(a) Spatial distribution of frictional parameter γ = a − b for a test model excluded all SAs from original one corresponding to Fig. 1. (b) (c) Snapshots of the slip velocity field for the test model (b) 20 years after and (c) 0.86 year before the occurrence time of the megathrust earthquake, corresponding to Figs. 4 (d) and (e), respectively.
