Usulután volcano rises above the Pacific coastal plain at the SE end of a cluster of stratovolcanoes between San Vicente and San Miguel volcanoes.  The forested Usulután volcano is mostly dissected, but youthful lava flows are present on its southern flanks, and the volcano was mapped in part as Holocene in age.  Several large erosional craters cut the flanks of Usulután, including the valley seen in this view cutting the SW flank.  The rounded peak at the left is the young cone of Cerro Oromontique on the margin of El Tigre volcano. Photo by Lee Siebert, 1999 (Smithsonian Institution).
