KARYMSKY
VOLCANO: 54œ03'N, 159œ27'E; Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR
CODE IS ORANGE
A moderate
explosive eruption of the volcano 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.
There was no seismic
data during the past week due to technical reasons. According to satellite data,
a big thermal anomaly over the dome was noted on November 26-27 and 29. Ash
plumes extended from the volcano for about 100-146 km (62-91 mi) to the
north-east on November 29. Clouds obscured the volcano in the other
days.
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.
Seismic activity was slightly above background
levels on November 25, 27 and at background levels in the other days. According
to visual and video data, a fumarolic activity of the volcano was observed on
November 27-28. According to satellite data, a thermal anomaly over the dome was
noted on November 26-28. Clouds obscured the volcano in the other
days.
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. Ash explosions up to 6 km (19,700 ft.) ASL could occur at any time.
The activity of the volcano could affect low-flying aircraft in the vicinity of
the volcano.
Seismic activity was at background levels on November 23-24
and 27-28 and did not exceed levels of registration in the other days. According
to visual and video data, a fumarolic activity of the volcano was observed on
November 27-28. Clouds obscured the volcano in 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 Kurile Volcanoes.
