SUMMARY OF LEVEL OF CONCERN COLOR CODES:
KAMCHATKA:
KARYMSKY: ORANGE
SHEVELUCH and BEZYMIANNY: YELLOW
KLYUCHEVSKOY, TOLBACHIK PLOSKY, KIZIMEN,
AVACHINSKY, KORYAKSKY, MUTNOVSKY and GORELY: GREEN
NORTHERN KURILE:
EBEKO, CHIKURACHKI and ALAID: GREEN
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 60-500 local seismic events were registering every day.
Numerous ash plumes and ash deposits extending for about 36-60 km (22-37 mi) to
the north and north-east 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 did not exceed 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. A lava
block is extruding at the dome summit. A preparation of new explosive eruption
occures.
Seismic activity was above background levels on April 01 and did not exceed
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.
According to the data by KVERT-staff a long fissure N-S direction and an
extrusive block were noted at the dome summit on April 01.

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.
