“…Furthermore, the 3‐D basin imaging allows us to define the infill geometry and thickness changes; this is crucial for scenario‐based seismic hazard analyses, because wave reverberation and local ground‐motion amplification are primarily controlled by sharp seismic velocity contrasts, geometric complexities in the buried bedrock topography, and lithological properties of the sedimentary infill [ Bard and Bouchon , ; Aki , ; De Luca et al ., ; Hartzell et al ., ; among many others]. In fact, increased duration, frequency‐dependent ground‐motion amplification, and spatial variability of ground motions have been observed frequently in both the near‐ and far‐field of strong to great earthquakes.…”
