Table 1: Details of the two subsets of ground motion data deepened for the study based on the NGA—West 2 database. Figure 1: Elastic response spectra of the (**a**) near-fault and (**b**) far-field subset of records. The figures highlight the two records of the 2016 Norcia Earthquake, \(\overline{S_{a}}\) is the average response spectra from the two set, and \(\overline{S_{a}}\pm\sigma\) is the range of variance according to standard deviation. (**c**) Normal distribution of \(S_{a}\) for \(T=T_{1}\). Figure 2: M\({}_{w}\) magnitude–R\({}_{\rm jb}\) distance scatter diagrams of the two subsets, Sel. 1 NF and Sel. 7 FF.
