Seismic risk maps for the seismic risk management and reduction

Abstract

The paper illustrates the seismic risk maps computed by the Authors for the residential building stock of Italy by using a general framework specifically set up for mapping seismic risk for a generic asset of interest. Seismic risk maps are computed taking into account a seismogenic model of the analyzed area, and properly characterizing vulnerability and exposure of an asset of interest. Seismic risks maps are computed for two different conditions, the former represents the so-called as-built condition, the latter one is computed assuming for the residential building stock a possible strategic retrofit program. These two maps are then used for investigating the financial sustainability of national seismic risk reduction programs, focusing the attention on the specific case of the national residential building stock of Italy.
