The Diky Greben lava dome complex rises above Kurile Lake caldera. Early eruptions took place about 6,000 years ago, about 2,000 years after formation of the 10-km-wide caldera. The eastern lava dome, seen here, opens to the E. Most of the edifice, including the unvegetated thick lava flow visible to the S (left) of the summit, was constructed about 2,000-1,500 years ago.
