Before October of 1955 Bezymyannyi was considered as extinct volcano and as a matter of fact it even hadn't name. The name of Bezymyannyi may be translated into English as Nameless. In 1954 the study of this imperceptible (in comparison with surrounding volcanos) mount was entrusted to G. Bogoyavlenskaya. Then she was a young post-graduate. However Volcano awoke in October of 1955 and the gigantic eruption has taken place on March 30, 1956. After that some scientists of Kamchatka Volcanic Station began to speak as a joke: "Even the volcano does not stand up to the woman nature and flies into a rage..."
First indications of arousing Bezymyannyi are referred by September
29, 1955, when Kluchi Seismic Station began to record earthquakes from
Volcano. The first historical eruption began about 6 clocks 30 minutes
October 22, 1955.
