- The author proposes a method to establish the generalized extreme value model for strong earthquake hazard estimation of a potential source area, based on the maximum information entropy principle and corresponding constraint conditions, and then selects the Ryukyu trench subduction zone as a potential seismic source area for case study. The results show: Considering that the Weibull distribution, among the three kinds of generalized extreme value distribution, has limited upper extreme point, and the upper bound magnitude of a potential seismic source area should be limited, therefore the Weibull distribution model should be selected to establish the generalized extreme value model for strong earthquake hazard estimation; Under the condition that the upper bound magnitude of a potential seismic source area be limited, and in according with the maximum information entropy principle, the probability density function of the maximum magnitude of a potential seismic source area, in each time interval, can be expressed as a general formula with three parameters, and these parameters can be calculated from the estimated values of shape parameter, location parameter and scale parameter of the corresponding Weibull distribution.
