Eleven scoria cones have formed in the southern Colima graben near the flanks of Colima volcano since the late Pleistocene. Cerro la Erita, a 190-m-high cone, is seen here from the NE. Cerro el Petacál (top right) is a fault block of older rocks that rises above the graben floor. Sierra Manantlán forms the 1,700-m-high western graben wall on the SW block of the rift zone.
