Variation of the predicted Fourier spectrum at KUMA for the mainshock. (Left) Pink lines indicate the synthetic Fourier spectra of cases that showed better average FS errors than the reference case. The red line indicates the geometric mean of pink lines. The blue line indicates the synthetic Fourier spectrum of the reference case. The black line indicates the observed Fourier spectrum. (Upper right) Pink, red, and blue lines indicate the spectral ratios of the corresponding lines in the left panel to the observed spectrum. (Bottom right) Black lines indicate the ranges of FS error at each site
