Global Volcanism Program | Image GVP-10695

Two lake-filled calderas dominate the 11-km-wide Chiltepe Peninsula extending NE-ward into Lake Managua.  Greenish Lake Apoyeque was the source of two major late-Pleistocene plinian pumice deposits, and dark-blue Lake Jiloa (Xiloa) produced the Jiloa Pumice about 6500 years ago.  The two calderas cut the summit of the Chiltepe pyroclastic shield volcano.  Nicaragua's capital city Managua, extending across much of the right side of the image, has been subjected to major tectonic earthquakes.
