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 14,800 ft (4.5 km) ASL on July 04 and 06. According to visual data, moderate gas-steam activity of the volcano was observing on July 04; clouds obscured the volcano on the other days of week. According to satellite data, a gas-steam plume containing ash was extending about 48 mi (78 km) to the north-east from the volcano on July 04-05; a thermal anomaly was registered over the lava dome on July 02-05; clouds obscured the volcano on the other days.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
CURRENT AVIATION COLOR CODE IS ORANGE
Eruption of the volcano continues. 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.
Seismic activity was above background levels all week. Weak volcanic tremor continues to registering all week. According to visual data from Tolbachik volcano slope, a strong fumalolic activity of Kizimen was observing on June 25-27. Some deformation of Kizimen edifice was noted on June 25-27. A bright thermal anomaly was registering over the volcano on July 02-05 at satellite images; on the other days it was obscured by clouds.
*****
History of Kizimen eruptions is unknown. We have incomplete data about
only one eruption in 1928-1929 which were likely moderate explosive (or
explosive-effusive) events. Tephrachronological data point out several
catastrophic eruptions in evolution of this volcano.

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, possible ash plumes rose up to 13,120 ft (4.0 km) ASL all week. A thermal anomaly was registering over the volcano on July 02 and 04-05. Ash plumes extending about 8.7 and 23.6 mi (14 and 38 km) to the north-west and north were noted at satellite images on July 02 and 05, respectively.

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 does not exceed background levels all week. According to video data, the volcano was obscured by clouds all week. According to satellite data, a thermal anomaly over the lava dome was registering on July 02.

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 weak volcanic tremor was registering at the volcano all week. According to video data, the volcano was quiet or obscured by clouds this week. A thermal anomaly over the volcano was registering on July 02 and 05. Clouds obscured the volcano on the other days.

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) since 1993. 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 11 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
