| Zusammenfassung |
| 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. |
