Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Apoyeque
Apoyeque stratovolcano forms the large Chiltepe Peninsula in central Lake Managua. A 2.8-km wide, 500-m-deep caldera truncates the volcano's summit, below and to the left of the airplane wing. Laguna de Jiloa, the large lake in the foreground, lies immediately SE of Apoyeque. The age of the latest eruption of Apoyeque is not known, but human footprints underlie pumice deposits thought to originate from Apoyeque volcano or a nearby vent beneath Lake Managua. Momotombo volcano is visible in the distance to the NW across Lake Managua. Photo by Jaime Incer, 1981.

The Apoyeque volcanic complex occupies the broad Chiltepe Peninsula, which extends into south-central Lake Managua. The peninsula is part of the Chiltepe pyroclastic shield volcano, one of three large ignimbrite shields on the Nicaraguan volcanic front. A 2.8-km wide, 400-m-deep, lake-filled caldera whose floor lies near sea level truncates the low Apoyeque edifice, which rises only about 500 m above the lake shore. The caldera was the source of a thick deposit of dacitic pumice that covers the surrounding area. The 2.5 x 3 km lake-filled Xiloá (Jiloá) maar is located immediately SE of Apoyeque. The Talpetatl lava dome was constructed between Laguna Xiloá and Lake Managua. Pumiceous pyroclastic flows from Laguna Xiloá were erupted about 6,100 years ago and overlie deposits of comparable age from the Masaya Plinian eruption.
