SUMMARY OF LEVEL OF CONCERN COLOR
CODES:
KAMCHATKA:
SHEVELUCH: ORANGE
KORYAKSKY, KLYUCHEVSKOY,
BEZYMIANNY, KARYMSKY and GORELY: YELLOW
TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY and MUTNOVSKY: GREEN
NORTHERN KURILES:
EBEKO:
YELLOW
CHIKURACHKI and ALAID: GREEN
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
Activity of
the volcano continues. Probably a new lava flow effuses at the lava dome.
Ash explosions > 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, ash plumes up to 6.7 km (20,100 ft) ASL occurred at the volcano.
According to visual data, the volcano was obscured by clouds all week. According
to satellite data, a thermal anomaly was registered over the lava dome all
week.

KORYAKSKY VOLCANO; 53°19'N, 158°43'E; Elevation 3,456
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
A gas-steam activity of the
volcano continues and aerosolic plumes could affect low-flying
aircraft.
Seismic activity of the volcano was above background levels on
May 03 and at background levels in the other days this week. According to visual
data, a moderate fumarolic activity was observed at the volcano on May 02 and
05-07. According to satellite data, the volcano was quiet.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Moderate fumarolic activity
of the volcano continues. Gas-steam and/or aerosol with ash plumes from the
volcano could affect low-flying aircraft.
Seismic activity was above
background levels on April 30 - May 01 and May 05-06 and at background levels in
the other days this week. A weak volcanic tremor and a number of shallow events
in the area of the volcano were registered all week. The volcano was obscured by
clouds all week. According to satellite data, a weak thermal anomaly was noted
over the volcano on May 02. A strong gas-steam plume extending about 50 km (31
mi) to the north-west from the volcano was registered on May 06-07.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Gas-steam activity of the
volcano continues but a possibility of ash explosions up to 6.0 km (or 19,700
ft) ASL remains. The explosive activity of the volcano could affect low-flying
aircraft.
Seismicity was at background levels last week but there was not
the data by technical reasons on May 03-05. According to satellite data, a weak
thermal anomaly was registered over the volcano on May 06.

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.
Seismic activity of the volcano
didn't exceeded background levels last week. A weak fumarolic activity of the
volcano was observed on May 04 and the volcano was obscured by clouds in the
other days of this week. According to satellite data, a weak thermal anomaly
over the dome was registered on May 02 and 06.

GORELY VOLCANO: 52°33'N, 158°02'E, Elevation 1,829 m
CURRENT
LEVEL OF CONCERN COLOR CODE IS YELLOW
Seismicity of the volcano was above background levels all week.
According to satellite data, the volcano was quiet. KVERT continues to watch the
Gorely volcano.
According to visual data, the volcano was quiet or
obscured by clouds all week. According to satellite monitoring, a weak thermal
anomaly over the volcano was registered on May 02 and 06.

EBEKO VOLCANO, Paramushir Island, Northern Kurile: 50°41'N,
156°01'E; Elevation 1,156
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Strong gas-steam emission
sometimes with ash occur at Ebeko at present. The danger of sudden ash
explosions up to 3.5 km (11,500 ft.) ASL exists. Activity of the volcano could
affect low-flying aircraft.
According to the data by observers from
Severo-Kurilsk (Paramushir Island), activity of the volcano continues. Gas-steam
plumes containing a small amount of ash were noted on May 02. Clouds obscured
the volcano in the other days of week. According to satellite monitoring, there
were not noted a thermal anomaly over the volcano and ash plumes.
Ebeko
volcano is not monitored with seismic instruments. KVERT uses satellite
monitoring and receives occasional visual observations from Paramushir
Island.

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.
