Global Volcanism Program | Image GVP-11549

This false color NASA aerial oblique ASTER image shows Santa Ana volcano (middle left), Izalco volcano (center), and lake-filled Coatepeque caldera from the SW.  The summit of Santa Ana is truncated by a series of nested craters, and a NW-SE-trending fissure cuts across the massif.  Fresh lava flows drape Izalco volcano, active from 1770 to 1966, and descend its southern flanks.  The grayish area at the far upper left is the city of Santa Ana, El Salvador's second largest city.
