Monte Bezymianny

Bezymianny

Estratovolcán · Russia · 2882 m

A lava dome fills much of the large horseshoe-shaped crater on the ESE side of Bezymianny in this late-1980s view from the SE. The crater formed during an eruption in 1955-56, which was similar to that of Mount St. Helens in 1980 with flank collapse and lateral blast components. Prior to this eruption Bezymianny had been considered extinct. Subsequent episodic lava dome growth, accompanied by intermittent explosive activity and pyroclastic flows, has largely filled the 1956 crater.

Resumen geológico

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.

Resumen de Wikipedia

El monte Bezymianny es un estratovolcán activo ubicado en la península de Kamchatka, Rusia. Se lo consideraba extinto hasta 1955, cuando sufrió una tremenda erupción de tipo peléano.
