Abstract To discuss the rapid identification of active faults using airborne LiDAR technology, the Tieluzi fault, which borders Weihe basin and Qinling mountains in Guanzhong, is taken as the practice object. After accurate extraction of topographic point cloud data, we give a 2 m resolution DEM, and construct the geometric distribution characteristics of the scanning area. The test results show that the method based on the high-resolution DEM data and the interpretation of fault characteristic troughs and triangles are helpful to improve the accuracy of the airborne LiDAR technology in the rapid identification of active faults in complex terrain. The airborne LiDAR provides a strong technical support for the rapid detection of active faults.
