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

CURRENT CHANGES IN AVIATION COLOR CODE:
AVIATION COLOR CODE OF EBEKO: GREEN

EBEKO VOLCANO: 50°41'N, 156°01'E Elevation 1,156 m
CURRENT AVIATION COLOR CODE IS GREEN
PREVIOUS AVIATION COLOR CODE WAS YELLOW


A weak 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 quiet all week. KVERT continues to monitor the volcano.

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 all week. Sometimes ash columns rose up to 6.3 km (20,700 ft) ASL. Lava flow continues to effusing at the south-south-western 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 120 km (74 mi) to the south-west from the volcano on July 16-19, about 54 km (33 mi) to the south-east on July 20, and about 160 km (99 mi) to the north-east on July 21-22.

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 weak ash bursts occurred at the lava dome. According to visual data, ash plumes rose up to 5.5 km (18, 040 ft) ASL on July 20-21. Gas-steam plumes rose up to 3.7 km (12,100 ft) ASL all week. According to satellite data, a thermal anomaly was registering over the lava dome all week. Ash plumes extended about 50 km (31 mi) to the north-east from the volcano on July 21.

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 all week. According to seismic data, possibly ash plumes rose up to 3.0 km (10,000 ft) ASL. According to satellite data, a thermal anomaly was registering over the volcano all week. Ash plumes extended about 58 km (18,6 mi) to the south-west from the volcano on July 19, and about 85 km (53 mi) to the south-east on July 21.

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 all week. According to the data by KVERT-staff on July 20, a strong magmatic gas emission continues. Lake level into Active crater fell yet. Many new small fumarolic vents were noted into Active crater. According to satellite data, a thermal anomaly over the volcano was registering all week. Temperature of anomaly gradually increased from 29 till 46 degrees of Celsius from July 17 till July 21.

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 all week. According to satellite data, a small thermal anomaly was registering over the dome on July 17-21, 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.
