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, sometimes ash plumes up to 5.4 km (17,700 ft) ASL occurred at the volcano. According to video data, an ash plume rose up to 5 km (16,400 ft) ASL from a hot avalanche on May 13. Strong gas-steam activity of the volcano was observed on May 11-12. The volcano was obscured by clouds in the other days of 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 at background levels all week. According to visual data, a strong fumarolic activity of the volcano was observed on May 10-12, gas-steam plumes extended to the south and south-east from the volcano. 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 May 07-11 and at background levels on May 12-13. A weak volcanic tremor and shallow seismic events were registered in the area of the volcano all week. A moderate and strong fumarolic activity of the volcano was observed at the volcano on May 07, 09-11. A gas-steam plume rose up to 6.8 km (22,300 ft) ASL on May 11, and extended to the north-west from the volcano. The volcano was obscured by clouds in the other days of the week. According to satellite data, a weak thermal anomaly was noted over the volcano on May 07 and 12. A gas-steam plume extending about 14 km (8.7 mi) to the south-west from the volcano was registered on May 11.

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 above background levels on May 09-12 and at background levels in the other days. 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 didn't exceeded background levels last week. A weak fumarolic activity of the volcano was observed on May 07 and 10, 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 07.

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 on May 07-10 and at background levels on May 11-13. KVERT continues to watch the Gorely volcano.
According to visual data, a weak or moderate gas-steam activity of the volcano was observed on May 07 and 10-13. Clouds obscured the volcano in the other days of week. According to satellite monitoring, a weak thermal anomaly over the volcano was registered on May 11-12.

EBEKO VOLCANO, Paramushir Island, Northern Kurile: 50°41'N,
156°01'E; Elevation 1,156
CURRENT LEVEL OF CONCERN COLOR CODE: YELLOW
Activity of the volcano continues. 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), gas-steam plumes containing a small amount of ash rose up to 1.5-2.7 km (4,900-8,860 ft) ASL and extended about 9 km (5 mi) from the volcano. A weak ash fall was noted at Severo-Kurilsk on May 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.
