SUMMARY OF LEVEL OF CONCERN
COLOR CODES:
KAMCHATKA:
SHEVELUCH, KARYMSKY:
ORANGE
BEZYMIANNY and KLYUCHEVSKOY: YELLOW
TOLBACHIK PLOSKY,
KIZIMEN, AVACHINSKY, KORYAKSKY, MUTNOVSKY and
GORELY: GREEN
NORTHERN KURILE:
EBEKO:
YELLOW
CHIKURACHKI and ALAID: GREEN
SHEVELUCH VOLCANO: 56o38'N, 161o19'E;Elevation 3,283
m, the dome elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE:
ORANGE
Growth of the lava dome continues. At any time explosions
could produce ash plumes that
rise as high as 8 km (or 25,000 ft.)
ASL.
Seismic activity of the volcano continues. Small hot
avalanches, weak ash-gas plumes and
thermal anomalies over lava dome were
noted this week.
KARYMSKY VOLCANO: 54o03'N, 159o27'E; Elevation 1,486
m.
CURRENT LEVEL OF CONCERN COLOR CODE: ORANGE.
Seismicity was above
background levels this week. A lava crust grows into the volcanic
crater from
beginning of September this year. The danger of ash explosions up to 8 km
(or
26,300 ft.) ASL significantly increased.
According to seismic data, possible small ash-gas plumes were
registered all week. A
thermal anomaly was noted on September 29-30 and
October 02-03.
KLYUCHEVSKOY VOLCANO: 56o03'N, 160o39'E; Elevation
4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW.
Seismic activity of the volcano continues. Possibility of ash
explosions up to 5 km
(16,500 ft.) ASL exists.
Shallow earthquakes and volcanic tremor, weak gas-steam
activity and weak thermal anomaly
were registered this
week.
BEZYMIANNY VOLCANO: 55o58'N,
160o36'E; Elevation 2,895 m
CURRENT LEVEL OF
CONCERN COLOR CODE: YELLOW.
The volcanological field research on July-September 2005
showed that unrest of the
volcano continues.
Gas-steam activity
and thermal anomaly at the lava dome were registered this
week.
EBEKO VOLCANO, Paramushir Island,
Northern Kurile: 50o41'N, 156o01'E Elevation 1,156 m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW.
Activity of the volcano
continues. Ebeko volcano is not monitored with seismic
instruments. KVERT has
satellite monitoring and occasional visual observations about this
volcano.
The danger of sudden ash explosions up to 3 km (9,840 ft.) ASL as well as
ash
falls at Severo-Kurilsk exists.
According to visual data,
moderate fumarolic activity of the volcanic crater continues.

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 Service(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.
