Kamchatkan
and Northern Kurile Volcanic Activity
INFORMATION RELEASE 44-05
Friday,
August 12, 2005, 10:50 KDT (21:50 UTC on August 11)
SUMMARY OF LEVEL OF CONCERN COLOR CODES:
KAMCHATKA:
SHEVELUCH and KARYMSKY:
ORANGE
BEZYMIANNY: YELLOW
KLYUCHEVSKOY, TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY,
KORYAKSKY, MUTNOVSKY and GORELY:
GREEN
NORTHERN KURILE:
EBEKO, CHIKURACHKI and
ALAID: GREEN
CURRENT CHANGES IN COLOR
CODE:
KLYUCHEVSKOY IS NOW AT LEVEL OF CONCERN COLOR CODE GREEN
EBEKO IS NOW AT LEVEL OF CONCERN COLOR CODE GREEN
KLYUCHEVSKOY VOLCANO: 56o03'N, 160o39'E; Elevation
4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE: GREEN.
PREVIOUS LEVEL OF CONCERN COLOR CODE: YELLOW.
Seismic activity decreased to background levels. A weak
fumarolic activity only was
observing at the volcano. An eruption of
Klyuchevskoy is not expecting next week.
EBEKO VOLCANO, Paramushir Island, Northern Kurile:
50o41'N, 156o01'E Elevation 1,156 m
CURRENT LEVEL OF CONCERN COLOR
CODE: GREEN.
PREVIOUS LEVEL OF
CONCERN COLOR CODE: YELLOW.
Ebeko volcano is not monitored with seismic instruments. KVERT
has satellite monitoring
and occasional visual messages about this volcano. A
weak fumarolic activity of the
volcano was observed this week. According to
satellite data, the volcano was quiet.
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 nearest seismic station
from the volcano was destroyed by the eruption of
February 28,
2005.
A persistent thermal anomaly all week, a fumarolic activity
and incandescence at the
lava dome on August 06, were registered this
week.
KARYMSKY VOLCANO: 54o03'N, 159o27'E; Elevation 1,486
m.
CURRENT LEVEL OF CONCERN COLOR CODE: ORANGE.
Seismic activity is above background levels. The danger of a
sudden explosion or series
of explosions of ash up to 4 km (or 16,500 ft.)
ASL, as well as localized ash fall and
hot avalanches, exists.
According to seismic data, possible ash-gas plumes up to 4 km
(or 13,100 ft.) ASL were
registered this week. According to visual data by
volcanologists, ash plumes rose up to 2
km (or 6,600 ft.) ASL on August
10-11. A thermal anomaly was registered on August 08-11.
BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW.
The volcanological field research and development on July 2005
showed that unrest at the
volcano continues.
A gas-steam activity and a thermal anomaly at the lava dome on
August 04-05, 08 and 11,
were registered this week.

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.
