Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Las Pilas-El Hoyo Complex
Las Pilas volcanic complex includes a cluster of cones, of which Las Pilas (El Hoyo), in the center background, is the largest. A N-S fracture system cutting across the cone has produced numerous well-preserved flank vents, including maars. Cerro Asososca is the prominent conical volcano in the right foreground of this photo from the SW. Cerro Grande is the peak at the upper left. The only certain historical eruptions of Las Pilas took place in the 1950s from a fissure that cut across the summit east of the 700-m-wide summit crater. Photo by Jaime Incer, 1981

Las Pilas-El Hoyo volcanic complex, overlooking Cerro Negro volcano to the NW, includes a diverse cluster of cones within about a 3-km-diameter area. A N-S-trending fracture system cutting across the edifice is marked by numerous flank vents, including maars, that are part of a 30-km-long volcanic massif. The Cerro Negro chain of cinder cones is listed separately in this compilation because of its extensive historical eruptions and possible distinct magmatic system. The lake-filled Asososca maar is located adjacent to the Cerro Asososca cone on the southern side of the fissure system, south of the axis of the Marrabios Range. Two small maars west of Lake Managua are located at the southern end of the fissure. Aside from a possible eruption in the 16th century, eruptions of Las Pilas took place in the 1950s from a fissure that cuts the eastern side of the 700-m-wide crater and extends down the N flank.
