Overview
Diky Greben is a lava-dome complex that formed in the center of the 20 x 25 km Pauzhetka caldera, which also contains the Kurile Lake caldera to the east. This large caldera was associated with eruption of the voluminous rhyolitic Golygin ignimbrite during the late Pleistocene, about 443,000 years ago. The initial Diky Greben eruptions took place about 7,600-7,700 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 1,600 years ago. A total of 9-10 km3 of dacitic and 2-3 km3 of andesitic lavas and tephras were erupted at this time. Two large craters and a few smaller vents were formed after this eruption.

About the Photo
Diky Greben, seen here from the E along the Ozernaya River, is a Holocene lava dome complex that formed in the center of the 20 x 25 km Pleistocene Pauzhetka caldera. Early activity took place around 6,000 years ago. There are thick lava flows N and S of Nepriyatnaya dome (left-center horizon), which forms the summit of the complex.
