Tolbachik is composed of two main edifices. The flat-topped Plosky Tolbachik (right) is located east of the older and higher Ostry Tolbachik cone (left). Lengthy rift zones extending NE and S of Plosky Tolbachik have erupted voluminous lava flows through the Holocene. The 1975-76 eruption from the summit and S-flank fissures was one of the largest historical basaltic eruption in Kamchatka. Photo by Oleg Volynets (Institute of Volcanology, Petropavlovsk).
