摘要

对1970年以来华北北部及东北地区(37°—55°N,103°—135°E,除甘肃、宁夏和境外朝鲜)的36次Ms 5以上中强地震前空区和条带图像扫描分析,着重讨沦研究区不同类型地震(大主震、中强主震和晚期强余震)与空区、条带关系,主震与空区、条带持续时间关系,主震与空区、条带空间尺度及围空、条带起算震级等统计关系,一定程度上表明,震前空区、条带异常图像是研究区强震发生的重要异常判据。
The seismicity gap and band patterns in the north of North China and Northeast China region (37°—55°N,103°—135°E,in addition Gansu,Ningxia and outside Korea)with the same procedure from a relatively complete catalogue of 36 M_S 5 moderate and strong earthquake since 1970 are analyzed.Based on the above,we discuss the statistic relation between the different types of earthquake(strong earthquake,moderate and strong earthquake and Late strong aftershock)and gap and band patterns,the main-shock and the lasting time of the gap and the band,the scale of the gap and the band,the earthquake magnitude forming gaps and band in the study region.The result shows that gap and band patterns are important exception criterion before strong earthquake in the study region.
