Abstract

We present results of thorough benchmarking of an arbitrary high-order derivative discontinuous Galerkin (ADER-DG) method on unstructured meshes for advanced earthquake dynamic rupture problems. We verify the method by comparison to well-established numerical methods in a series of verification exercises, including dipping and branching fault geometries, heterogeneous initial conditions, bimaterial interfaces and several rate-and-state friction laws. We show that the combination of meshing flexibility and high-order accuracy of the ADER-DG method makes it a competitive tool to study earthquake dynamics in geometrically complicated setups.

Alice-Agnes Gabriel was funded by the Deutsche Forschungsgemeinschaft (KA 4-1) and Jean-Paul Ampuero by the US NSF (CAREER award EAR-1151926) and SCEC (based on NSF Cooperative Agreement EAR-0529922 and USGS Cooperative Agreement 07HQAC0026). BaCaTeC supported research visits for Jean-Paul Ampuero and Christian Pelties at LMU and Caltech, respectively. The computations were performed on SuperMUC at LRZ, Garching, Germany, and Shaheen at KAUST, Saudi Arabia. Edited by: L. Gross
