Data fitting for terrestrial geodetic data with the optimal fault model in a the joint inversion, b the GNSS inversion, c the tsunami-source inversion. The black and red arrows indicate the observed and synthetic static horizontal displacements, respectively. The black star denotes the epicenter. The black frame drawn in purple and the thick black line represent the outline of the optimal fault model and the upper edge of its fault, respectively. The blue arrow indicates the slip vector of the optimal fault model. The circles denote the hypocenters of the aftershocks (M ≥ 3) within one day after the mainshock. d–f Enlarged views of the dotted region in a–c. 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
