Abstract: Active or Concealed faults can form plenty of tectonic physiognomies, controlling the physiognomic difference and was twined by land deformation and water system synchronous turn around, which locate in both sides of the active or concealed fault. In virtue of the characters appearing on the remote sensing image, the active or concealed fault thus can be recognized. The paper focused on displaying the disposal technologies of active and concealed faults in the remote sensing images, and implemented these technologies to process images with different special resolution for the city of Jinan and surronding area. The study can provides the basic data for seismic geology survey and exactly locating the active and concealed faults.
