This study reviewed the approval and initiation processes and major research contents of China's active fault-related projects, such as the urban active fault survey projects, large-scale mapping programs of active faults, and the earthquake hazard assessment of active faults in key earthquake monitoring and prevention areas. By combining the scientific investigation results of the surface rupture zones induced by strong earthquakes over the past 20 years, this study elaborated on significant advances achieved in the following aspects: the survey and positioning techniques for concealed active faults under strong-noise and weak-signal conditions, the quantitative identification techniques for fault activity, theories and …

Determining setbacks from active faults is the “last 1 km” from active fault surveys to their application to seismic disaster mitigation. It is also a technique for blocking the risk sources of earthquake-induced chains of geologic hazards. Field investigations and experimental studies have demonstrated that buildings and structures can be free from catastrophic destruction caused by coseismic ruptures and offset of active faults provided they are kept at a certain finite distance from the active fault traces. Therefore, determining setbacks from active faults serves as an ultimate goal of the surveys and precise localization of active faults. Based on the …
