KVERT INFORMATION RELEASE 33-10
July 02, 2010, 04:35 UTC (16:35 KDT)
SUMMARY OF AVIATION COLOR CODES:
KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE
GORELY and BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY and KIZIMEN: GREEN
NORTHERN KURILES:
EBEKO: YELLOW
CHIKURACHKI and ALAID: GREEN
EBEKO VOLCANO, Paramushir Island, Northern Kurile: 50o41'N, 156o01'E Elevation 1,156 m
AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE IS GREEN
Activity of the volcano increases. Ebeko volcano is not monitored with seismic instruments. KVERT has satellite monitoring and occasional visual messages about this volcano. The danger of sudden ash explosions as high as 3 km (9,840 ft.) ASL as well as ash falls at Severo-Kurilsk, exists.
According to the data by local observers at Severo-Kurilsk, activity on the volcano increases. Ash explosions at the volcano began to occur from 03:53 UTC on July 02. A height of ash column was about 1.8 km ASL. Ash plume extends to the south-south-east - to Severo-Kurilsk. KVERT continues to monitor the volcano.

KLYUCHEVSKOY VOLCANO; 56° 03'N, 160° 39'E; Elevation 4,750 m
AVIATION COLOR CODE IS ORANGE
Explosive-effusive eruption of the volcano continues. Ash explosions
> 7.0 km (> 23,000 ft) ASL could occur at any time. The activity
of the volcano could affect international and low-flying aircraft.
Seismicity of the volcano was above background levels all week. According to visual data, Strombolian and moderate gas-steam activity of the volcano were observing on June 24 and 29. Sometimes ash columns rose up to 5.3 km (17,400 ft) ASL. Clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the volcano all week. A gas-steam plume containing ash extended about 32 km to the south from the Volcano on July 01.

SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive eruption of the volcano continues. 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 6.6 km (21,600 ft) ASL on June 24, 27 and 29-30. Seismicity was increased from 01:54 till 09:30 on July 01, possibly ash plumes rose up to 8 km (26,200 ft) ASL on this time. According to visual data, small ash fall was noted in Klyuchi village on July 01. Ash plumes from hot avalanches rose up to 4.5 km (14,800 ft) ASL on June 24 and 29, and strong fumarolic activity were observed in these days. Clouds obscured the volcano in the other days. According to satellite data, a thermal anomaly was registering over the lava dome all week.

KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m
AVIATION COLOR CODE IS ORANGE
Explosive activity of the volcano continues. Ash explosions > 6.0 km
(> 19,700 ft) ASL could occur at any time. Aactivity of the volcano
could affect low-flying aircraft.
Seismic activity of the volcano was above background levels all week. According to seismic data, possibly ash plumes rose up to 6-7 km (19,700-23,000 ft) ASL on June 29 and July 01. According to satellite data, a thermal anomaly was registering over the volcano on June 27. Clouds obscured the volcano in the other days of week.

GORELY VOLCANO: 52°33'N, 158°02'E; Elevation 1,828 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano is increasing. Probably an eruption of Gorely is preparing. Aerosol plumes from the volcano could affect low-flying aircraft.
Seismicity of the volcano was above background levels all week. Amplitude of volcanic tremor was increasing up to 2 mkm/s on June 28-29 and remains on levels 1.7-1.8 mkm/s at present. Strong and moderate gas-steam activity of the volcano was observing on June 28 and 30. According to satellite data, the thermal anomaly over the volcano was registering on June 24-28. A gas-steam plume extended about 35 km to the south from the volcano on June 28. Clouds obscured the volcano in the other days.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS YELLOW
Activity of the volcano continues and aerosol plumes could affect low-flying aircraft.
Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny all week. According to visual data, clouds obscured the volcano all week. According to satellite data, a small thermal anomaly was registering over the dome on June 28.

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.
