Popocatépetl in the context of Pico de Orizaba

Volcanoes in Mexico form a significant part of the country's geological landscape, with numerous active and extinct volcanoes primarily located along the central-southern Trans-Mexican Volcanic Belt. The diverse array of volcanic features in Mexico includes stratovolcanoes, shield volcanoes, cinder cones, lava domes, and calderas.

Many of Mexico's volcanoes are part of the Pacific Ring of Fire, a region characterized by frequent earthquakes and volcanic eruptions. Notable volcanoes include Popocatépetl, one of the country's most active and dangerous volcanoes, Pico de Orizaba (Citlaltépetl), the highest peak in Mexico, and Parícutin, a cinder cone volcano that famously emerged from a cornfield in 1943.Volcanoes play a significant role in Mexico's geography, climate, and culture, influencing local ecosystems, agriculture, and human settlements. The volcanic activity also poses hazards to surrounding communities, necessitating ongoing monitoring and disaster preparedness efforts.

Chalcatzingo is a Mesoamerican archaeological site in the Valley of Morelos (municipality of Jantetelco) dating from the Formative Period of Mesoamerican chronology. The site is well known for its extensive array of Olmec-style monumental art and iconography. Located in the southern portion of the Central Highlands of Mexico, Chalcatzingo is estimated to have been settled as early as 1500 BCE. The inhabitants began to produce and display Olmec-style art and architecture around 900 BCE. At its height between 700 BCE and 500 BCE, Chalcatzingo's population is estimated at between five hundred and a thousand people. By 500 BCE it had gone into decline. The climate in Morelos is generally warmer and more humid than the rest of the Highlands. The Chalcatzingo center covers roughly 100 acres (0.40 km). Evidence indicates that this was a site of ritual significance.

Chalcatzingo is situated near two large granodiorite hills in the Amatzinac River Valley, within an otherwise generally flat landscape. Its early residents likely sourced their water from a nearby spring.
