Abstract: The electrical resistivity tomography survey was conducted to detect the active faults along the Tanlu fault zone in Weifang,Shandong province.The results of 2-D resistivity inversion of the Yishui-Tangtou and the Liujazhuang faults indicate that electrical structures on both sides of the fault zone present obvious difference,the resistivity of the hanging wall is low and partially high,while that of the foot wall is high,and the faults are high-obliquity faults.Results show that the resistivity tomography survey is very effective for detection of active faults in urban area.

Key words: Tanlu fault zone, resistivity tomography survey, active faults, inversion
