KVERT IVS FED RAS monitor 30 active volcanoes of Kamchatka and 6 active volcanoes of Northern Kuriles.

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 (IVS FED RAS) 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.

Explosive activity of the volcano continues: visual observation shows ash plumes rose up to 13,100 ft (4.0 km) a.s.l. on March 30 and April 03. According to seismic data, possibly ash plumes rose up to 21,600 ft (6.6 km) a.s.l. each day during last week. Visual and satellite data show, a viscous lava flow continues to effuse into the explosive crater of 2010 eruption, strong and moderate fumarolic activity accompany the lava flow effusion. According to satellite data, ash plumes extended for about 71 mi (114 km) to the west, east and northeast of the volcano on March 29-30 and April 03; a weak thermal anomaly was noting over the lava dome on March 29-31 and April 03.

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 8,200 ft (2,5 km) a.s.l. all week. According to satellite data, a thermal anomaly was registering over the volcano on March 29.

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

Effusive eruption of the volcano continues: the large lava flow effuses on the eastern volcanic flank. Strong gas-steam volcanic activity and moderate hot avalanches accompanies this process. Aerosolic plumes, and small ash plumes from hot avalanches, could affect 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 and strong gas-steam activity accompany the lava flow effusion. A thermal anomaly over the volcano was noting on March 29-31 and March 03 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

Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

Seismic activity was low last week. A viscous lava flow continues to effuse on the southern lava dome slope - strong and moderate gas-steam activity of the volcano accompanies this process. According to satellite data, a thermal anomaly was registering over the volcano on March 29-31 and April 03-04; clouds obscured the volcano in the other days of week.

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


Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

There was not seismic data from February 05 till present by technical reasons. Moderate gas-steam activity of the volcano was observing on March 29-30 and April 04; clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly was registering over the on March 29.

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 (IVS FED RAS) analyses daily satellite imagery; information from remote scientific observation stations; real-time seismic data for 11 Kamchatkan volcanoes (data from KBGS RAS); and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
