Abstract The October 2010 MS4.7 earthquake in the Taikang area is related to the Taikang-Xuchang fault. The Taikang-Xuchang fault, which is in the buried structure and buried active state, has left no structural traces on the surface of the earth. In order to investigate the crustal shallow structure and the spatial distribution and activity of the buried faults in the area, three shallow reflection profiles crossing the buried faults are completed in the epicenter area west of Taikang county in October 2015. The results show that, in depths less than 1 000 meters, the seismic profile reveals five normal faults with obvious fracture features: four north dipping faults located in the south research area, and a south dipping fault, located in the northern research area, and formed opposite inclination in relationship. The profile can distinguish the faults with a depth between 75-150 m, and the fault’s fracture to Quaternary strata in a state of active tectonics. These faults may have a relationship with the Taikang earthquake.
