SUMMARY OF AVIATION COLOR CODES:

KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, GORELY, MUTNOVSKY and KIZIMEN: GREEN

NORTHERN KURILES:
EBEKO, CHIKURACHKI and ALAID: GREEN

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

KVERT-staff note a small increase of size and temperature of the thermal anomaly over the volcano from June 15. Strong gas-steam activity of the volcano was observing on June 06 and 12-13.

Seismicity of the volcano was above background levels all week. Amplitude of volcanic tremor was increasing from 0.5 mkm/s on June 05 till 1.7 mkm/s on June 14, and remains on this levels.

KVERT-staff continue to monitor Gorely 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 activity of the volcano continues. Sometimes ash columns rose up to 5.5 km (18,040 ft) ASL on June 13-16. Ash fall was noted in Klyuchi village on June 11. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending about 40 km (25 mi) to the south-east from the volcano were noted on June 13 and 15.

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. According to seismic data, possibly ash plumes rose up to 4.9 km (16,100 ft) ASL all week. According to visual data, strong fumarolic activity and hot avalanches were observed on June 13-17. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Small thermal anomaly was noted on June 15, near the lava dome - probably over deposits of big hot avalanches.

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 5.2 km (17,060 ft) ASL on June 10-12 and up to 3.9 km (12,800 ft) ASL on June 16. According to satellite data, a thermal anomaly was registering over the volcano on June 11 and 15-16. Ash plumes extending about 196 km (121.5 mi) to the east from the volcano were noted on June 10-11. Small ash cloud was noted in 22 km (13.6 mi) to the east from the volcano on June 17. 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.

Seismic activity of the volcano was above background levels on June 12 and strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny in the other days. According to visual data, moderate gas-steam activity of the volcano was noted on June 13-16. Clouds obscured the volcano in the other days of week. According to satellite data, a thermal anomaly was registered on June 12-17.

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.
