This false-color NASA ASTER image (N is at the top) looks down on the 1.5-km-wide San Salvador summit crater. The lava flow to the north was erupted from a flank vent in 1917; the small cone in the center of the summit crater also formed that year. Lake-filled Laguna de Chanmico maar lies on the lower NW flank (left-center). The capital city of San Salvador is at the lower right.
