Abstract: Landslide is one kind of conventional geologic hazard. It not only causes disaster directly, but also provides material for some kind of hazards such as mud stream and collapse which threat the safety of engieering equipment, life and wealth. On the basis of interpret analysis of remote sensing on landslide hazard, image characteristic of remote sensing on landslide hazard is described through engineering case. Dynamic analysis of landslide is carried out by remote sensing data of multiple source and phase.
