EBEKO, CHIKURACHKI and ALAID: GREENKARYMSKY 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.
Seismic activity was above background
levels on November 10-11 and there was no seismic data in the other days. A
number of weak local shallow earthquakes was about 130-420 per day in these
days. Possibly, ash explosions from the volcano rose up to 2,5 km (8,200 ft) ASL
on November 10-11. According to satellite data, ash plume extended from the
volcano for about 35 km (22 mi) to the west on November 13. 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 at
background levels on November 09, 11-12 and did not exceed levels of
registration in the other days. According to visual and video data, a weak
fumarolic activity was observed on November 10 and 13-15. According to satellite
data, a thermal anomaly over the dome was noted on November 10-13. 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 last week.
According to visual and video data, a weak fumarolic activity was observed on
November 13-15. According to satellite data, a thermal anomaly over the dome was
noted on November 10-12. 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.
