Abstract: The contents and related methods for near-field seismotectonic studies during nuclear power plant siting, including the investigation of geological structures, the tectonic activity, and active faults, the studies on deeper geophysical characteristics, and the definition of seismogenic structures, are discussed in this paper. Some important topics, such as determination of fault activity, deep structural environment, and seismogenic structures, are revealed in detail.
