Krasheninnikov

Caldera · Russia · 1816m

Krasheninnikov is comprised of two overlapping edifices seen here from the north, with both cones topped by 800-m-wide craters. Construction of the northern cone (bottom) began about 6,500 years ago and eventually formed an inner cone within a 2-km-wide crater, the rim of which is visible to the left. The small inner cone of the northern crater was built during an eruption about 400 years ago which also produced a SW-flank lava flow.

Geological summary

The late Pleistocene to Holocene Krasheninnikov volcano is comprised of two overlapping stratovolcanoes within a 9 x 10 km Pleistocene caldera. Young lava flows from summit and flank vents descend both into the caldera and down its outer flanks, and older flows that covered much of the SE caldera rim extended downslope at least 7 km. Tephra deposits from the caldera-forming eruption directly overlie a 39,000 years before present (BP) tephra thought to be associated with the formation of Uzon caldera (Florenskii, 1988). The intra-caldera stratovolcanoes are situated along a NE-SW-trending fissure that has also produced zones of Holocene cinder cones extending 15-20 km beyond the caldera. Construction of the southern edifice began about 11,000 years BP and lasted for about 4,500 years; it has a summit crater about 800-900 m wide. The northern edifice was constructed during a cycle of similar length that began about 6,500 years ago; it has a summit crater about 1.5 km wide, within which is low cone with an 800-m-wide crater containing another small cone. An eruptive cycle during about 600-400 years BP (1350-1550 CE) produced the Pauk lava cone in the crater of the northern cone and the Yuzhny lava flow on SW flank outside the caldera, followed by the Molodoy flow from the upper SW flank (Ponomareva, 1987; Ponomareva and Tsyurupa, 1985; Ponomareva and Braitseva, 1990).

From Wikipedia

Krasheninnikov is a complex of two overlapping stratovolcanoes inside a large caldera on the eastern coast of Kamchatka Peninsula, Russia. It is located in Kronotsky Nature Reserve to the south of Lake Kronotskoye, and is named after explorer Stepan Krasheninnikov.
