KAMCHATKA:

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

According to seismic data, the explosive eruption of the volcano occurred from 21:45 UTC on December 16 till 04:00 UTC on December 17. Probably ash plumes rose > 10.0 km (>32,800 ft) ASL. But the activity of the volcano continues and could affect international and low-flying aircraft.

Seismic activity of the volcano significant decreased from 04:00 UTC on December 17. A magnitude of volcanic tremor decreased and now it obscured by seismic data of Klyuchevskoy volcano (the eruption of Klyuchevskoy volcano continues). No visual and video data because the volcano obscured by clouds. Ash fall occurred at Kozyrevsk village. Ash falls were not noted in the other villages. According to satellite data, ash plumes extended > 350 km (217 mi) to the north-west from the volcano.

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.
