| 摘 要： | 研究了1992年以来滇西地震预报实验场（24°40’～27°20’N，99°～101°30’E）水汞同步性异常与中强地震的关系。研究结果表明：滇西地震预报实验场水汞同步性异常出现后，滇西实验场区发生M≥5．0地震或滇西实验场邻区（24°～28°N，97°～103°E）发生肘≥6．5强震的概率为75％，平均应震间隔时间为2．7个月，对应效果较好；而且滇西实验场区肘≥5．0地震发生前和滇西实验场邻区M≥6．5强震发生前，滇西实验场水汞同步性异常有很好的反映，概率为83％。

| Abstract: | In this paper, the relationship between synchronous anomalies of mercury from four hot springs and medium-strong earthquakes in Western Yunnan Earthquake Prediction Study Area （WYEPSA） and its adjacent region （24°- 28°N, 97°- 103°E）has been studied. The results show that： Usually, there would be an earthquake of M≥5.0 occurred in WYEPSA or an earthquake of M ≥6.5 occurred in its adjacent region, after a synchronous anomaly of mercury from four hot springs, the corresponding rate could be 75%, the average interval is 2.7 months. And the probability of appearance of synchronous anomalies of mercury before the medium or strong earthquakes in this area is 83%. |
