Understanding the physics of earthquakes is one of the current grand challenges of Earth
science. Earthquake rupture is a complex process that involves multiple coupled phenomena
and occurs at depths that cannot be probed directly. Computer simulations of dynamic
rupture are an essential tool for basic research in earthquake science and applied research
in earthquake hazard. Computational earthquake dynamics involves physics-based modeling
of fault slip, seismic wave propagation and the resulting ground motions, and is enabled by
advanced numerical algorithms and high-performance computing.br> |

Final report:
During this BaCaTeC research project, we have studied the effects of 3D fault zones on dynamic earthquake ruptures and high-frequency ground motion by using the software SeisSol. Our successful collaboration included two research visits and a short course on recent developments in the field of earthquake dynamics. Furthermore, it led to a publication entitled “Pulse-like rupture induced by three-dimensional fault zone flower structures” in the Journal of Pure and Applied Geophysics and a presentation at the EGU 2013 General Assembly in Vienna, Austria [1,2]. | |
