Tecapa volcanTecapa volcano a complex basaltic-to-andesitic stratovolcano in east-central El Salvador. It is located at the NW end of a cluster of volcanoes east of the Río Lempa between San Vicente and San Miguel volcanoes.
Introduction:The Berlín caldera, whose rim is visible on the west side of the complex, was formed during the eruption of the Blanca-Rosa dacitic pumice in the late Pleistocene. Following caldera formation the cones of Cerro Las Palmas, Cerro Pelón, Tecapa-Laguna de Alegria, and Cerro Alegria were constructed along a WSW-ENE line. The crater of Tecapa-Laguna de Alegria contains a deep notch on the eastern rim and is filled by Laguna de Alegria crater lake. The Tecapa volcanic complex currently displays fumarolic activity, and a producing geothermal plant is located at the Berlín geothermal field.
