Santiago, Cerro Volcano — Guatemala

A cluster of cinder cones and low shield volcanoes surrounds the city of Jutiapa in SE Guatemala. The most prominent is Cerro Santiago, one of two coalescing cinder cones capping a shield SE of the city. Youthful flows from the two Los Cerritos cones NE of Jutiapa cross the Interamerican Highway. Volcán Culma forms a steep-sided basaltic lava mound immediately E of the city. To the W lies Cerro Gordo (referred to as Amayo by Williams et al., 1964), a craterless cinder cone surrounded by basaltic lava flows. It is one of several cinder cones to have produced lava flows that cover the area between Jutiapa and Tertiary volcanic hills to the S.
