The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

Tecapa is a complex basaltic-to-andesitic stratovolcano at the NW end of a cluster of volcanoes east of the Río Lempa between San Vicente and San Miguel volcanoes. 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.
