The flat-topped summit of massive Santa Ana volcano appears at the right, with conical Izalco volcano at the left in this NW-looking view from the Zapotitán basin. The pyroclastic cone on the center skyline is Cerro Verde, and the brownish scoria cone below it is Cerro Marcelino. Historical eruptions have occurred from the summit crater of Santa Ana and satellitic cones such as Cerro Marcelino on its SE flank. Izalco volcano was born in 1770, and the saddle between Izalco and Cerro Verde increased 100 m in height in the century after 1866.
