A non-parametric approach to site- and soil-specific probabilistic seismic hazard analysis

This study uses the large amount of data acquired during the 2009 L’Aquila and 2016 Amatrice-Norcia seismic sequences in Central Italy to present a novel approach for site-specific seismic hazard assessment. Our approach applies the Generalized Inversion Technique (GIT) to a great number of recordings at several seismic stations, and incorporates the resulting station-specific amplification functions into the conventional procedure for Probabilistic Seismic Hazard Analysis. The scope of work is the definition of a probabilistic hazard map that incorporates site amplification for the site of L’Aquila and surroundings. Results in terms of hazard curves and uniform hazard spectra will be also presented for a couple of sites.
