The Neo-Deterministic Seismic Hazard Assessment (NDSHA) procedure for the development of seismic hazard maps at the regional scale has been validated by all the events occurred in regions where NDSHA maps were available at the time of the quake. NDSHA method reliably and realistically simulates the wide suite of earthquake ground motions that may impact civil populations as well as their heritage buildings. The scenario based NDSHA’s modeling technique is developed from comprehensive physical knowledge of: (i) the seismic source process; (ii) the propagation of earthquake waves; and (iii) their combined interactions with site effects. A useful safety factor conceptually similar to the ones used in structural engineering can be used to set the estimated magnitude of the scenario events. Using the signals generated by NDSHA, well rooted on the fundamental laws of physics and on the experimental evidence, a number of possible structural engineering approaches become available.
