Bezymianny (Template:Langx Bezymyannyyi, meaning unnamed) is an active stratovolcano in Kamchatka, Russia. Bezymianny volcano had been considered extinct until 1955. Activity started in 1955, culminating in a dramatic eruption on 30 March 1956.<ref name="Gorshkov">Template:Cite journal</ref><ref>Template:Cite book</ref> This eruption, similar to the 1980 eruption of Mount St. Helens, produced a large horseshoe-shaped crater that was formed by a sector collapse and an associated lateral blast. Subsequent episodic but ongoing lava dome growth, accompanied by intermittent explosive activity and pyroclastic flows, has largely filled the 1956 crater. The most recent eruption of lava flows occurred in February 2013.<ref name="KVERT1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> An explosive eruption on 20 December 2017 released an ash plume rising to a height of Template:Convert above sea level, which drifted for Template:Convert NE.<ref>Global Volcanism Program, 2017.

The eruption formed a column of ash that rose to a height of Template:Convert and was drifting to the southeast slowly. The ash plume stretched out across a distance of Template:Convert.Template:Cn
The modern Bezymianny volcano, much smaller than its massive neighbors Kamen and Kliuchevskoi, was formed about 4700 years ago over a late-Pleistocene lava-dome complex and an ancestral volcano that was built between about 11,000–7000 years ago. There have been three periods of intensified activity in the past 3000 years.
