KARYMSKY
VOLCANO: 54o03'N, 159o27'E; Elevation 1,486 m.
CURRENT LEVEL OF CONCERN COLOR
CODE: 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.
Intermittent eruptive activity at the
volcano continues. According to seismic data, ash plumes rose up to 3,5 km
(11,470 ft) ASL this week. Big thermal anomaly over the volcanic crater was
observed during the periods of visibility of the volcano. Ash deposits extending
about 30 km (~19 mi) to west-southwest from the volcano were noted on May 4. The
activity of the volcano could affect low-flying aircraft in the vicinity of the
volcano.
SHEVELUCH VOLCANO: 56o38'N, 161o19'E; Elevation 3,283 m,
the dome elevation ~2,500 m.
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Growth of the lava
dome continues. Thermal anomaly was observed during the periods of visibility of
the volcano. Seismic activity was at background levels last week but ash
explosions up to 6 km (19,700 ft.) ASL could occur at any
time.
BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Growth of the lava dome continues.
An extrusive eruption occurs at the lava dome. Hot avalanche was observed on May
04. There is an explosive eruption of the volcano possibly during next four
weeks.
Seismic activity was above background levels on April 30 - May 3
and at background levels in the other days. Fumarolic activity and thermal
anomaly at the lava dome were noted during the 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 Service(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.
