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

KARYMSKY
VOLCANO: 54œ03'N, 159œ27'E; Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR
CODE IS ORANGE
Seismic
data and satellite observations indicated that a moderate ash 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 weak local shallow
earthquakes was 100-250 per day. Possibly, ash explosions from the volcano rose
about 4.5 km (14,800 ft)ASL on September 22 and up to 2.5 km (8,200 ft) ASL in
the other days. A thermal anomaly over the volcanic crater was noted on
September 23 and 26-27.
BEZYMIANNY VOLCANO: 55œ58'N, 160œ36'E;
Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Seismic data and
satellite observations indicated that growth of the lava dome continues. The
activity of the volcano could affect low-flying aircraft in the vicinity of the
volcano.
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 recorded on September 23
and 26. 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. A thermal anomaly over the volcanic crater was noted on September
22.

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.
