Chronology of Bezymianny Volcano activity, 1956–2010

Bezymianny Volcano is one of the most active volcanoes in the world. In 1955, for the first time in history, Bezymianny started to erupt and after six months produced a catastrophic eruption with a total volume of eruptive products of more than 3km3.

Description
Summary:Bezymianny Volcano is one of the most active volcanoes in the world. In 1955, for the first time in history, Bezymianny started to erupt and after six months produced a catastrophic eruption with a total volume of eruptive products of more than 3km3. Following explosive eruption, a lava dome began to grow in the resulting caldera. Lava dome growth continued intermittently for the next 57years and continues today. During this extended period of lava dome growth, 44 Vulcanian-type strong explosive eruptions occurred between 1965 and 2012. This paper presents a summary of activity at Bezymianny Volcano from 1956 to 2010 with a focus on descriptive details for each event. •The work for the first time presents a summary of all 1956–2010 Bezymianny eruptions.•Bezymianny lava dome is developing since 1956 till present time.•In 1977–2010 forty strong explosive eruptions of Bezymianny occurred.•All Bezymianny explosive eruptions are accompanied by pyroclastic flows and surges.•Lava flow is effusing after explosions: by 2005 all dome slopes were covered by lava.
