The summit of Santa Ana features four nested calderas and volcanic craters, with the innermost containing a small crater lake Collapse of the summit during the late Pleistocene(inferring for underlying soil samples, the upper age limit is no so more than 57000 years ago ) produced a massive debris avalanche that reached the Pacific Ocean, forming the Acajutla Peninsula
