CURRENT CHANGES IN AVIATION COLOR CODE
KLYUCHEVSKOY IS NOW AT AVIATION COLOR CODE: ORANGE
KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750
m
CURRENT AVIATION COLOR CODE IS ORANGE
PREVIOUS AVIATION COLOR CODE WAS YELLOW
Activity of the volcano increased. Ash explosions > 6.0 km (>19,700 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.
Explosive eruption of the volcano began on September 18.
Seismicity was above background levels all week. Many volcanic earthquakes and weak volcanic tremor were registering into the volcanic edifice all week. According to visual data, weak Strombolian activity of the volcano was observed on October 02-03. A height of bursts was about 70-100 m above the crater. Fumarolic column containing small amount of ash rose up to 5.7 km (19,700 ft) ASL on October 07. Moderate fumarolic activity of the volcano was noted on October 02-03, clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly was registering over the volcano all week.

SHEVELUCH VOLCANO: 56°38'N,
161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION 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 6.8 km (22,300 ft) ASL on October 06, and up to 4.5 km (14,800 ft) ASL in the other days of last week. According to visual and video data, fumarolic plumes containing small amount of ash rose up to 4.0 km (13,100 ft) ASL on October 01-03. Clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly was registering over the lava dome all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486
m
CURRENT AVIATION COLOR CODE IS ORANGE
Activity of the volcano continues and ash explosions up to 6.0
km (or 19,700 ft) ASL possible. The explosive activity of the volcano could
affect low-flying aircraft.
Seismic activity of the volcano was above background levels last week. Probably weak ash explosions occurred at the volcano. According to the data by volcanologists who work now at the volcano, ash plume raising up to 3.5 km (11,500 ft) ASL and extending to the south-southeast from the volcano was observed at ~ 03:40 UTC on October 07. According to satellite data, the volcano was quiet last week.

KORYAKSKY VOLCANO; 53°19'N, 158°43'E; Elevation 3,456
m
CURRENT AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues and gas-steam plumes and
possible ash plumes could affect low-flying aircraft.
Seismicity didn't exceeded background levels all week. Moderate fumarolic activity of the volcano sometimes with weak emissions of ash was observed on October 01-03 and 05-07. According to satellite data, a weak thermal anomaly was registering over the volcano on October 02.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895
m
AVIATION 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.
Seismicity didn't exceeded background levels all week. Moderate fumarolic activity of the volcano was noted on October 02-03. Clouds obscured the volcano in the other days of week. According to satellite data, a weak thermal anomaly was registering over the lava dome on October 02-03 and 05-06.

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.
