This paper mainly discusses the precise positioning method for the urban seismic mobile moving fault, and the study results shows: the frequency sweeping method and the mutual correlation method of data processing can effectively suppress the disturbances from strong vibrations with the vibroseis in the strong-disturbance background in the city so as to carry out the seismic investigations in the urban area; for the sliding faults in which there is no clear fault displacements between the two beds, the high-resolution seismic prospecting method and electrical prospecting method can be used to position the fault precisely; finally, a case is used to demonstrate the precision positioning method based on the electrical prospecting.
