The view of the 1870 vent and the San Pedro-Ceboruco graben is from the Ceboruco summit. The small lava dome to the lower right and the unvegetated lava flow to the lower left were emplaced during the 1870-75 eruption. The Cerro San Pedro lava dome on the horizon directly above the 1870 dome was constructed within the 7 x 10 km San Pedro caldera. The peak immediately left of Cerro San Pedro is Cerro Tetillas.
