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 activity of the volcano continues. Moderate gas-steam activity with small amount of ash was observing all week. Ash columns rose up to 7.25 km (23,780 ft) ASL on June 05. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending about 60-190 km (35-120 mi) to the north-east from the volcano were noted on June 05 and 08.

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 4.1 km (13,400 ft) ASL on June 03-04 and 06. According to visual data, ash plumes rose up to 4.5 km (14,800 ft) ASL on June 04-06 and 09, strong fumarolic activity was observed all week. Hot avalanches were noting in the dark time. According to satellite data, a big thermal anomaly was registering over the lava dome all week. Ash plumes extended about 100 km (62 mi) to the south-east from the volcano on June 04.

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 2.5 km (8,200 ft) ASL on June 06. According to satellite data, a thermal anomaly was registering over the volcano on June 04-05 and 08.

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. Clouds obscured the volcano all week. According to satellite data, a thermal anomaly was registered on June 04-05 and 08.

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.
