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:
EBEKO, CHIKURACHKI and ALAID: GREEN

CURRENT CHANGES IN AVIATION COLOR CODE:
AVIATION COLOR CODE OF GORELY: YELLOW


GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE WAS GREEN

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 the average about 1.6 mkm/s all week. Strong and moderate gas-steam activity of the volcano was observing on June 17-22. According by volcanologists who worked at the volcano last week, a new vent on the wall of Gorely active crater was discovered on June 17. Magmatic gas with temperature of 800-900 degrees of Celsius is emitting with strong rate from this vent. A red incandesce is noting into this vent. According to satellite data, the thermal anomaly over the volcano was registering on June 17-18 and 21-23. Clouds obscured the volcano in the other days.

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 activity of the volcano were observing on June 19, 21 and 23. Sometimes ash columns rose up to 5.5 km (18,040 ft) ASL. Clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending about 120 km (74 mi) to the different directions from the volcano were noted on June 19 and 22-23.

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. According to seismic data, possibly ash plumes rose up to 5.1 km (16,700 ft) ASL all week. According to visual data, ash plume rose up to 6.5 km (21,300 ft) ASL on June 23, strong fumarolic activity and hot avalanches were observed on June 21-23. Clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the lava dome all week. An ash cloud in size 5x5 km was noted in 30 km (18.6 mi) to the south-east from the volcano on June 23.

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 June 17, and there were not all data in the other days of week by technical reasons. According to seismic data, possibly ash plumes rose up to 6.4 km (21,000 ft) ASL all week. According to satellite data, a thermal anomaly was registering over the volcano on June 17, 19-20 and 22-23. Ash clouds in sizes 10x8 km and 12x5.5 km were noted in the eastern sector of the volcano on June 17 and 23, respectively. Clouds obscured the volcano in the other days.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW

Activity 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, clouds obscured the volcano all week. According to satellite data, a small thermal anomaly was registering over the dome on June 19 and 21-23.

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.
