摘要
运用地震活动度(S)的计算模型对1983年菏泽5.9级地震前后,周围地区进行了时空扫描,发现了在主震前2-3年的时空分布上,S值都有一个异常升高的过程。
In this paper,the epicentral and around area before and after the Heze earthquake (M=5.9)of 1983 have been scanned in time-space by the computing model of seismicity function S,the anomalous high level of S in time-space distribution have been before main earthquake about two years appeared.
