Fig. 1: Some steps of the modeled intraoceanic subduction process, tracking the evolution of a new outer-rise faults network (reference model).

a A main and antithetic serpentinized faults form in the oceanic lithosphere close to the trench. b The fault network enters the subduction zone and evolves in a graben-like structure. c–f Outer-rise faults are progressively buried at increasing depths while other faults develop at the surface. The lithologies are represented with different colors, as described in Supplementary Fig. 6. The red box highlights the evolution of the new fault network formed at the outer rise. White lines are isotherms (°C); “t” is the time after subduction begins. Here the main fault develops along a pre-existing fault.
