Global Volcanism Program | Image GVP-10697

Two major scarps cutting Mombacho volcano (left-center) were the sources of major debris avalanches.  The arcuate peninsula and island chain extending into Lake Nicaragua (known as Las Isletas or Isletas de Granada) was produced by collapse of Mombacho to the NE.  The island at the right is Zapatera, a small shield volcano and maar complex.  The lake at the far left fills late-Pleistocene Apoyo caldera, and the roughly N-S-trending Granada cinder cone alignment lies NNW of Mombacho and east of Lake Apoyo in this NASA Space Shuttle image (with north to the upper left).
