Seismic Zoning Methods That Assume Spatially Non-Uniform Earthquake Distribution in the Potential Source:Their Application to Western Panzhihua and Central and Southern Shanxi Province

摘要

Based on the models of non-uniform earthquake distribution in the potential source,the seismic zonation of Western Panzhihua and Central and Southern Shanxi Province is studied.The results show that the usual uniform distribution model may underestimate the seismic risk and result in a reduction of the areas of high intensity.The influence of each non-uniform probabilistic distribution method on the result of seismic zoning is discussed.
