Santiago, Cerro (Guatemala)

Status Unknown Eruption Unknown 1192m
Volcanic field (Subduction zone / Continental crust (> 25 km))

A cluster of cinder cones and low shield volcanoes surrounds the city of Jutiapa in SE Guatemala. The most prominent feature is Cerro Santiago, one of two coalescing cinder cones capping a low shield volcano SE of the city. Youthful flows from the twin 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 by Williams et al., 1964 as Volcano Amayo), a craterless cinder cone surrounded by basaltic lava flows. It is one of several cinder cones to have produced lava flows that blanket the landscape between Jutiapa and Tertiary volcanic hills to the S.

A cluster of cinder cones and low shield volcanoes surrounds the city of Jutiapa in SE Guatemala. This photo shows Volcán Culma, a lava cone composed of coarsely porphyritic basaltic lavas on the eastern side of the city. The most prominent feature of the volcanic field is Cerro Santiago, one of two coalescing cinder cones capping a low shield volcano SE of Jutiapa. This photo was taken from the Pan-American highway, which here is underlain by youthful flows from the twin Los Cerritos cones NE of Jutiapa.
