(11) Volcanic Activity Summary:The extrusive-effusive eruption of the volcano continues, a strong fumarole activity, and sometimes an incandescence of the lava dome, and hot avalanches accompanies this process. But the activity of the volcano significantly decreased. Satellite data by KVERT showed a weak thermal anomaly over the volcano. KVERT continues to monitor Bezymianny volcano.

(14) Remarks:Bezymianny volcano is the most active volcano of the world. In 1955, for the first time in history, Bezymianny started to erupt and after six months it produced a catastrophic eruption with the total volume of eruptive products over 3 km3. The lava dome began to grow in the explosive crater immediately after the catastrophe and continues at now.
