CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE
PREVIOUS LEVEL OF CONCERN COLOR CODE IS YELLOW
Ash
explosions up to 10 km (32,800 ft.) ASL could occur at any time. The activity of
the volcano could affect international and local aircraft.
According to
satellite data on May 10, a large thermal anomaly with a temperature about 51
degrees of Celsius is noting at the area of lava dome of Bezymianny volcano.
This anomaly can reflection a strong extrusive proses at the dome or a strong
gas-steam emission from the dome. These data indicate that probably an explosive
eruption of the volcano can occur in rapid time.
Strong seismicity at
nearby Klyuchevskoy volcano makes it difficult to determine seismicity at
Bezymianny, and KB GS RAS' staff is unable to accurately determine the state of
the volcano from 15 April.

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.
