Spreading NDSHA application from Italy to other areas

Neo-deterministic seismic hazard assessment (NDSHA) is based on the geophysical and seismotectonic features of a region and adopts a multiscale approach (i.e., regional and local) and multiscenario approach. This methodology has been successfully applied to many regions worldwide and, for the purpose of seismic microzoning, to several urban areas, including lifelines, relevant buildings, and cultural heritage sites. NDSHA naturally supplies realistic time series of ground motion, including reliable estimates of ground displacement readily applicable to seismic isolation techniques, useful to preserve historical monuments and relevant man-made structures. In this way, it creates a viable bridge between the seismological and the engineering community. We discuss here its application to the cities of Rome (where the first seismic microzonation study was developed using NDSHA), Valparaiso (where one of the first multihazard study was developed), and Trieste (where the first NDSHA study for seismic verification was conducted). This contribution should be intended as a sort of an illustrative, but definitely not exhaustive, view in space and time through possible NDSHA applications at a local scale.
