| 英文摘要 | This study aims at providing the spatial contours of frequency-content parameters of ground motion records obtained during the 2017 Mw 7.3 Ezgeleh–Kermanshah earthquake in Iran. For this purpose, three scalar frequency-content parameters named the mean period (Tm) , the average spectral period (Tave) , and the smoothed spectral predominant period (T) are calculated. Sixty earthquake records with the closest site-to-source distances in the range of 5–330 km were used to make several high-resolution frequency-content maps for the study area. In addition, a new practical framework is presented to estimate soil condition maps based on a simplified ground motion records analyzing which could be used in rapid loss evaluation after earthquakes. As a new idea, the main features of the horizontal-to-vertical spectral ratio curves including amplification amplitude and peak frequency that can identify resonance effect are automatically considered in the proposed regional soil class map. The consistency between frequency-content maps with the anticipated soil condition map is discussed. Prepared maps showed that very long period range extends in the northwest–southeast direction, far from the epicenter. © 2020, Springer Nature B.V. |
