The Neo-Deterministic Seismic Hazard Assessment (NDSHA) has been applied for nearly three decades to evaluate seismic hazard at both regional and local scales in Italy and internationally. At the local scale, NDSHA is able to integrate geological, seismotectonic, and geotechnical data to generate ground motion scenarios, broadband time histories, and related damage indicators, which serve as input for engineering design. Furthermore, NDSHA is a comprehensive approach to assess the local seismic response (LSR) to be used in microzonation studies. Hereinafter, the NDSHA-based analysis of LSR along a 2D section at the Chieti site (Italy) will be illustrated. While results are broadly consistent with traditional 2D finite element method, NDSHA offers additional insight into subsurface wave field behavior within the simulated domain.
