KAMCHATKA:

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

Strong explosive eruption of Bezymianny volcano occurred from 12:30 till 12:50 UTC on May 31, according to seismic data. There were probably two general explosions of the eruption: about 12:30 and about 17:00 UTC. Ash plumes rose up to 8-10 km (26,240-32,800 ft) ASL and first ash plumes extended to the west from the volcano about 250 km (155 mi) and second ash clouds - to the north and the north-east about 160 km (99 mi).

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. Probably a viscous lava flow effuses on the slope of the lava dome.

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.

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.
