Adaptations made to the geodetically inferred fault geometry to develop a realistic dynamic rupture model. Changes made to the fault geometry are highlighted by plotting the here used geometry over the fault geometry of Xu et al.7 shown in transparent blue. The distribution of initial fault stress ratio R (Eq. 10) along the fault network is also shown. The spatial distribution of parameters defining the stress (SHmax, R, and zseis defined in “Initial stresses” in Methods section) are indicated. The magnitude of the initial stress loading is decreased in the Needle fault region to prevent large slip on this optimally oriented segment (such a decrease is modeled by decreasing R0 by 60% and suppressing the deep stress concentrations in that region)
