UTC (Friday, July 04, 10:30 KDT)
SUMMARY OF LEVEL OF
CONCERN COLOR CODES:
KAMCHATKA:
SHEVELUCH: ORANGE
BEZYMIANNY and
KARYMSKY: YELLOW
KLYUCHEVSKOY, TOLBACHIK
PLOSKY, KIZIMEN, AVACHINSKY, KORYAKSKY, MUTNOVSKY and GORELY: GREEN
NORTHERN
KURILES:
CHIKURACHKI, EBEKO and ALAID: GREEN
SHEVELUCH VOLCANO: 56°38'N,
161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m.
CURRENT LEVEL OF
CONCERN COLOR CODE IS ORANGE
Activity
of the volcano continues (new portions of viscous lava extrudes at the dome) and
ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. The
activity of the volcano could affect international and low-flying
aircraft.
Seismicity was slightly above background levels all week:
volcanic earthquakes and a weak volcanic tremor were registered at the volcano
all week. According to seismic data, possibly ash explosions up to 3.7 km
(12,200 ft) ASL occurred on June 26. According to visual data, moderate
fumarolic activity of the volcano was observed on June 29 and July 01 and 03.
Clouds obscured the volcano in the other days. According to satellite data, a
bright thermal anomaly was registered over the lava dome on June 27-29 and July
1-3.
BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Growth of the
lava dome continues. Sudden ash emission related to this activity could affect
low-flying aircraft in the vicinity of the volcano.
Seismic activity of
the volcano did not exceed background levels last week. According to visual
data, a weak fumarolic activity of the volcano was registered on July 02-03.
According to satellite data, a weak thermal anomaly was noted over the lava dome
on June 28. Clouds obscured the volcano in the other days of
week.
KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m.
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Activity of the
volcano decreased but ash explosions up to 6.0 km (or 19,700 ft.) ASL are
possible. The explosive activity of the volcano could affect low-flying aircraft
in the vicinity of the volcano.
Seismic activity was at the background
levels all week. According to seismic data, possible very weak gas-ash
explosions occurred at the volcano all week. According to satellite data, a weak
thermal anomaly was noted over the volcano on June 29.

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 Kuriles Volcanoes.
