Diky Greben is a late-stage Holocene lava-dome complex that formed in the center of the 20 x 25 km Pauzhetka caldera. This large caldera was associated with eruption of the voluminous rhyolitic Golygin ignimbrite during the late Pleistocene, about 0.443 million years ago. Both Diky Greben and the Kurile Lake caldera, immediately to the east, are Holocene volcanoes constructed within the Pauzhetka caldera. The initial eruptions of Diky Greben took place about 7600-7700 years ago, immediately following the Kurile Lake eruption. Most of the volcano, particularly the thick lava flows north and south of Nepriyatnaya Mountain, was formed during an eruption about 1600 years ago. A total of 9-10 cu km of dacitic and 2-3 cu km of andesitic lavas and tephras were erupted at this time. Two large craters and a few smaller vents were formed after this eruption.

Diky Greben, seen here from the east along the Ozernaya River, is a Holocene lava-dome complex that formed in the center of the 20 x 25 km Pleistocene Pauzhetka volcano-tectonic depression. The initial eruptions of Diky Greben took place about 6000 years ago. Most of the volcano, particularly the thick lava flows north and south of Nepriyatnaya Mountain (left center horizon), which marks the 1070-m summit of the complex, were formed about 2000-1500 years ago.

The Diky Greben lava-dome complex is reflected in the waters of Kurile Lake caldera. The initial eruptions of Diky Greben took place about 6000 years ago, about 2000 years after formation of the 10-km-wide Kurile Lake caldera. The eastern lava dome, seen here, is breached to the east, and was formed during the early stage of eruptions from Diky Greben. Most of Diky Greben volcano, including the unvegetated thick lava flow visible south (left) of the summit, was constructed about 2000-1500 years ago.
