a Coulomb failure stress change (ΔCFS) due to the three foreshocks, b initial shear stress, and c initial normal stress on a non-planar fault used in dynamic rupture simulations of the main shock. The initial stresses are the sum of the static stress changes due to the three foreshocks and the regional stress field for \(\sigma_{1} = 100\;{\text{MPa}}\) and \(\sigma_{3} = 50\;{\text{MPa}}\). The stars indicate the epicenter of the main shock obtained by Yoshida et al. (2016)
