SPECIAL NOTICE:
From May 06, AVO will no
longer relay email information releases from
KVERT. Information regarding
Kamchatkan volcano activity is sent
directly from KVERT staff in
Petropavlovsk-Kamchatsky.

SUMMARY OF LEVEL OF CONCERN
COLOR CODES:
KAMCHATKA:
SHEVELUCH and KARYMSKY:
ORANGE
BEZYMIANNY and KLYUCHEVSKOY: YELLOW
TOLBACHIK PLOSKY,
KIZIMEN, AVACHINSKY, KORYAKSKY, MUTNOVSKY and GORELY: GREEN
NORTHERN KURILE:
EBEKO: YELLOW
CHIKURACHKI and ALAID: GREEN
CURRENT CHANGES IN COLOR
CODE:
KLYUCHEVSKOY IS NOW AT LEVEL OF CONCERN COLOR CODE YELLOW
KLYUCHEVSKOY VOLCANO: 56o03'N, 160o39'E; Elevation
4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW.
PREVIOUS LEVEL OF CONCERN COLOR CODE:
GREEN.
Seismic activity of the volcano increased. Possibility of ash
explosions up to 5 km
(16,500 ft.) ASL exists.
An amplitude of a volcanic tremor grew. Weak gas-steam
activity and thermal anomaly were
registered this week.
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, as well as localized ash fall and
hot
avalanches. The new seismic station KB GS RAS began to work on the
eastern flank of the
volcano on September 12, 2005.
An effusion
of viscous lava flow at the lava dome continues. An incandescence at the
lava
dome was noted on September 13. Gas-steam plumes up to 3.5 km (or 11,500
ft.) ASL and a
large thermal anomaly were registered all
week.
KARYMSKY VOLCANO: 54o03'N,
159o27'E; Elevation 1,486 m.
CURRENT LEVEL OF
CONCERN COLOR CODE: ORANGE.
Seismic activity of the
volcano continues. The danger of a sudden explosion or series of
explosions
of ash up to 6 km (or 19,700 ft.) ASL, as well as localized ash fall and
hot
avalanches, exists.
According to seismic data, possible
small ash-gas plumes were registered all week. A
thermal anomaly was noted on
September 15.
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 than unrest of the
volcano continues.
A gas-steam
activity and a thermal anomaly at the lava dome were registered all
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, high 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.
