Photogrammetry technique is applied to landslide behaviour monitoring and underground slide surface analysis in this paper. The landslide behaviour information necessary to measure of disaster reduction and prevention can be obtained speedily, correctly and safely by this technique. Three dimensional displacement of ground objects such as rocks, trees, farms and various artificial structures can be traced by photogrammetries taken at different recording chance. Analyzing these data, moving direction and velocity of sliding block is distinguished. Depth and shape of the underground slide surface can be presumed by least square method. Accordingly, warning region of the landslide is demarcated on a map.This paper demonstrates utility of the photogrammetry applied to observation and analysis of landslide occurred in Hirose district in Nagano city.
