地質学的概要

Usulután volcano anchors the SE end of a cluster of basaltic to basaltic andesite stratovolcanoes between San Vicente and San Miguel volcanoes. The flanks of the forested volcano are dissected, but youthful lava flows are present on its southern flanks. The younger summit rocks of Usulután and the Cerro Nanzal pyroclastic cone on the lower SE flank were mapped as Holocene (Weber and Wiesemann, 1978). A broad 1.3-km-wide crater is breached to the E from the summit to its lower flank.
