KARYMSKY VOLCANO: 54œ03'N, 159œ27'E;
Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
Seismic data and satellite observations
indicated that the eruption of the volcano with ash explosions from the summit
crater continues. Ash explosions up to 6 km (or 19,700 ft.) ASL are possible.
The activity of the volcano could affect low-flying aircraft in the vicinity of
the volcano.
Eruptive activity at the volcano continues.
According to seismic data, ash plumes rose up to 3.5 km (11,500 ft) ASL this
week. A number of local shallow earthquakes was from 100 till 350 per day.
Spasmodic volcanic tremor was registering all days. According to the pilots
reports, ash plumes of the volcano rising up to 2.0 km (6,500 ft.) ASL and
extending to the north-east on June 28. A thermal anomaly over the volcanic
crater was observed on June 24-27.
BEZYMIANNY VOLCANO: 55œ58'N,
160œ36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
According to volcanologists’ experience, growth of the lava dome continues.
Lava effusion is probably occurring at the lava dome. The activity of the
volcano could affect low-flying aircraft in the vicinity of the volcano.
There was no seismic information on this week. A big thermal anomaly was
noted at the volcano on June 24 and 29. Clouds obscured the volcano all
week.
SHEVELUCH VOLCANO: 56œ38'N, 161œ19'E; Elevation 3,283 m, the dome
elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Growth of the lava dome continues. A fumarolic activity of the lava dome
was observed on June 23 and 29. A thermal anomaly over the dome was noted on
June 23-24. Seismic activity was at background levels last week but ash
explosions up to 6 km (19,700 ft.) ASL could occur at any time.

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 Kurile Volcanoes.
