Abstract—The main objective of this paper is to show GPR (Ground Penetrating Radar) applicable method for active and siesmogenic fault exploration in urban area. The case study has done on north Shahre Ray fault in south of Tehran (Iran). The north Shahre Ray fault on base of exist data is reported as main earthquake sources in Tehran and Ray city. GPR method has applied in three points of active north Ray fault with 100 and 200 MHz frequency antennas in Azim abad village and around. The two points had selected on soil and one on the asphalt where three point locations were on fault along approximately. Field observation of GPR method testing on fault consists of three simple and compound profiles. The compound profile interpretation results shows that fault plan and Tectonic anomaly sharply. The case study conclusions suggest that GPR method is useful and quick tool in compare with other methods for active fault exploration in urban area with average deep fault.
