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，1 a内在山西中南部有发生5.0级左右地震的背景。
2000年6月前後，山西中南部齣現瞭6項以流體為代錶且具有短臨性質的前兆異常。調查結果錶明，異常中屬人為榦擾的有2項，佔異常總數的33 %，信度較低的異常有1項，佔異常總數的17 %，反映區域應力場活動的異常有3項，佔異常總數的50 %。根據以往震例及異常變化特徵分析認為，1 a內在山西中南部有髮生5.0級左右地震的揹景。

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.
