SUMMARY OF LEVEL OF CONCERN COLOR
CODES:
KAMCHATKA:
KARYMSKY : ORANGESHEVELUCH and BEZYMIANNY: YELLOW

PLOSKY, KIZIMEN, AVACHINSKY, KORYAKSKY, MUTNOVSKY and GORELY: GREENNORTHERN KURILE:
EBEKO, CHIKURACHKI
and ALAID: GREENKARYMSKY VOLCANO: 54œ03'N, 159œ27'E; Elevation
1,486 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE.
Seismic data and satellite
observations indicated that the eruption of the volcano with ash explosions from
the summit crater continues. Ash explosions up to 6 km (or 19,700 ft.) ASL are
possible. The activity of the volcano could affect low-flying aircraft in the
vicinity of the volcano.
Eruptive activity at the volcano continues.
According to seismic data, ash plumes rose up to 4.0 km (13,100 ft) ASL this
week. A number of local shallow earthquakes was from 100 till 350 per day on
June 29-July 03 and increased to 1000 on July 04-05. Spasmodic volcanic tremor
was registering all days. According to the pilots reports, ash plumes of the
volcano rising up to 2.5 km (8,200 ft.) ASL and extending to the south-east on
June 30. A thermal anomaly over the volcanic crater was observed on June 30 and
July 01 and 06.
BEZYMIANNY VOLCANO: 55œ58'N, 160œ36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
According to
volcanologists' experience, growth of the lava dome continues. Lava effusion is
probably occurring at the lava dome. The activity of the volcano could affect
low-flying aircraft in the vicinity of the volcano.
Seismic activity did
not exceed background levels on June 29 and July 02-05 and there was no seismic
information on June 30 - July 01. According to video data, a fumarolic activity
of the lava dome was observed on July 01. A thermal anomaly was noted at the
volcano on July 04 and 06. Clouds obscured the volcano all
week.
SHEVELUCH
VOLCANO: 56œ38'N, 161œ19'E; Elevation 3,283 m, the dome elevation ~2,500
m.
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
Growth of the lava dome
continues. A fumarolic activity of the lava dome was observed on June 30 and
July 01-02. A thermal anomaly over the dome was noted on July 04. Seismic
activity was at background levels last week but ash explosions up to 6 km
(19,700 ft.) ASL could occur at any time.

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 Survey (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.
