Abstract:The mode of fault movement and slip rate are important parameters for studying fault activity and determining earthquake risk. Based on processing and reconstruction of cross fault leveling observation data accumulated over the years in the Shanxi fault depression zone,we analyzed the current movement characteristics of the main faults in each structural area based on structural zoning. The results suggest that the main faults in the Shanxi fault depression zone were mainly characterized by inherited normal fault movement during the observation period,and there were significant differences in fault movement characteristics among different basins. The vertical activity of the north and south sections was significantly greater than that of the middle section,in which the Xinding Basin is of the smallest cumulative change value. From the perspective of vertical activity rate of faults,the activity rate of Mount Wutai Fault,Shizhoushan piedmont fault,Tanghe fault and Huoshan piedmont fault across faults is significantly lower than that of the whole region. Due to long-term tectonic stress loading and the influence of moderate to strong earthquakes in the region,there are also differences in fault movements at different time periods. Some cross fault survey sections,such as Xiaxiazhi,Tingzhitou,Taiyuan,and Guangshengsi,exhibit significant features such as reverse fault inheritance movement and relative fault locking.
