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

CURRENT CHANGES IN AVIATION COLOR CODE:
AVIATION COLOR CODE OF BEZYMIANNY: YELLOW

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

The explosive eruption of Bezymianny volcano is finished but strong gas-steam emissions from the lava dome continues. The activity of the volcano could affect low-flying aircraft.

Strong explosive eruption of Bezymianny volcano occurred from 12:30 till 12:50 UTC on May 31, according to seismic data. Ash plumes rose up to 8-10 km (26,240-32,800 ft) ASL and extended about 250 km (155 mi) to the west from the volcano, about 160 km (99 mi) to the north and the north-east and > 600 km (372 mi) to the south and south-east from the volcano. Probably pyroclastic flow deposits were formed on the slope of the volcano - two bright thermal anomalies can see on the satellite images on June 01-02. Probably a viscous lava flow effuses on the slope of the lava dome.

Strong volcanic activity of Klyuchevskoy volcano obscured again a seismic data of Bezymianny on June 01-03. Moderate fumarolic activity of the volcano was observed on June 01. Clouds obscured the volcano on June 02.

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 all week. Ash columns rose up to 7.25 km (23,780 ft) ASL on June 01. According to satellite data, a big thermal anomaly was registering over the volcano all week. Ash plumes extending about 40 km (25 mi) to the north-west from the volcano were noted on May 28 and 31.

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 6.1 km (20,010 ft) ASL all week. According to visual data, ash plumes rose up to 4.5 km (14,800 ft) ASL all week, strong fumarolic activity was observed all week. Hot avalanches were noting in the dark time. According to satellite data, a big thermal anomaly was registering over the lava dome all week. An ash cloud 20x6 km in size was detected in ~15 km (9 mi) to the north from the dome on May 31. Gas-steam plumes extended about 30 km (19 mi) to the west from the volcano on May 29.

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 4 km (13,100 ft) ASL all week. According to satellite data, a thermal anomaly was registering over the volcano all week. Ash plumes extending about 30 km (19 mi) to the south from the volcano were noted on June 01.

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.
