REASSESS

(05.26.2017) REASSESS V2.0 (beta) HAS BEEN RELEASED:REASSESS software is a stand-alone user-friendly software for the probabilistic assessment of seismic hazard. REASSESS V 2.0 performs (i) site-specific and (ii) multi-site seismic hazard analysis. For (i) it computes hazard curves, uniform hazard spectra, disaggregation and conditional mean spectra at a specific site. For (ii) it computes the probability of observing any given number of joint exceedances of a ground motion intensity measure at a set of sites in a given time interval, the total number of exceedances at multiple locations in any time interval, and the number of sites experiencing at least one exceedance in a given time interval. Seismic sources can be either zones or individual faults. REASSESS also is able to account for model uncertainty, in fact, logic trees can be built based on alternatives for the source's annual rate of earthquake occurrence, magnitude distribution and ground motion prediction equation. Finally REASSESS allow to perform sequence-based probabilistic seismic hazard analysis; i.e., hazard analysis including aftershocks.
