Photo Gallery

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.

Conchagüita (left), an island in the Gulf of Fonseca, and Conchagua (right) a volcano on the Salvadoran mainland are seen here across the Gulf of Fonseca from the NE on the island of Zacate Grande in Honduras. Both Conchagüita and Conchagua are extensively eroded, but a historical eruption was reported from Conchagüita. The NW flank of Isla El Tigre volcano forms the ridge extending into the sea at the extreme left.

Conchagua volcano towers above sandy beaches along the Gulf of Fonseca at the SE tip of El Salvador. The 1225-m-high stratovolcano has a conical profile, but has been extensively eroded. The easternmost of two major summits, Cerro de la Bandera, is seen in this view from Punta el Chiquirín and appears to be younger in age. Recently active fumarolic areas form barren spots on both peaks of this little-studied volcano. Historical reports of eruptions appear to be erroneous, and may refer to landslides associated with earthquakes.

Conchagua volcano has a conical profile when seen from the NE near Punta el Chiriquín. The volcano actually has a much more complex structure than seen here and has been extensively eroded. It has two principal summits. The eastern summit, Cerro de La Bandera, seen in this view, appears morphologically more youthful and is less dissected than Cerro del Ocote, which forms the 1225 m high point of the volcanic complex.

The twin peaks of Volcán Conchagua appear in the distance on the left horizon in this view to the east from the summit of San Miguel volcano. Conchagua lies on the shore of the Gulf of Fonseca at the SE tip of El Salvador. The large lake in the center of the photo is Laguna de Olomega. Flat-topped Cosiqüina volcano in Nicaragua is visible in the far distance at the upper right across the Gulf of Fonseca.
