KLYUCHEVSKOY VOLCANO; 56°03'N, 160°39'E; Elevation 4,750
m
CURRENT LEVEL OF CONCERN COLOR CODE IS
ORANGE
Explosive-effusive eruption of the volcano continues. Ash
explosions up to 8 km (26,250 ft.) ASL are possible without warning and could
affect international and low-flying aircraft.
Seismicity remains above background levels. Volcanic earthquakes
and strong volcanic tremor were registered. According to visual and video data,
ash plumes rose up to 7.0 km (23,000 ft) ASL and extended to the east,
south-east and north-west from the volcano on June 08-10 and 13. Strombolian and
Vulcanian activity of the summit crater, lava flows and phreatic bursts at the
south-eastern flank of the volcano were observed on June 08 and 13. Clouds
obscured the volcano on other days. According to satellite data, ash plumes
extended for about 120 km (75 mi) to different directions all week. A large
thermal anomaly persists.
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 6.3 km (20,700 ft) ASL occurred at the volcano last week. Gas-steam plumes up
to 4.0 km (13,100 ft) ASL were observed on June 08-10 and 13, ash plumes rose up
to 4.5 km (14,800 ft) ASL and extended to the south-east and east on June 08-10.
Clouds obscured the volcano on other days. According to satellite data, ash
plumes extended for 45 km (28 mi) to the north-west from the volcano on June 12.
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
An 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 almost all week.
According to seismic data, possibly ash explosions rose up to 6.8 km (~22,300
ft) ASL on June 08-13. According to satellite data, ash plumes extended for 30
km (19 mi) to the south and south-west from the volcano on June 11. A thermal
anomaly was noted again on June 9-10 and 12-13.
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.
Strong seismicity at nearby Klyuchevskoy makes it difficult to
characterize seismicity at Bezymianny. According to visual and video data,
gas-steam plumes rose up to 3.0 km (9,900 ft) ASL and extended to the south-east
on June 08 and 12-13. Clouds obscured the volcano on the other days. According
to satellite data, a thermal anomaly over the lava dome was noted on June 08, 10
and 12.

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.
