Abstract Seismic methods are main tool of imvestigating deep buried active faults. Applications of seismic method are restricted seriously due to complex of shallow seismic geological conditions and frequency of artificial activity in the city. It is favorable for suppressing strong background noise and improving S/N ratio and resolution of seismic record when high frequency geophones and phase correlating stacking techniques as well as some other techniques at suitable working time are used during field data acquisition. We can obtain high quality seismic section when proper data processing techniques are used at data processing stage.
