Definition

Ground shaking at a site depends on the earthquake source and mostly on local geological conditions (site amplification effect), which increase or decrease the level of shaking compared with standard energy attenuation, in laterally homogeneous media. To deal properly with local geological conditions, the use of standard attenuation relations may be misleading (Molchan et al. 2011).

Using specific knowledge about geological structures and geotechnical engineering properties described in the published material available for any area of interest, earthquake ground motion scenarios can be computed varying the earthquake source position, mechanism, and magnitude based on advanced physical modeling and minimize the above-mentioned drawback (NDSHA method or Neo-Deterministic Seismic Hazard Assessment), see Panza et al. (2011). The three-component synthetic seismograms, computed, with a broadband content and in laterally inelastic models in the domains of displacement, velocity,...
