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 was slightly above background levels. Many shallow volcanic earthquakes and weak intermittent volcanic tremor were registered. According to seismic data, weak ash plumes and avalanches occurred at the volcano last week. Strong gas-steam plume, extending to the south, was observed on July 31, clouds obscured the volcano in other days. According to satellite data, a 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, 150-600 shallow volcanic earthquakes and a spasmodic volcanic tremor were registered at volcano all days. According to seismic data, possibly ash explosions rose up to 3.0 km (9,850 ft) ASL . According to satellite data, a thermal anomaly was noted on July 31 and August 02, gas-steam plume extended 23 km (14 mi) to the south-west on August 02, the volcano was obscured by clouds on the other days.

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

Seismic activity was at background levels. But sudden ash explosions up to 6 km (19,700 ft.) ASL could affect international and low-flying aircraft.

Seismic activity was at background levels last week, weak continuous spasmodic volcanic tremor and a few shallow earthquakes were registered. According to video and visual data, gas-steam activity was noted on July 31 and the volcano was obscured by clouds on the other days. According to satellite data, thermal anomaly was noted on July 27-28 and August 01.

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 27-29, 31 and August 01 and at background levels on the other days. Many shallow volcanic earthquakes were registered during the weak. According to satellite data a thermal anomaly was noted on July 28 and August 02, clouds obscured the volcano on 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.
