A series of youthful lava flows was erupted from vents cutting through Tertiary pyroclastic rocks WNW of Ipala volcano about 5 km S of the town of Quezaltepeque. These basaltic flows issued passively from vents along a N-S-trending fault without accompanying explosive activity. The vents are capped by low mounds of lava. The flows were considered to be of Holocene age by Williams et al. (1964).
The right side of the relatively cloud-free area at the center of this NASA Landsat image (with north to top) contains the Quezaltepeque volcanic field. A series of youthful lava flows was erupted from vents along a N-S-trending fault cutting through Tertiary pyroclastic rocks about 5 km south of the town of Quezaltepeque. The northern end of Lake Güija along the Guatemala/El Salvador border is at the bottom of the image, and the city of Chiquimula is at the top center. The fault-controlled Río Motagua valley is at the upper left.
