SUMMARY OF AVIATION COLOR CODES:

KAMCHATKA:
SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE

BEZYMIANNY: YELLOW
TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, GORELY, MUTNOVSKY and KIZIMEN: GREEN

NORTHERN KURILES:
EBEKO, CHIKURACHKI and ALAID: GREEN


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 activity of the volcano continues. Moderate gas-steam activity with bursts of small amount of ash was observing on May 13-18. Clouds obscured the volcano in the other days of week. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending from 20 till 145 km (12-90 mi) to the eastern directions from the volcano were noted on May 14-15 and 17-19.

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 5.1 km (16,700 ft) ASL all week. According to visual data, moderate fumarolic activity was observed on May 15-17. 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. An ash plume extending ~40 km (25 mi) to the south-east from the dome was noted on May 15, and gas-steam plumes extending about 40 km (25 mi) to the north-east from the volcano - on May 18.

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 2.5 km (8,200 ft) ASL all week. According to satellite data, a thermal anomaly was registering over the volcano on May 13-17 and 19-20. An ash plume extending about 18 km to the north-east was noted on May 17.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
AVIATION COLOR CODE IS
YELLOW

Activity of the volcano continues and its aerosolic plumes could affect low-flying aircraft.

Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny last week. Moderate fumarolic activity of the volcano was observed on May 13 and 16. Clouds obscured the volcano in the other days. According to satellite data, a thermal anomaly over the lava dome was registering on May 14-16 and 19-20. A temperature of thermal anomaly began to increasing from May 19.

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.
