BackgroundCerro San Jacinto, also known as Cerro San Jacinto Viejo, is a small stratovolcano constructed along the eastern margin of the Nicaraguan central graben east of Lake Managua. A large central depression is surrounded on the north and east by a horseshoe-shaped ridge, which is a remnant of a caldera rim. San Jacinto was considered to be of possible Holocene age on the basis of youthful morphology (McBirney and Williams, 1965). However, the volcano is highly dissected relative to the Holocene volcanoes across the Nicaraguan depression to the west. Van Wyk de Vries (1999 pers. comm.) noted that the volcano is substantially older than nearby Las Lajas volcano and is of probable early Pleistocene age.
