The Binchuan Basin is located in the western part of Yunnan Province, China. It is driven by the Chenghai Fault in the “Dianxibei” rift belt which has large number of active faults and high seismicity. The loose sediments of the basin can aggravate the damage of earthquakes by an amplification effect (Tape et al. 2017). The populated Binchuan basin is covered by thick sediments, and seismic hazards are a great concern. Therefore, the detection of the detailed distribution of sedimentary layers is highly necessary.
