CURRENT CHANGES IN COLOR
CODE:
KLYUCHEVSKOY IS NOW AT LEVEL OF CONCERN COLOR CODE GREEN
KLYUCHEVSKOY VOLCANO; 56° 03'N,
160° 39'E; Elevation 4,750 m
CURRENT LEVEL OF CONCERN COLOR CODE IS GREEN
PREVIOUS LEVEL OF CONCERN COLOR CODE
IS YELLOW
Seismic activity
decreased to background levels on May 12 and remains the same till present. A
weak intermittent volcanic tremor continues to register in the area of the
volcano. A moderate and weak fumarolic activity of the volcano continues.
According to satellite data, the volcano is quiet.
However sometimes
gas-steam and/or aerosol plumes from the volcano could affect low-flying
aircraft.

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: a new viscous 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, possibly ash plumes rose up to 4.8-7.7 km (15.700-25.250 ft) ASL
on June 06 and 10-11, and weak ash plumes occurred at the volcano this week.
According to video data, strong and moderate gas-steam activity of the volcano
was observed last week. According to satellite data, a thermal anomaly was
registered over the lava dome all week. Ash plumes extended about 90 km (56 mi)
to the south from the volcano on June 06-07

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
Activity of the volcano
continues and 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 above background levels all week. According to
seismic data, a weak spasmodic volcanic tremor was registered at the volcano
this week. Possibly weak ash plumes occurred at the volcano. According to
satellite data, there were noted: a weak thermal anomaly over the volcano on
June 04-06, and gas-steam plumes extending about 30 km (19 mi) to the south-east
from the volcano on June 04.

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 aerosol plumes could affect low-flying
aircraft.
Seismic activity of the volcano was at background levels all
week. According to visual data, a strong and moderate fumarolic activity of the
volcano was observed all week. According to satellite data, the volcano was
quiet.

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
was slightly above background levels on June 05 and didn't exceeded background
levels in the other days of week. A weak fumarolic activity of the volcano was
observed on June 04 and 06. According to satellite data, a thermal anomaly was
noted over the lava dome on June 07.

EBEKO VOLCANO, Paramushir Island, Northern Kurily: 50°41'N,
156°01'E; Elevation 1,156
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Activity of the volcano
continues. Moderate gas-steam emission sometimes with small amount of ash occur
at Ebeko. 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.
Gas-steam plumes rose up to 2.7 km (8,900 ft) ASL on June
09-10. According to satellite monitoring, there were not registered 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.
