Statistical distributions for probabilistic seismic hazard analysis
Keywords:
seismic hazard, PSHA, binomial, geometric exponential and Poisson distributions, Poisson process, return periodAbstract
The study of statistical distributions in the context of probabilistic seismic hazard analysis (PSHA) provides a convenient support for understanding and application of PSHA specific procedures. This approach also provides a useful insight on relevant aspects of probability theory with application to seismic hazard. The geometric, exponential, binomial and Poisson distributions along with their proofs are introduced within the seismic hazard framework. These distributions represent the main tools for handling probabilistic hazard data as they are essential for assessing the probability of exceedance of the hazard parameter within a certain exposure period of structural system.
