The fresh-looking lava flows at the top of the image were erupted from Los Humeros caldera (just out of view to the north). The basaltic and andesitic lava flows extend up to about 15 km from the caldera rim. The flows have not been dated precisely, but are younger than 20,000 years and could in part be of Holocene age. The Tepeyahualco (left) and Limón (right) lava flows bracket circular 3100-m-high Cerro Pizarro lava dome (right center), the northernmost feature of the Serdán-Oriental volcanic field.
