Mexico's volcanoes are part of the Pacific Ring of Fire and formed on the North American continental tectonic plate under which the oceanic Pacific and (in the south) Cocos plates are being subducted.
The most active volcanoes of the country are Popocatepetl, Colima and El Chichon, which had a major eruption in 1982 that cooled the world's climate in the following year.
All active volcanoes of Mexico are listed.
