SUMMARY OF LEVEL OF CONCERN COLOR
CODES:
KARYMSKY: ORANGE
SHEVELUCH, BEZYMIANNY and AVACHINSKY: YELLOW
KLYUCHEVSKOY, TOLBACHIK PLOSKY, KIZIMEN, KORYAKSKY, MUTNOVSKY and GORELY:
GREEN
NORTHERN
KURILE:
EBEKO: YELLOW
CHIKURACHKI and ALAID: GREEN
KARYMSKY VOLCANO: 54o03'N, 159o27'E; Elevation 1,486
m.
CURRENT LEVEL OF CONCERN COLOR CODE: ORANGE.
Seismicity was above background levels this week. The growth
of the lava dome in the
volcanic crater continues and a possibility of ash
explosions up to 6 km (or 26,300 ft.)
ASL exists.
According to seismic data, possibly five gas-steam plumes with
some amount of ash up to
3.0-3.5 km (9,800-11,500 ft.) ASL occurred this
week. A thermal anomaly was noted over
the volcano on November 03-05 and
07.
SHEVELUCH VOLCANO: 56o38'N, 161o19'E; Elevation 3,283
m, the dome elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Growth of the lava dome continues. Installation of new three
seismic stations at
Sheveluch volcano allows to carry out a correct seismic
monitoring of this volcano.
Possibility of ash explosions up to 6 km (19,600
ft.) ASL exists.
Weak seismicity, fumarolic activity and thermal anomaly over
the lava dome were
registered this week.
AVACHINSKY: 53o15'N, 158o51'E; Elevation 2,751
m.
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Shallow earthquakes in the edifice of Avachinsky volcano were
registered this week and
a weak thermal anomaly over the volcanic summit was
noted in satellite imagery on
November 07. From November 07 till now
the volcano is obscured by clouds due to heavy
storm. The possibility of
sudden ash explosions exists.
BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW.
Activity of the lava dome continues. Thermal anomaly at the
lava dome was registered
this week.
EBEKO VOLCANO, Paramushir Island, Northern Kurile:
50o41'N, 156o01'E Elevation 1,156 m
CURRENT LEVEL OF CONCERN COLOR CODE IS
YELLOW
Ebeko volcano is not
monitored with seismic instruments. KVERT uses satellite
monitoring and
receives occasional visual observations from Paramushir Island.
Moderate
fumarolic activity of the volcano continues. The danger of sudden
ash explosions up to 3
km (9,840 ft.) ASL exists.

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.
