Due to the population growth and expansion of urban structures, it is an essential to identify hidden and unknown faults in cities for sustainable development before the construction of some important structures (e.g., residential towers, hospitals, subway tunnels, energy transmission lines such as water, electricity, gas, Telecommunications and also large commercial, military centers, etc.). There are different geophysical methods for identifying hidden faults or fault with clear escarpments. Recently, the use of ambient seismic noise has been used widely due to its advantages no disturbance of conventional seismic methods and no damage to the environment. Therefore, we designed a northward seismic array with inter-station distances of ~70 m and 3 km length to collect raw data. This array intersects the hidden and probable Pardisan fault within Tehran city. Prior to extract field data, the synthetic modeling was performed to calculate the quality and uncertainty resulting from the designed array.
