BEZYMIANNY VOLCANO: 55œ58'N, 160œ36'E; Elevation
2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
Growth of the lava dome continues.
The activity of the volcano could affect low-flying aircraft in the vicinity of
the volcano.
According to seismic data from Kozyrevsk, probably the
explosive eruption occurred at Bezymianny volcano from 14:30 till 15:00 UTC on
May 11. According to satellite data, an ash plume extended to the north from the
volcano. The ash fall was observed at Klyuchi from about 16:00 UTC till ~22:00
on May 11. Because the eruption of Klyuchevskoy volcano continued too ash
deposits at Klyuchi were a mix of ash from Bezymianny and a small part (as
addition) of ash from Klyuchevskoy. According to satellite data, large plumes
different directions were observed over the Northern Kamchatka from 16:00 UTC on
May 11. According to visual data from Kozyrevsk, at 22:30 UTC on May 11, there
was one of hot avalanches that happens after the eruption. Ash plume rose up to
4.0 km ASL. According to satellite data, a long thermal anomaly (11 pixels in
size) extending to the south-east from the lava dome was noted at 18:58 UTC on
May 12 (NOAA-15). Probably this anomaly reflection hot deposits of pyroclastic
flow.
Clouds obscured the volcano several last days.

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.
