SUMMARY OF AVIATION COLOR CODES:
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
GORELY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY and KIZIMEN: GREEN
NORTHERN KURILES:

CHIKURACHKI and ALAID: GREEN
KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
AVIATION COLOR CODE IS ORANGE
Explosive-effusive eruption of the volcano continues. Ash explosions >7.0 km (>23,000 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Seismicity of the volcano was above background levels all week. According to visual data, Strombolian and moderate gas-steam with ash activity of the volcano were observing on July 09, 12 and 14-15. Sometimes ash columns rose up to 6.8 km (22,300 ft) ASL. Clouds obscured the volcano on July 13. According to satellite data, a big thermal anomaly was registering over the volcano all week. A gas-steam plume containing small amount of ash extended about 45 km (28 mi) to the north-west from the volcano on July 14.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive eruption of the volcano continues. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Seismicity was above background levels all week - possibly ash plumes rose up to 4.3 km (14,100 ft) ASL. According to visual data, gas-steam plumes rose up to 3.7 km (12,100 ft) ASL on July 09 and 11-14. Clouds obscured the volcano in the other days. According to satellite data, a thermal anomaly was registering over the lava dome all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions > 6.0 km
(> 19,700 ft) ASL could occur at any time. Aactivity of the volcano
could affect low-flying aircraft.
Seismic activity of the volcano was above background levels on July 12-14. There was not seismic data in the other days of week by technical reasons. According to seismic data, possibly ash plumes rose up to 3.3 km (10,800 ft) ASL on July 12-14. According to satellite data, a thermal anomaly was registering over the volcano on July 08-10 and 12. Clouds obscured the volcano in the other days of week. Ash plumes extended about 30 km (18,6 mi) to the west and south from the volcano on July 07-08.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano is increasing. Probably an eruption of Gorely is preparing. Aerosol plumes from the volcano could affect low-flying aircraft.
Seismicity of the volcano was above background levels all week, Amplitude of volcanic tremor was about 1.8 mkm/s. Strong and moderate gas-steam activity of the volcano was observing on July 09-12. Clouds obscured the volcano in the other days. According to the data by KVERT-staff on July 10, a size of new fumarolic vent with magmatic gas was increasing in 2-3 times. Lake level into Active crater fell. According to satellite data, a small thermal anomaly over the volcano was registering on July 08, 10, 12 and 14. A gas-steam plume extended about 25-150 km to the south-east, east and south from the volcano on July 10 and 14-15.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW
Grows of the lava dome of the volcano continues and aerosol plumes could affect low-flying aircraft.
Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny all week. According to visual data, moderate gas-steam activity of the volcano was observing on July 09-10, clouds obscured the volcano in the other days. According to satellite data, a small thermal anomaly was registering over the dome on July 08-10, clouds obscured the volcano in the other days.

EBEKO VOLCANO: 50°41'N, 156°01'E Elevation 1,156 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues. Ebeko volcano is not monitored with seismic instruments. KVERT has satellite monitoring and occasional visual messages about this volcano. The danger of sudden ash explosions as high as 3 km (9,840 ft.) ASL as well as ash falls at Severo-Kurilsk, exists.
According to visual and satellite data, the volcano was obscured by clouds all week. KVERT continues to monitor the volcano.

The Kamchatkan Volcanic Eruption Response Team (KVERT) 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).
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 10 volcanoes, and other information to
monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
