| 摘 要： | 通过对地震、 地质和地球物理等资料的分析, 发现华北平原西北部于三河、 涞水、 灵寿一线存在一条地震构造带。 该地震构造带在华北地区公元1000年以来的第三地震活跃期内地震活动最为强烈, 记有8级地震1次, 6级多地震3次和数次5级左右的地震。 这条地震构造带斜穿渤海湾盆地内早第三纪形成的大兴隆起和冀中、 北京等坳陷, 是一条晚第三纪以来新发育的构造带。 此带的发现使华北平原的地震构造格局更加完善。

| Abstract: | We put forward a new seismotectonic zone along Sanhe, Laishui and Lingshou in the northwest of the North China Plan based on seismological, geological and geophysical data. Many earthquakes have occurred along the zone, such as Sanhe earthquake with magnitude 8 in 1679, Tongxian 61/2 in 1665 and 6 in 1536, Laishui 6 in 1658 and several 5~5.9 earthquakes. This seismotectonic zone across Daxing upheaval, Jizhong and Beijing depression, is a newly generated seismotectonic zone since Later Tertiary. The seismicity along the seismotectonic zone was intense in the third seismic period in North China, but has been quiet in the fourth seismic period until now. The discovery made the seismotectonic framework in the North China Plain more perfect. |
