KARPINSKY: GREEN
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 13,120 ft (4.0 km) ASL on July 14-15 and 20. According to visual data, ash explosions rose up to 16,400 ft (5.0 km) ASL on July 14; moderate fumarole activity was observing on July 19-20; clouds obscured the volcano on the other days of week. According to satellite data, an ash plume extended about 8 mi (13 km) to the south-west from the volcano on July 15; a thermal anomaly was registering over the lava dome on July 14-15 and 18-19; 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 seismic data, possible ash plumes rose up to 11,480 ft (3.5 km) ASL on July 19-20. According to visual data by seismologists from the area of the volcano, gas-steam plumes containing ash rose up to 9,840 ft (3.0 km) ASL and extended about 9 mi (15 km) to the east from the volcano on July 20. A lava flow continues to moving at the eastern flank of the volcano. A bright thermal anomaly was registering over the volcano all week at satellite images. A powerful gas-steam plume was extending about 32 mi (52 km) to the north-west from the volcano on July 19.
*****
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 14, 16 and 18-21; the volcano was obscured by clouds on the other days of week.

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 visual data by volcanologists, a moderate fumarole activity was observing on July 19-20, the volcano was obscured by clouds on the other days of week. According to satellite data, a thermal anomaly was registering over the volcano on July 14 and 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 weak volcanic tremor was registering at the volcano all week. According to visual data, a moderate fumarole activity was observing on July 20, the volcano was obscured by clouds on the other days of week. A thermal anomaly was registering over the volcano on July 14.

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.
