This false-color oblique DEM overlain by a thermal infrared ASTER image shows Santa Ana volcano (middle left), Izalco volcano (center), and the roughly 5.5 x 6 km Coatepeque caldera lake from the SW. The summit of Santa Ana has series of nested craters, and a NW-SE-trending fissure across the edifice. Lava flows were recently emplaced across the southern flanks of Izalco. The grayish area at the far upper left is the city of Santa Ana, El Salvador.
