A vertical aerial photo shows the unvegetated slopes and dark-colored lava flows of Volcán de Izalco, El Salvador's youngest volcano. It originated in 1770 CE on the southern flank of Santa Ana volcano, whose summit lies to the north (top). Steep-sided, 650-m-high Izalco stratovolcano is truncated by a 250-m-wide crater. The flanks of Izalco consist primarily of pyroclastic material erupted from the summit crater; lava flows mostly originated from vents on the lower flanks and were deflected southward by the slopes of Santa Ana volcano.
