【摘要】 中国东部,相对来说东南沿海地区的地震活动较为频繁,断裂构造也十分发育。地震活动与断裂构造有非常密切的关系,震中与断裂构造的空间分布也关系密切。通过对东南沿海大量震例的调查和研究,分析三组断裂与地震的关系,得出东南沿海地区东西向、北东向和北西向的三组断裂构造,分别构成了区内的衰减构造、控震构造和发震构造,形成了东南沿海陆缘构造活动带。更多还原

【Abstract】 In the southeast coastal region of China,seismicity is of high frequency,and fracture structure is abundantly existent.There is a close relation between seismicity and fracture structure,between epicenter and the spatial distribution of fracture structure.The transmeridional,northeast-striking and northwest-striking faults are respectively considered as’attenuation structure’,’earthquake-controlling structure’and’Seismogenic structure’by investigating and studying the earthquake examples on the three sets of faults and their relationship with earthquakes.They formed the active epicontinental fracture zone in the southeast coastal region.更多还原
