Abstract To study the shallow tectonic characteristics of Linying fault, we complete two high-resolution seismic reflection profiles across the fault. Based on the obtained seismic reflection profiles, combined with petroleum seismic profiles and regional geological data, we analyze the location, shallow tectonic features, and activity of Linying buried fault. The results show that Linying fault is a normal fault with an overall northwest strike and northeast dip. The latest active age is early Pleistocene. A secondary fault is developed in hanging wall of the fault, forming an inverted “Y” shape with the main fault. The research results can provide seismology basis for seismic risk assessment, urban planning, and land use in Xuchang city and its adjacent areas.
