Conchagua is a conical, but deeply eroded basaltic to basaltic-andesite stratovolcano bordering the Gulf of Fonseca at the SE tip of El Salvador.  Cerro de la Bandera, east of Cerro del Ocote, the summit of Conchagua, appears to be younger in age.  Recently active fumarolic areas form barren spots on both peaks.  Eruptions reported  in 1522, 1688, 1868, and 1947 are erroneous, and may refer to landslides associated with earthquakes.
