Xitle

Xitle (ʃitɬe Nahuatl, "navel") is a monogenetic volcano in the Ajusco range in Cumbres del Ajusco National Park. It is located in the Tlalpan borough in the southwestern part of Mexico City. It is an ash cone volcano with a conical form, round base, altitude of approximately 300m, and a slope between 30° and 40°. Xitle erupted during the period AD 245-315, according to the results of radiocarbon dating. Among the consequences of this eruption were the formation of the Pedregal de San Ángel lava fields, to the south of the Mexican Federal District. Cuicuilco, one of the most refined cities of Mesoamerica, was destroyed and covered by lava. The subsequent diaspora of the Cuicuilcans, and the attendant diffusion of their culture across most of central Mexico, influenced important cultural changes in the nearby power center of Teotihuacan. According to some other sources, a series of big volcano eruptions, and the destruction of Cuicuilco took place in the 1st century BC.

Nahuatl
Nahuatl (ˈnɑːwɑːtəl ; ˈnaːwat͡ɬ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about 1.7 million Nahua peoples, most of whom live mainly in Central Mexico and have smaller populations in the United States. Nahuatl has been spoken in central Mexico since at least the seventh century CE. It was the language of the Aztec/Mexica, who dominated what is now central Mexico during the Late Postclassic period of Mesoamerican history.
Cuicuilco
Cuicuilco is an important archaeological site located on the southern shore of Lake Texcoco in the southeastern Valley of Mexico, in what is today the borough of Tlalpan in Mexico City. Some historians believe this settlement goes back to 1400 BC. Other historians believe the pyramid could be the oldest building in the Americas circa 6,500 BC. Cuicuilco flourished during the Mesoamerican Middle and Late Formative (c. 700 BCE – 150 CE) periods.
Tlalpan
Tlalpan (, ˈtɬaːɬpan̥) is a borough (demarcación territorial) in Mexico City. It is the largest borough, with over eighty percent under conservation as forest and other ecologically sensitive area. The rest, almost all of it on the northern edge, has been urban since the mid-20th century. When it was created in 1928, it was named after the most important settlement of the area, Tlalpan, which is referred to as “Tlalpan center” (Tlalpan centro) to distinguish it from the borough.
