b-value of the Gutenberg-Richter law is known as a critical parameter in seismic hazard analysis and prediction. b-value is considered as random variable because it is obtained through regression analysis based on available seismic data. Considering the probability distribution of b-value can yields more accurate hazard curves. In this paper, Gutenberg-Richter relation is revised and then applied to PSHA. So, calculating b-value variance, based on bootstrap sampling of the seismic catalog, we attempt to develop a systematic numerical approach for the b-value uncertainty application in probabilistic seismic hazard analysis using normal distribution. This approach illustrates the effects of b-value fluctuations on hazard curve. So considering parameter uncertainty in hazard computations we can reduce epistemic uncertainty and give more rational hazard estimates.
