Pastos Grandes Caldera or Cerro Pastos Grandes (a resurgent centre) is an old caldera in the Potosí Department, Bolivia, which belongs to the Altiplano–Puna volcanic complex. Lagunas Pastos Grandes, Khara and Cachi may be remnants of a greater caldera lake. Size of the caldera: 50 km x 40 km. A large (VEI 7) eruption c. 2.9 million years ago produced 820 cubic kilometers (197 cu mi) of tephra.
