Evolution of the Sedrun landslide (Graubünden, Switzerland) with ortho-rectified air images
Abstract The slope movement at Sedrun (Switzerland) has been studied with ortho-rectified images. Displacement maps compiled for two periods (1973–1990 and 1990–2003), based on a correlation of the aerial images indicate maximum average slope movements of 60 cm/year, similar to those obtained by traditional photogrammetry over the period 1973–1990. The limits of the most active zones determined by image correlation correspond to those obtained by fieldwork. Comparison of the two displacement maps shows an acceleration of the instability of 150% since 1990. This paper demonstrates the value of using more than one technique to help understand the evolution of this long-term instability.
