15 and 16; clouds obscured the volcano on the other days. Thermal anomaly over the volcano was noted on the satellite images on October 15-16 and 18-19.

GORELY VOLCANO (1000-07)
52°33'N, 158°02'E; Elevation 5,996 ft (1,828 m)
AVIATION COLOR CODE IS YELLOW


Seismic and thermal activity of the volcano remains high. This ongoing unrest may eventually lead to an explosive eruption. Aerosol plumes from the volcano could affect low-flying aircraft.

Moderate seismic activity of the volcano continues and a volcanic tremor was registering at the volcano all week. According to visual data, the volcano was quiet or obscured by clouds all week. A weak thermal anomaly over the volcano was noted at satellite images on October 15 and 18.

The KVERT Project is a cooperative program of the Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS since 1993. KVERT scientists is available in the office from 8:30 AM till 6:00 PM (KST) and by phone during the evenings. KVERT uses daily satellite imagery, information from remote scientific observation stations, real-time seismic data for 11 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
