| 摘 要： | 本文介绍了京津唐地区内埋藏在全新世地层中的一次古地震遗迹和构造变形。通过对本区全新世地层、古环境的研究确定这次地震事件为距今4000年、本区海侵结束时发生的,恰恰与史料纪载的“地震传说”一致。文章最后对发震背景,砂基液化以及震中、震级等问题进行了一些讨论

| Abstract: | The traces and tectonic deformations of palaeoearthquake event hurried in Holocene strata in Beijing-Tianjin-Tangshan area have been studied in this paper. The study of Holocene strata and palaeo-environment suggests that the event occurred in the time when Holocene transgression ended in North China and coincided with a legend of disaster in ancient time 4000 years ago. Some phenomena related to this palaeo-earthquake have been discussed in this paper,such as seismic tectonic background, liquifaction of sandy basic in the strata, epicentre and magnitude of this event |
