Coatepeque caldera is seen here from its northern rim, with massive Santa Ana volcano in the background. Light-colored areas at the left and center are part of the caldera walls, which rise from 250 m to about one kilometer above the lake. The rounded summit behind the caldera rim at the left is Cerro Verde, which was erupted along a NW-SE-trending fissure cutting through Santa Ana.
