Spatial distribution of the ensembles of fault models obtained by a the joint inversion, b the GNSS inversion, and c the tsunami-source inversion. The upper panels indicate the spatial distribution of frequency for fault-plane ensembles (color distribution) with the optimal fault model (black frame). The lower panels indicate the selected 40 fault models (gray frame) with the optimal fault model (black frame drawn in purple). The star represents the epicenter. The circles in the upper panels denote the hypocenters of the aftershocks (M ≥ 3) within one day after the mainshock. The gray-colored focal mechanism represents the F-net moment tensor solutions of the 2016 off-Fukushima earthquake. The blue-line beachball represents the focal mechanism of the optimal solution for each inversion
