Herein, “the validity” means that the simulation results of this model do not significantly fluctuate according to different researchers. We introduce the potential of the pseudo-point source model by simulating three crustal earthquakes (i.e., the mid Niigata prefecture earthquake in 2004, the central Chiba prefecture earthquake in 2005, and the northern Nagano prefecture earthquake in 2014) and a plateboundary earthquake (the Tokachi-oki earthquake in 2003) in Japan, using the empirical site amplification. Our calculation results show a good agreement with the waveforms and the Fourier spectra of observations at each earthquake. Therefore, the validity of this model was verified by this study. However, we did not estimate the parameters (e.g., radiation pattern) before the calculations; we used the site amplifications estimated by Nakano et al., which are different from those by Nozu or Hata and Nozu.
