Bezymianny (Russian: Безымянный 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.[2][3] This eruption, similar to that of Mount St. Helens in 1980, produced a large horseshoe-shaped crater that was formed by collapse of the summit 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.[4] An explosive eruption on 20 December 2017 released an ash plume rising to a height of 15 kilometres (49,000 ft) above sea level, which drifted for 320 kilometres (200 mi) NE.[5] The volcano erupted similarly on 28 May 2022, again spewing an ash plume over 15 kilometres (49,000 ft) high.[6]

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.

Besymjanny (russisch Безымянный) ist ein aktiver Schichtvulkan auf der Halbinsel Kamtschatka im Osten Russlands. Der Name des Berges bedeutet Der Namenlose. Besymjanny liegt an der südöstlichen Flanke des erloschenen Vulkans Kamen in der Kljutschewskaja-Sopka-Stratovulkangruppe (in der Literatur auch in der abweichenden Transkription Kliuchevskoi-Bezymianny-Vulkankomplex), zu der auch der Schiwelutsch gehört.- [en] Bezymianny

Le Bezymianny, en cyrillique Безымянный, terme russe qui signifie littéralement « sans nom » en français, est un volcan de Russie situé dans la péninsule du Kamtchatka. Il est voisin des volcans Kamen, Ouchkovski et Klioutchevskoï situés immédiatement au nord et du Tolbatchik situé au sud. Alors considéré comme éteint, le volcan entame une nouvelle phase éruptive en 1955 lorsqu'il entre dans une violente éruption qui sera suivie par des dizaines d'autres.[it] Bezymjannyj
Il Bezymjannyj (in russo Безымянный) è uno stratovulcano della Kamčatka, in Russia. Il suo nome significa in lingua russa vulcano senza nome; lo si riteneva estinto fino al 1955 quando ha ripreso una forte attività. Fa parte del gruppo di vulcani del Ključevskaja Sopka, una formazione di vulcani posta a oriente della Catena Centrale, nella parte settentrionale della penisola. La formazione è tipica dei vulcani presenti in una zona di subduzione, nello specifico dello scorrimento della placca pacifica sotto quella euroasiatica.[ru] Безымянный (вулкан на Камчатке)
