Compression at Strike‐Slip Fault Is a Favorable Condition for Subduction Initiation

The recent statistics suggests that over 60% of active Cenozoic subduction initiation (SI) cases are related to the strike-slip fault. A number previous studies have shown lithospheric weak zone is a necessary condition for SI. However, direct effect motion on weakening and SI has rarely been investigated in numerical models due challenge complex 3D boundary conditions. In this study, new model built with both compression results indicate at provides favorable SI, producing maintaining lithospheric-scale facilitates strain localization addition, high velocity buoyant overriding plate contributes young oceanic plate. This mechanism satisfies large natural Cenozoic.
