Serdán-Oriental volcano is a young volcanic field forming a closed basin at the eastern end of the Mexican Altiplano. It contains tuff rings and lake-filled maars (such as Laguna Atexcac and Laguna Alchichica), cinder cones, lava domes and lava flows.
The date last volcanic activity is unknown, but occurred less than 10,000 years ago. A major explosive eruption from a now probably buried vent produced the Quetzalapa plinian pumice-fall deposit 20,000 years ago.
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
