Fourier spectra estimated for the blind prediction Step 3 for the mainshock. The Fourier spectra estimated for the blind prediction Step 3 for the mainshock (red traces) are compared with the Fourier spectra calculated from the recorded acceleration waveforms distributed after the blind prediction (black traces). The Fourier spectra are smoothed with a Parzen window of 0.05 Hz
