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, EBEKO 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 23-24 and 29. Clouds obscured the volcano in the other days of week. Lava flow continues to effusing at the south-south-eastern flank of the volcano. According to satellite data, a big thermal anomaly was registering over the volcano all week. A gas-steam plume containing some amount of ash extended about 145 km (90 mi) to the south-west from the volcano on July 28.

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 from explosions rose up to 6.5 km (21,300 ft) ASL on July 27-28, and from hot avalanches - about 4-5 km (13,100-16,400 ft) ASL. According to visual data, gas-steam plumes rose up to 4 km (13,100 ft) ASL on July 23-24. Clouds obscured the volcano in the other days of week. 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 23-24 and 28. There was not seismic data in the other days of week by technical reasons. According to seismic data, possibly ash plumes rose up to 2.0 km (6,600 ft) ASL. According to satellite data, a thermal anomaly was registering over the volcano all week. Ash plumes extended about 15 km (9 mi) to the south-east on July 26.

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, volcanic tremor continues to registering. Moderate gas-steam activity of the volcano was noting on July 26-27. Clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly over the volcano was registering all week.

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 23-24 and 29. Clouds obscured the volcano in the other days of week. According to satellite data, a small thermal anomaly was registering over the dome on July 25 and 27-28, clouds obscured the volcano in the other days.

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.
