Strong explosive-effusive eruption of the volcano continues. Ash
explosions up to 10 km (33,000 ft.) ASL could occur at any time and could
affect international and low-flying aircraft.
Seismicity was above
background levels: volcanic earthquakes and a strong volcanic tremor were
registered. According to visual and video data, ash plumes rose up to 5.0
km (16,400 ft) ASL and extended to the north-east from the volcano on June
15, clouds obscured the volcano on other days. Ash falls was noted in Kluchi on
June 17-18 and at Kozyrevsk on June 19-20. Sounds of strong explosions
were heard in Klyuchi on June 14-17. According to satellite data, a large
thermal anomaly persists. Ash plumes extended for about 400 km (249 mi) to the
northern, western and southern directions all week. According to cyclonic
activity at the area of Kamchatka, large ash clouds from Klyuchevskoy, 300x300
km in size, was observed near Yelizovo airoport on June 20-21. Approximate
plumes altitudes based on atmospheric profiles were 6500-9500 m
(21,300-31,200ft) ASL. Ash clouds moved over Yelizovo and
Petropavlovsk-Kamchatsky to the south-east.
SHEVELUCH
VOLCANO: 56œ38'N, 161œ19'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 5.3 km
(17,400 ft) ASL occurred at the volcano last week. Gas-steam plumes
extending to the south were observed on June 15, clouds obscured the volcano on
other days. According to satellite data, a big thermal anomaly was noted
on June 14-17 and 20.
KARYMSKY VOLCANO: 54œ03'N, 159œ27'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 all week. According to seismic data, possibly ash
explosions rose up to 5.8 km (~19,000 ft) ASL all days. According to
satellite data, volcano was obscured by clouds.
BEZYMIANNY
VOLCANO: 55œ58'N, 160œ36'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 data, weak gas-steam activity was observed
on June 15, 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.
