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
