Summary The goal of this work is to expand understanding of the physical settings in which system-wide earthquakes can occur through the use of large-scale, physically-robust earthquake cycle models. To do this a large scale, high-performance framework that accounts for complex fault geometries, off-fault material properties, and full dynamics in 3D volumes. The method will couple interseismic loading with coseismic rupture and wave propagation in a self-consistent manner. The coupled approach will be used to explore how tectonic loading, rupture history, fault geometry and other physical features play a role in system-wide failure of fault networks. This will include such studies as the keystone fault hypothesis, namely, that faults in the system that are optimally oriented with respect to the regional stress field are stabilized by a misoriented keystone fault until the entire network is primed to fail.
