Kamchatkan and Northern Kurile Volcanic
Activity
INFORMATION RELEASE 34-05
Friday, June 17, 2005, 10:30 KDT (21:30
UTC on June 16)
SUMMARY OF LEVEL OF CONCERN COLOR CODES:
KAMCHATKA:
SHEVELUCH: ORANGE
KLYUCHEVSKOY, BEZYMIANNY and KARYMSKY: YELLOW.
TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY, KORYAKSKY,
MUTNOVSKY and GORELY: GREEN
NORTHERN KURILE:
CHIKURACHKI, ALAID, EBEKO: GREEN
SHEVELUCH VOLCANO: 56o38'N,
161o19'E;
Elevation 3,283 m, the dome elevation ~2,500
m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE.
Growth of the Sheveluch lava dome continues. At any time
explosions could produce ash plumes that rise as high as 6 km or 20,000 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 at the dome and gas and steam
plumes were observed.
KLYUCHEVSKOY VOLCANO: 56o03'N, 160o39'E; Elevation
4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
Based on the weak volcanic tremor and several shallow
earthquakes at the volcano we suggest that possibility of ash explosions as high
as 6 km (or 19,700 ft ) ASL remains with little or no
warning.
This week gas-steam plumes rose up to 300 m above the crater
(or 16,600 ft ASL) on June 9.
KARYMSKY VOLCANO: 54o03'N, 159o27'E; Elevation 1,486
m.
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW..
Seismic activity remains slightly above background levels.
Unrest at the volcano continues.
According to seismic data, there were no ash-gas explosions
last week.
BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
Based on the persistent thermal anomaly at the dome during
previous weeks and gas and steam plumes, we suggest that unrest at the volcano
continues.
Clouds obscured the volcano last 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
Experimental and Methodical Seismological Department (KEMSD) 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.
