摘要
通过对江苏地区5 次中强以上地震前应变, 形变临震前兆异常的分析,结果表明, 震前异常形态表现为应力应变值出现大幅度突跳、应变阶跃和固体潮畸变等, 与5 级以上地震对应较好,
In this paper,the strain and deformation anomalies feature of impending earthquake with five moderate and strong shock occurred in Jiangsu area are analyzed.The results show that the anomalous variation before earthquakes appears as:large amplitude catastrophic jump of stress and strain, strain step,and solid tide distortion,ete. which are corresponding to the earthquakes with M ≥5 0 very well. The results will be considered in short-impending prediction of moderate and strong earthquakes in Jiangsu area.
