Mombacho volcano in the background collapsed during the late Pleistocene, producing a debris avalanche that swept into Lake Nicaragua, deposting debris that accumulated to form the Aseses Peninsula in the foreground. The surface of the avalanche deposit lies below the lake surface immediately offshore of the mainland, creating the Bay of Aseses in the middle of the photo. Portions of the deposit rise above the lake surface, forming hundreds of small islands.
