Joint inversion results. a The slip distribution model obtained by the joint inversion of GNSS and OBP data. The gray circles indicate aftershocks (catalog of ISC and JMA) occurring within one week after the mainshock. b Comparison of GNSS static offsets between observations (black color) and synthetic results (red color). The gray contours indicate the total vertical displacement computed using the joint inversion result. The light gray line and the dark gray line represent 0.1 m and 0.5 m intervals, respectively. c Comparisons of tsunami waveforms between observations (black) and synthetic results (red) at four OBPs
