Main image

Usulután is a volcanic massif in eastern El Salvador located in Usulután Department and is one of the department’s prominent topographic features. The volcano forms part of the volcanic chain that runs through El Salvador.

The mountain’s slopes are a mix of natural vegetation and agricultural land typical of the region; it is not one of the country’s most-visited tourist volcanoes but is significant for local geography and land use.

Volcanic activity in the region is part of the Central American volcanic arc formed by subduction of the Cocos Plate beneath the Caribbean Plate; detailed eruption history for this specific cone is not presented here.

The volcano lies inland in eastern El Salvador, within Usulután Department, and is relatively close to the departmental capital of Usulután and to other lowland and coastal areas of the country.
