摘要 In this paper,the maximum likelihood estimation of earthquake hazard parameters(β,Mmax)is extended to those data including incomplete and uncertain parts.We calculated earthquake hazard parameters of the Fenwei seismic belt,and the border area between Shaanxi,Sichuan,Hubei and Henan Provinces.The result is comparatively stable and gives an objective evaluation of earthquake hazard.
