Flatfile of ground motion parameters from HIC (Hybrid Integral Composite) kinematic rupture scenarios in Central Italy

The flat-file collects synthetic ground motion parameters from kinematic rupture scenarios for Central Italy.
The scenarios are generated using the Hybrid Integral Composite (HIC) model by Gallovič and Brokešová (2008) for a hypothetical representative event of Mw 6.2 (Amatrice 2016-like), in a shallow extensional tectonic setting.
The synthetic seismograms are computed in 1D crustal velocity models, including region-specific profiles and creating thousands of rupture scenarios by varying the source parameters, i.e.: i) the fault area, ii) the nucleation point position, iii) the slip distribution, iv) the rupture velocity, and v) the subsource corner frequencies. The resulting distributions of synthetic spectral accelerations, as discussed in Čejka et al (2024), agree with the empirical ground motion model of Sgobba et al. (2021) for Central Italy in terms of the mean and total variability.
