Las Pilas stratovolcano, seen here from the south, is the most prominent feature of Nicaragua's Las Pilas volcanic complex. Las Pilas barely exceeds 1000 m in elevation, but it towers 900 m above its base in the Nicaraguan depression only a few hundred m above sea level. Its broad 1088-m-high summit is cut by a 700-m-wide crater and by a N-S fissure formed during an eruption in 1952. There were no previously documented eruptions of this volcano since the arrival of Spanish explorers in the 1520s.
Lake-filled Laguna de Asososca maar, in the foreground, and the conical Cerro Asososca at the upper right were formed by eruptions at the southern end of a N-S fissure system of Las Pilas volcanic complex in Nicaragua. The ages of these vents are not known. This view looks from the NE across the broad plain at the foot of the Marrabios Range to the Pacific Ocean in the distance.
