El Salvador, Nicaragua: El Salvador, Nicaragua. Fine photo of the volcanic arc including the bend in plate boundary, expressed in the alignment of the volcanoes. Cosiguina (see next frame) is at the corner where the plate margin changes strike. Landward of the volcano line is a wide easterly fault valley that has formed by back-arc extension. That east-southeast trending graben becomes wider and deeper to the south, where it contains huge lakes such as Lago Nicaragua (not in this view).
