| 摘 要： | 讨论了华北平原周边１９７５年海城地震，１９３７年荷泽地震及１８３０年磁县地震３次强震的地表地震破裂特征以及这３个地区北西向断裂的全新世活动。研究结果表明，尽管这３次强震地表破裂显示较弱，断续分布，仍反映了存在北西向地表破裂带，活动方式呈左旋走滑兼正倾滑。

| Abstract: | The characteristics of the surface fractures of 1975 Haicheng earthquake,1937 Heze earthquake,1830 Cixian earthquake and activity of Holocene faults in those areas have been discussed in this paper.The results show that there were NW striking seismic ground fracture zones during earthquakes in those areas though they were weak and discontinuous.The style of activity of the fracture zone was mainly sinistral strike slip with normal dip slip.The NW trending Holocene active faults in the areas point recurrent phenomenon of strong earthquakes in the same places.The close relations between the surface fractures of earthquakes and the Holocene active faults shown that the study on the Holocene tectonic activity is more close to study the recent tectonic of strong earthquakes.It also indicates the complexity among shallow tectonic and deep tectonic as well as focal structures. |
