摘要
采用几种方法分析了大同地震后华北地区的地震形势。根据地震活动和构造特征划分了研究区域，用作者提出的灰色线性预测模型及可公度性预测了发震时间，用作者提出的多点测位法预测了地震危险区并用近百年大陆地震活动特征估计了震级。综合分析结果认为，１９９５～１９９６年华北发生ＭＳ≥５．５地震的概率为Ｐｔ｛１９９５～１９６６｝＝７／１１～８／１１，地震危险区位于晋东南的概率为ＰＳ＝７／８～１。
Seismic situation in North China after the Datong M 6.1 earthquake is analysed by using several kinds of methods.It is considered that probability for M s≥5.5 event to occur in the region during 1995 and 1996 is from 7/11 to 8/11 and probability to occur in southeast Shanxi Province is from 7/8 to 1.
