CURRENT CHANGES IN COLOR
CODE:
KARYMSKY IS NOW AT LEVEL OF CONCERN COLOR CODE YELLOW
KARYMSKY VOLCANO: 54œ03'N, 159œ27'E;
Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
PREVIOUS LEVEL OF CONCERN COLOR CODE IS
ORANGE.
Seismic data and satellite observations
indicated that the eruption of the volcano 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.
According to seismic data, a number of local
shallow earthquakes was 30-90 per day. A thermal anomaly over the volcanic
crater was noted on September 1-4. Clouds obscured the volcano in the other
days.
BEZYMIANNY VOLCANO: 55œ58'N,
160œ36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.
Growth of the lava dome continues. The
activity of the volcano could affect low-flying aircraft in the vicinity of the
volcano.
Seismic activity of the volcano was at
background levels. Several weak shallow earthquakes were registered this week. A
fumarolic activity of the lava dome was noted during periods of visibility of
the volcano. A thermal anomaly over the lava dome was noted on September 01 and
04. Clouds obscured the volcano in the other days.
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. Ash
explosions up to 6 km (19,700 ft.) ASL could occur at any time. The activity of
the volcano could affect low-flying aircraft in the vicinity of the
volcano.
Seismic activity was at background levels all
week. Several weak earthquakes were registered at the volcano last week. A
fumarolic activity of the lava dome was observed during periods of visibility of
the volcano.

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.
