SUMMARY OF LEVEL OF CONCERN COLOR
CODES:
KAMCHATKA:
KORYAKSKY, KLYUCHEVSKOY, SHEVELUCH and
KARYMSKY: ORANGE
BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY,

KURILES:
CHIKURACHKI, EBEKO and ALAID: GREEN
KORYAKSKY VOLCANO; 53°19'N,
158°43'E; Elevation 3, 456 m
CURRENT LEVEL OF CONCERN COLOR CODE
IS ORANGE
Weak
explosive activity of the volcano continues. Probably activities of the volcano
will increase. The activity of the volcano is dangerous for low-flying
aircraft.
Seismic activity of the volcano was at background levels: from
one till seven volcanic earthquakes were noting each day at the volcano.
Possibly an episodes of volcanic tremor were registered on December 30-31 and
January 01. According to visual data, gas-steam plumes possibly containing small
amount of ash moves on the surface of north-western slope of the volcano on
December 30-31. Clouds obscured the volcano in the other days.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
Explosive-effusive
eruption of the volcano continues. Probably an ash explosive activity of the
volcano will grow. The activity of the volcano is dangerous for international
and low-flying aircraft.
Seismic activity of the volcano was above
background levels: a lot of volcanic earthquakes and continuous volcanic tremor
were registered at the volcano all week, but seismic activity of the volcano
slightly decreased. According to visual data on December 25, gas-steam plume
containing ash rose up to 5.5 km (18,000 ft) ASL. Lava effusion on the
north-western flank of the volcano continues. Strombolian activity of the
volcano was noted on December 25 and 27. Small ash fall at Kozyrevsk village was
noted on December 27. According to satellite data, a large thermal anomaly was
registered over the volcano all week. Ash plumes extended about 250 km (155 mi)
to the north-east from the volcano on December 25-26. There was noted an ash
cloud 6 km (4 mi) long in 34 km (21 mi) to the north-west from the
volcano.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the
dome elevation ~2,500 m
CURRENT LEVEL OF CONCERN COLOR CODE
IS ORANGE
The lava
flow continues to effuse on the southern and northern flanks of the lava dome.
Ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. The
activity of the volcano could affect international and low-flying
aircraft.
Seismicity was above background levels all week. According to
seismic data, probably ash plumes up to 7 km (23,000 ft) ASL occurred at the
volcano on December 25-26, and up to 5.5 km (18,000 ft) ASL in the other days
last week. According to visual data, an ash plume rose up to 5.5 km (18,000 ft)
ASL on December 25. Moderate gas-steam activity was noted on December 25 and 30
and January 01. Clouds obscured the volcano in the other days of the week.
According to satellite data, a big thermal anomaly was registered over the lava
dome all week. An ash plume extended about 40 km (25 mi) to the north-west from
the volcano on December
30.

KARYMSKY
VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
CURRENT LEVEL OF CONCERN COLOR
CODE IS ORANGE
Activity of
the volcano continues and ash explosions up to 6 km (or 19,700 ft.) ASL are
possible. The explosive activity of the volcano could affect low-flying
aircraft.
There was not seismic data all week by technical reasons.
According to satellite data, clouds obscured the volcano all
week.
BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Growth of the lava dome
continues. Sudden ash emission related to this activity could affect low-flying
aircraft in the vicinity of the volcano.
Strong seismicity of
Klyuchevskoy volcano does not allow to detach a seismicity of Bezymianny
volcano. A moderate fumarolic activity of the volcano was observed on web-camera
on December 25-26 and January 01. Clouds obscured the volcano in the other days
of the week. According to satellite data, the volcano was obscured by
clouds.

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 Kuriles Volcanoes.
