| 摘 要： | 2000年6月前后，山西中南部出现了6项以流体为代表且具有短临性质的前兆异常。调查结果表明，异常中属人为干扰的有2项，占异常总数的33％，信度较低的异常有1项，占异常总数的17％，反映区域应力场活动的异常有3项，占异常总数的50％。根据以往震例及异常变化特征分析认为，1a内在山西中南部有发生5．0级左右地震的背景。

| Abstract: | The 6 short impending precursor anomalies of the fluid observation have been observed before and after June of 2000 in the centric south area of Shanxi.The investigation shows that 2 terms of them are due to the man made interference,it is 33 % the sum of the anomalies,one anomaly is low creditability,it is 17 % the sum of the anomalies,3 terms of them are due to the regional stress field,it is 50 % the sum of the anomalies.Based on the analysis for the previous examples of earthquake and the variation features of the anomalies,the background of earthquake occurring of about M5 0 exists in the centric south area of Shanxi. |
