The summit lava dome complex of Tecuamburro is seen here from the NE along the road from Cuilapa. Four adjacent NW-SE-trending lava domes, the SE-most (left-center) of which is Tecuamburro proper, were erupted within a large horseshoe-shaped scar left by collapse of an ancestral edifice. These domes erupted less than 38,000 years ago. The Tecuamburro complex was constructed within a 20-km-wide graben whose northern margin terminates against the major regional Jalpatagua fault.
