| 摘 要： | 系统研究了江苏及邻区１９７０年以来较有影响的９次中强震前地震空区、中小地震条带分布等地震活动图象异常变化特征，认为江苏及邻区地震前出现地震条带、地震空区等异常现象较普遍。在本地区研究条带异常所选取的震级下限为ＭＬ３０为宜，在黄海地区研究地震空区震级下限取为ＭＬ３０，而陆地地震空区可取ＭＬ２０为震级下限。

| Abstract: | The anomalous variety characteristics of seismicity pattern such as seismic gap and stripe have been studied before 9 important moderate earthquakes of Jiangsu and adjacent area since 1970 It is general that the seismic gaps and stripes appear in this region before earthquakes In the study low limit magnitude of seismic stripe was took as M L3 0, and those in the Yellow Sea and land gaps are M L3 0 and 2 0, respectively |
