Jocotitlán is a potentially active volcano, having erupted at least twice in the last 10,000 years.[7] A series of cinder cones lying just north of the Jocotitlán volcano shows how intense the volcanic activity in the region is. If it erupts, the volcano could pose a serious threat to Greater Toluca and even Greater Mexico City.[8]
^As per convention, a summit is considered a peak with at least 500 meters of topographic prominence. Other peaks in Mexico lie higher, but are not prominent enough. For example, mount Tlachichihuatzi has an altitude of 4111 m, but a prominence of only 41 m.[3]
^Isidro Fabela (1882-1964) was a writer and politician native to the region.
