Ringkasan geologi
The modern Bezymianny, much smaller than its massive neighbors Kamen and Kliuchevskoi on the Kamchatka Peninsula, was formed about 4,700 years ago over a late-Pleistocene lava-dome complex and an edifice built about 11,000-7,000 years ago. Three periods of intensified activity have occurred during the past 3,000 years. The latest period, which was preceded by a 1,000-year quiescence, began with the dramatic 1955-56 eruption. This eruption, similar to that of St. Helens in 1980, produced a large open 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.

Ringkasan InggrisBezymianny 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. 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. 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. The volcano erupted similarly on 28 May 2022, again spewing an ash plume over 15 kilometres (49,000 ft) high. On April 7, 2023, Russia reported Bezymianny had erupted explosively again and the Federal Agency for Air Transport, Rosaviatsiya, issued a Notice to Airmen (NOTAM) and raised the aviation Color Code Red. The eruption formed a column of ash that rose to a height of 12 kilometres (39,000 ft) and was drifting to the southeast slowly. The ash plume stretched out across a distance of 2,000 kilometres (1,200 mi).
