Highly simplified geological map of the Puyehue–Cordón Caulle volcanic complex, redrawn from Singer et al.24 and Lara et al.25 The Cordón Caulle volcanic system forms a 20-km-long and 4-km-wide ridge oriented NW-SE. The main fault scarps associated with the 1960 eruption25 are shown. Scale bar, 5 km in length. Inset: map indicating position of Cordón Caulle volcanic complex in southern Chile, redrawn from ref. 30. Scale bar, 100 km in length.
