| 摘 要： | IntroductionPaleoearthquake studies belong to the field of active fault study. It has been becoming a significant tool in seismotectonic studies and seismic hazard assessment. On one hand, it prolongsearthquake recording history so that researchers can study seismic recurrent behavior and discussearthquake repeat model in a long time span over several recurrent periods. On the other hand,parameters obtained through paleoearthquake studies are directly used as basic inpUts for seismichazard as…

| Abstract: | Based on detailed studies of paleoearthquakes along major active faults in the transition area between the north eastern margin of Tibetan Plateau and the Ordos block, this paper discusses temporal and spatial distribution of paleoearthquakes and their regional recurrent behavior. The regional paleoarthquake recurrence model in the area exhibits features of temporal and spatial clustering, which may be divided into two kinds. One has a time span about 300 years, and the other has about 1 000 years. |
