Kronotsky, seen here from the SW, towers above extensively eroded pyroclastic flow deposits. These voluminous deposits were produced by Pleistocene explosive eruptions that resulted in formation of the Uzon and Krasheninnikov calderas. The initial caldera-forming eruption at Uzon dates back to the mid-Pleistocene. A younger caldera formed about 39,000 years ago and was followed shortly by formation of the Krasheninnikov caldera.
