Rupture Process of the 2020 Caribbean Earthquake along the Oriente Transform Fault, Involving Supershear Rupture and Geometric Complexity of Fault

Abstract

We built a kinematic source model of the 2020 Caribbean earthquake to analyze the spatiotemporal evolution of fault geometry and slip • A fault bend disturbed supershear rupture along the linear fault section and triggered subsequent rupture • Oceanic transform faults can have geometric complexity that controls rupture evolution
