Tupungatito Volcano is located on the central Chile/Argentina border, 80 km east of Santiago. The volcano consists of 12 craters and a pyroclastic cone. Glacier-filled Nevado Sin Nombre caldera is on the southern side of the volcano.

Eruptions of the volcano are controlled by a north-south fracture system. Andesitic lava flows at Tupungatito have not been eroded. The volcano possibly contains two magma chambers.
