Acknowledgements: We thank the Southern California Earthquake Center, especially Ruth Harris and Michael Barall, for hosting the Spontaneous Rupture Code Verification Project, Yoshihiro Kaneko for helpful discussions on the implementation of rate-and-state friction and Amaryllis Nerger for her preparatory work on the 2-D version of the branching fault benchmark. Christian Pelties was funded through the Emmy Noether Programme (KA 2281/2-1) of the Deutsche Forschungsgemeinschaft and by the Volkswagen Stiftung (ASCETE project). 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.

N2 - 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.
