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 a moderate ash 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.
According to seismic data, a number of weak local shallow
earthquakes was 120-190 per day. Possibly, ash explosions from the volcano rose
up to 2.5 km (8,200 ft) ASL. A thermal anomaly over the volcanic crater was
noted on September 30, October 02 and 04. 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.
Seismic data and satellite
observations indicated that 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 September 28 and
30, and did not exceed background levels in the other days. Several weak shallow
earthquakes were registered this week. A fumarolic activity of the lava dome was
noted during periods of visibility of the volcano. A thermal anomaly over the
dome was recorded on October 01 and 04. 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 all week. Several
weak earthquakes were registered at the volcano last week. A fumarolic activity
of the lava dome was observed during periods of visibility of the
volcano.

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
