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-effusive 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.
Seismic activity of the volcano was mainly low last week. According to visual data, a viscous lava flow continues to effuse into the explosive crater of 2010 eruption. Moderate fumarolic activity of the lava dome and sometimes weak hot avalanches from the lava flow were observing all week. A thermal anomaly was noting over the lava dome all week at satellite images.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
AVIATION COLOR CODE IS ORANGE
Effusive eruption of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) ASL are possible. Ongoing activity could affect international and low-flying aircraft.
Moderate seismic activity of the volcano continues. Video data and satellite imagery showed that the lava flow continues to effusing on the eastern volcanic flank. Hot avalanches accompany the lava flow effusion. Strong gas-steam activity of the volcano was noting at video camera all week. A big 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 13,500 ft (4.1 km) a.s.l. all week. According to satellite data, an ash cloud 3x7 km in size was noted in 6.2 mi (10 km) to southeast of the volcano on February 06. A thermal anomaly was registering over the volcano all week.

GORELY VOLCANO (1000-07)
52°33'N, 158°02'E; Elevation 5,996 ft (1,828 m)
AVIATION COLOR CODE IS YELLOW
Seismic activity of the volcano remains some heightened. Ash explosions up to 19,700 ft (6 km) ASL are possible. Ash and aerosol plumes from the volcano could affect low-flying aircraft.
Seismic activity of the volcano remains some heightened on February 02-04; there was not seismic data from February 05 by technical reasons. According to visual data, a strong and moderate gas-steam activity of the volcano was observed all week. A thermal anomaly was registering over the volcano on February 04-05 and 07 at satellite images.

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 are possible. Ash and aerosol plumes could affect low-flying aircraft.
Seismic activity was mainly low last week. According to visual data, a strong and moderate gas-steam activity of the volcano was observed all week. According to satellite data, a thermal anomaly over the volcano was noted on the satellite images all week.

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 was available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week in 2005-2011. Now KVERT scientists is available in the office from 8:30 AM till 6:00 PM (KST) in the work days and by phone during the evenings. KVERT uses daily satellite imagery, information from remote scientific observation stations, real-time seismic data for 11 Kamchatkan volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
