Large-scale earthquake dynamic rupture simulations can improve earthquake ground motion estimates by generating predictions of earthquake behavior under controllable and realistic conditions. We study the effect of natural fault zone parametrization (e.g. geometry and initial stress distribution) on the dynamics of earthquake sources and the resulting seismic hazard assessment. We employ LMU’s SeisSol software, a high-order Discontinuous Galerkin Finite Element solver for seismic wave propagation on unstructured meshes, and SORD (developed at USC), a generalized finite-difference code for simulating spontaneous rupture within a 3D isotropic viscoelastic media, in a HPC environment.
