考虑近期中小地震的地震危险性分析──以山西南部和四川西部地区为例

Seismic Risk Analysis With Consideration of Recent Mid-Small Earthquake──Taking Southern Part of Shanxi Province and Western Part of Sichuan Province for Example

以四川酉部和山西南部为例，根据现有多种地震目录的不同精度，确定不同的震级下限，依据最大似然模型，求得由不同资料得到的各潜在震源区的地震活动性参数，并依据通用的地震危险性分析模型，得到了这两个区域的地震烈度区划图。

Based on different magnitude threshold by different catalogues with different precisions, the seismicity parameters of various potential seismic areas have been obtained by maximun likelihod model. with different seismic data. According to general seismic risk analysis model, the seismic zoning maps for the southern part of Shanxi Province and the western part of Sichuan Province have been shown.
