Volcanic activity in the area occurred between 15 and 10 million years ago, and Cerro San Antonio, a heavily eroded 3 million years old Miocene volcano with a westward-opening collapse scar, lies just north of Uturuncu. Other volcanoes from east counterclockwise to west are the Cerro Panizos caldera, Cerro Lípez, Suni K'ira and Quetena volcanoes as well as many more minor volcanic centres. Many of them are formed along northwest-southeast trending lineaments such as the Lipez-Coranzuli and Pastos Grandes-Cojina lineament that passes through Uturuncu.
