The methods to evaluate fault activity must be applicable to many kind of faults in the basement terrain, in the case of important engineering problem such as the aseismic design of nuclear power plant. In this paper, the authors gave reviewed some problems which have been discussed about the activity of faults, from both scientific and engineering viewpoints home and abroad. Some characteristic features of faults have been shown through many data of dams and nuclear sites, such as fault length, distribution density, fracture thickness, texture and materials in fracture zone. Some typical methods, applicable to various kind of actual faults both inland and seabottom, are presented through the recent studies on fault activity evaluation. In conclusion, the authors have proposed a proper evaluating system of fault activity evaluation. In conclusion, the authors have proposed a proper evaluating system of fault activity for nuclear power plant, considering the scientific and technical development and the rule required to aseismic design in the present.
