These paired photos show Sheveluch volcano from the south before (top) and after (bottom) a major eruption in 1964. A brief, but powerful eruption on 12 November 1964 resulted in collapse of the south summit of Sheveluch (Crater Top), forming a 1.5 x 3 km open crater seen in the bottom photo. A large debris avalanche swept to the south, after which a Plinian eruption with an ash plume 10-15 km high produced pumice fall and pumiceous pyroclastic flow deposits.
