Co- and post-seismic slip distributions for the dip–slip case. a, e The synthetic co- and post-seismic slip distributions given for the dip–slip case of the synthetic tests, respectively. b, f The estimated co- and post-seismic slip distributions in the elastic model, respectively. c, g The estimated co- and post-seismic slip distributions in the viscoelastic model, respectively. d, h Respectively show the co- and post-seismic slip distributions estimated in the viscoelastic model constraining negative postseismic slip. Gray triangles show the site distributions during the corresponding period. Each small gray arrow in the upper panels represents direction of coseismic slip in a sub-fault. The direction of postseismic slip is fixed to orthogonal direction to the trench
