Amplitude and Mw differences between the JIVSM and F-net 1D model. a Amplitude differences of simulation results from the JIVSM and F-net 1D models. Circle, diamond, inverse triangle, square, and star represent amplitude ratio or station location of N.ASIF, N.TSKF, N,ONSF, N.TTOF, and N.JIZF, respectively. Amplitudes ratios were calculated by dividing maximum amplitudes of simulations using the F-net 1D model by those using the JIVSM. Maximum amplitudes were measured using vertical seismograms for periods of 25–100 s. The relationships between Mw differences and rigidity structures in (b) Kanto and (c) Nankai regions. The rigidity differences were evaluated by differences of the JIVSM rigidities at centroid depths from the F-net 1D model. The Mw differences in (c) was made from the data of Takemura et al. (2020)
