Conchagua (also known as Cochague) is a conical edifice consisting of two overlapping stratovolcanoes, Ocotal and Banderas, overlooking the Gulf of Fonseca at the SE tip of El Salvador. It is elongated WSW-ENE, and the eastern and southern flanks descend into the sea. Cerro de La Banderas has a large horseshoe-shaped crater open to the NE, and though it appears younger, Ar-Ar dating by Quezada and Garcia (2008) was 0.41 +/- 0.1 Ma. To the WSW, the slightly higher Cerro del Ocotal, at 1225 m, was dated at 0.15 +/- 0.02 Ma. Ocotal has multiple peaks and the flanks are more dissected. Eruptions reported for the years 1522, 1688, 1868, 1892, and 1947 are erroneous, and may refer to landslides associated with earthquakes, an interpretation supported by Rapprich et al. (2010).
