  1. GM indicates the total moment tensor inferred from our slip distributions. SM shows the seismic moment tensor of the main shock (M w 7.0). The decomposition of SM into normal faulting and strike-slip faulting was derived by the eigenvalues of the moment tensor (dip–strike = 1.32:3.40). The total SM is derived by (σ 1 − σ 3)/2, where σ 1 and σ 3 are the maximum and the minimum eigenvalues, respectively
