BEZYMIANNY
VOLCANO: 55œ58'N, 160œ36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN
COLOR CODE IS YELLOW
Activity
of the volcano continues. Ash explosions up to 10 km (or 32,800 ft.) ASL are
possible during next weeks. The activity of the volcano could affect
international and low-flying aircraft.
Growth of the lava dome
continues. According to satellite data, an intensity of a thermal anomaly
over the lava dome slightly increased last week. Seismic activity did not exceed
background level on this week. According to visual data, a weak fumarolic
activity was noted at the dome on September 27-28 and October 01-02, clouds
obscured the volcano on 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 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 was above background levels. Many
shallow volcanic earthquakes and an intermittent volcanic tremor were registered
on September 27-29 and October 02-03. There was no seismic data in the other
days this week. According to seismic data, ash plumes up to 5.3 km (17,400 ft)
ASL occurred at the volcano on September 27-29. There were hot avalanches in
these days. According to video data, gas-steam plumes raising up to 4.5 and 3.5
km (14,800 and 11,500 ft) ASL were noted on September 27 and October 02,
respectively. There was a weak fumarolic activity on October 01. Clouds obscured
the volcano on the other days. According to satellite data, a big thermal
anomaly was noted all week. Ash plumes extended > 40 km (25 mi) to the
west-south-west and south-east from the volcano on September 27 and 29,
respectively.
KARYMSKY VOLCANO: 54œ03'N, 159œ27'E;
Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
The
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, many shallow volcanic earthquakes and a
spasmodic volcanic tremor were registered at the volcano all days. According to
seismic data, possibly ash explosions rose up to 3.5 km (11,500 ft) ASL all
week. According to satellite data, a thermal anomaly was noted on September 27,
29-30 and October 01 and 03, clouds obscured the volcano on the other days. Ash
plumes extended > 160 km (> 99 mi) to the south-east and east from the
volcano on September 30 and October 01 and 03.
CHIKURACHKI
VOLCANO 50œ19'N, 155œ28'E; Elevation 1,816 m
CURRENT LEVEL OF CONCERN COLOR
CODE IS ORANGE
The
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.
According to satellite data, gas-steam plume containing ash
extended > 100 km (> 62 mi) from the volcano to the east-south-east on
October 04, clouds obscured the volcano on the other days.
Chikurachki
volcano is not monitored with seismic instruments. KVERT has satellite
monitoring and receives occasional visual observations of this
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 Northern Kuriles
Volcanoes.
