CURRENT CHANGES IN AVIATION COLOR CODE:
KAMCHATKA:
AVIATION COLOR CODE OF BEZYMIANNY: ORANGE
NORTHERN KURILES:
AVIATION COLOR CODE OF ALAID IS YELLOW
BEZYMIANNY VOLCANO: 55°58'N,
160°36'E; Elevation 2,895 m
CURRENT AVIATION COLOR CODE IS ORANGE
PREVIOUS AVIATION COLOR CODE WAS YELLOW
Activity of the volcano gradually increased. Possibly a new explosive eruption of the volcano is preparing. The activity of the volcano could affect international and low-flying aircraft.
Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny but separate seismic signals in the area of the dome were registering last two days. Moderate fumarolic activity of the volcano was observed on May 21. Clouds obscured the volcano in the other days. According to satellite data, a temperature of thermal anomaly over the lava dome continues to increasing from 18 degrees of Celsius on May 19, to 48.8 degrees of Celsius on May 23.

ALAID VOLCANO: 50°52'N, 155°34'E; Elevation 2,339 m
CURRENT AVIATION COLOR CODE IS YELLOW
PREVIOUS AVIATION COLOR CODE WAS GREEN
Possibly activity of the volcano increased. Possibly a new explosive eruption of the volcano began to preparing. Ash explosions up to 10-15 km (>32,800-49,200 ft) ASL is typical for this volcano. The activity of the volcano could affect international and low-flying aircraft.
Alaid volcano is not monitored with seismic instruments - seismic station at the volcano is not working long time by technical reasons. KVERT has satellite monitoring and occasional visual messages about this volcano.
According to satellite data, a gas-steam plume about 11 km (6.8 mi) extending to the east-southeast from the volcano was noted on May 23, 2010 (NOAA-15, 19:23 UTC).
The volcano-Island, the most northern in the Kurile archipelago, is situated at a distance 30 km north-west from Paramushir and 70 km south-west from Kamchatka. The stratovolcano belongs to the Somma-Vesuvius type. The central scoria cone with the height of 250 m is situated inside summit crater. There are 33 lateral cones on the flanks of the volcano.
Last strong explosive eruption from the summit crater with vulcanian, vulcano-strombolian and subplinian types of activity occurred in 1981.
Alaid exposes high potential hazard to the aircrafts flying over Kamchatka and the Northern Kuriles because its eruptive clouds can rise to a height of 10-15 km above the crater and extend for hundreds of kilometers (up to 1500 km) and the duration of eruptions can exceed a few months.

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.

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.
