RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 20, ES5006, doi:10.2205/2020ES000705, 2020 Figure 3. a – Ratios of spectral amplitudes of $S$-waves and coda-waves depending on the hypocentral distance: grey dots – the mixture of data at different frequency bands, black dots indicate the averages within 15-km intervals, and black line is the approximating three-segment function; b – The duration of seismic motions estimated from the records (rhombs) with regard to the hypocentral distance and the duration function used in the simulations (dashed line).
