英文摘要	The Northern Zhongtiaoshan Fault is a major deep fault at the southern margin of the Yuncheng Basin. There have been few studies on the fault, and the historical earthquakes are few and weak. However, the intensity of activity on the fault should never be underestimated. Through interpretations of aerial images, topography measurements and excavation of trenches, this paper studied the fault distribution, the surface deformation and the activity of the normal fault south of Salt Lake near the city of Yuncheng. By tracing faults in the three trenches, it was found that there had been at least three large paleoseismic events, at 1-3.5, 3.6-4.4 and 7.4-8.8 ka BP. Employing C-14 dating, we determined the same gravel layers in the uplifted side and downthrown side. Making differential Global Positioning System measurements of the vertical difference and topographic profile, we obtained the mean slip rate of the Northern Zhongtiaoshan Fault since 24.7 ka BP (0.75 +/- 0.05 mm/a). Using the results of relevant studies, we calculated the possible vertical fault displacement of one earthquake (2.35 m) and obtained the recurrence interval of characteristic earthquakes as 2940-3360 a after dividing the displacement by the mean slip rate.; Geosciences, Multidisciplinary; SCI(E); EI; 1; ARTICLE; ssp002@163.com; 9; 2079-2088; 57
