KLYUCHEVSKOY VOLCANO; 56°03'N, 160°39'E; Elevation 4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE

The explosive-effusive eruption of Klyuchevskoy continues but activity has decreased. Ash explosions up to 8 km (26,250 ft.) ASL are still possible. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of Klyuchevskoy is decreasing generally from June 28, but remained above background levels last week. Many shallow earthquakes were registered. According to video data, ash plumes up to 7.0 km (22,960 ft) ASL on July 09-11. According to satellite data, ash plumes extended for about 20-350 km (or 12-218 mi) to the north-east and north-west from the volcano on July 05-11. Approximate plume altitude: 5000-6500 m (16,000-21,320 ft) ASL (by atmospheric profile). Clouds obscured the volcano in other days.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE

Growth of the lava dome continues. Ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity remains above background levels. Many shallow volcanic earthquakes were registered. According to seismic data, ash plumes up to 6.5 km (20800 ft) ASL occurred at the volcano last week. Gas-steam plumes up to 4.0-5.0 km (13,100-16,400 ft) ASL were observed on July 09-11. Clouds obscured the volcano in other days. According to satellite data, a big thermal anomaly was noted all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE

The eruption of the volcano continues. Ash explosions up to 6 km (or 19,700 ft.) ASL are possible at any time. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano.

Seismic activity was above background levels all week. According to seismic data, possibly ash explosions rose up to 2.5 and 3.8 km (8,200-12,460 ft) ASL on July 07 and 10 respectively. A spasmodic volcanic tremor was registered at volcano all week. According to satellite data, thermal anomaly was noted on July 10-11, volcano was obscured by clouds in other days.

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

Growth of the lava dome continues. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano.

Seismic activity was slightly above background levels on July 05-06 and 08. According to satellite data a thermal anomaly was noted on July 08 and 10-11, clouds obscured the volcano all 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.
