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.
Strombolian-volcanian activity of the volcano continues. Big
thermal anomaly over the volcanic crater was noted during the periods of
visibility of the volcano. About 50-400 local seismic events were registering
every day. Numerous ash plumes and ash deposits extending for about 10-40 km
(6-25 mi) to different directions from the volcano were observed on satellite
images. 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. A fumarolic activity and
thermal anomaly were 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. A current activity of the lava
dome: http://www.kscnet.ru/ivs/kvert/current/shv/new.html
BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Seismic activity was at background levels on March 23-24 and
28, and did not exceed background levels in the others days. Fumarolic activity
and thermal anomaly at the lava dome were noted during the periods of visibility
of the volcano. Based on past experience with Bezymianny a viscous lava flow is
probably active at the lava dome summit. There are no indications that an
explosive eruption is imminent next week.

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.
