The San Diego volcanic field is an extensive volcanic field on the El Salvador–Guatemala border of Central America. It consists of a group of basaltic cinder cones and lava flows, with the largest feature being Volcán de San Diego after which the volcanic field is named.[1]
Volcanism in the San Diego volcanic field took place north and east of Lake Güija which is dammed by a large basaltic lava flow from Volcán de San Diego. The volcanic field remains undated but may have been active within the last few thousand years.[1]
