Extended Data Fig. 1

ac, The subduction channel of the seismic cycle model for the southern Andes19. Shown are the stress distribution (a) and the strain rate distribution (b) during the inter-seismic phase of the seismic cycle, 320 years after the great earthquake, as well as a magnified image of the subduction channel (c). Temperature isolines are shown in degrees Celsius, and the location of the maximum shear stress in the channel is given as a proxy for the brittle–ductile transition. d, Sketch of the stress distribution inside the subduction channel, showing the friction-controlled (brittle) and ductile deformation domains.
