【摘要】 在小震调制比方法的基础上提出了探测中强震发生前震源附近调整区位置的一种动态检测法（又称抽时段检测法）。利用已发生的较强地震作为动力源，研究震时和震后一段时间内在一定空间范围内小震调制比的时空响应，响应明显的区（即调制比异常区）可判定为未来震源的调整区。应用组合模式原理，利用两个或两个以上动态异常区得到的交汇区可进行中强震的地点预报。更多还原

【Abstract】 ased on the method of earthquake modulation ratio,a dynamic check method is presented to locate the adjustment area near seismic center before moderate earthquake. Considering moderate earthquake as a dynamic source,we can study the time-spece response of the earthquake modulation ratio during and after earthquake.The region where the response appo distinctly is the area where the earthquake modulation ratio appears abnormally,and can be considered as the adjustment area of future earthquake source. According to the theory of the combination model, the overlap region of two or more dynamic abnormal regions in different periods may be the place where moderate earthquake will occur.更多还原
