Amplitude ratio of synthetic records between that for the original finite fault model (U. S. Geological Survey 2020) and that with a time-stretched source time function of \(f(t/r_t)/r_t\), where t denotes time, f(t) the original source time function, and \(r_t\) temporal stretching ratio (shown on the horizontal axis). The amplitude was evaluated at Urahoro station for the 2003 Tokachi-oki earthquake. Three types of amplitudes are shown, highpass filtered displacement (200-s cutoff, solid line); highpass filtered integrated displacement (200-s cutoff, dashed line); bandpass-filtered displacement (200-400 s, long-dashed line)
