“…The main sets of structural features have been identified in several rockslides in Norway (Derron et al 2005). This approach also allowed a fast structural characterization of the hardly accessible Mount Steele rockslide in Yukon, Canada (Brideau et al 2009) and the reinterpretation of former rockslide such as Frank slide (Sturzenegger et al 2007a;Froese et al 2009). At regional scale, the fjord valley of Tafjord in Norway has been investigated in order to characterize the present and former rock slope instabilities, such as their volume and mechanisms (Oppikofer 2009).…”

This paper presents a short history of the appraisal of laser scanner technologies in geosciences used for imaging relief by high-resolution digital elevation models (HRDEMs) or 3D models. A general overview of light detection and ranging (LIDAR) techniques applied to landslides is given, followed by a review of different applications of LIDAR for landslide, rockfall and debris-flow. These applications are classified as: (1) Detection and characterization of mass movements; (2) Hazard assessment and susceptibility mapping; (3) Modelling; (4) Monitoring. This review emphasizes how LIDARderived HRDEMs can be used to investigate any type of landslides. It is clear that such HRDEMs are not yet a common tool for landslides investigations, but this technique has opened new domains of applications that still have to be developed.

“…Such a resolution will result in the truncation of medium to high persistence discontinuities. In contrast, with a sub-horizontal line-of-sight, a terrestrial 3-D model provides a higher ground resolution on sub-vertical slopes (up to 40 mm for TLS and 96 mm for TDP with an f =400 mm lens), Preliminary observations using terrestrial and airborne LiDAR on Turtle Mountain were presented in a previous paper by the authors (Sturzenegger et al, 2007b).…”

“…Conventional field-based mapping, using intrusive and non-intrusive methods have been applied (Cruden and Krahn, 1973;Fossey, 1986;Couture, 1998;Spratt and Lamb, 2005;Theune et al, 2005;Langenberg et al, 2006). Airborne remote-sensing techniques, including SAR and InSAR methods (Singhroy and Molch, 2004;Singhroy et al, 2005;Mei et al, 2008), photogrammetry (Jaboyedoff et al, 2009) and LiDAR (Sturzenegger et al, 2007b) have been used to monitor motion or characterize both the mountain and the morphology of the debris. The structure and geology of Turtle Mountain has been described by Cruden and Krahn (1973) and further detailed by Langenberg et al (2006).…”

Abstract. This paper describes experience gained in the application of terrestrial digital photogrammetry and terrestrial laser scanning for the characterization of the structure of high mountain rock slopes and large landslides. A methodology allowing the creation and registration of 3-D models with limited access to high mountain rock slopes is developed and its accuracy verified. The importance of occlusion, ground resolution, scale and reflectivity are discussed. Special emphasis is given to the concept of observation scale and resulting scale bias and its influence on discontinuity characterization. The step-path geometry of persistent composite surfaces and its role in remote sensing measurements are described. An example of combined terrestrial digital photogrammetry and terrestrial laser scanning applied in the generation of a 3-D model of the South Peak of Turtle Mountain, the location of the Frank Slide, is presented. The advantages gained from the combined use of these techniques and the potential offered through long-range terrestrial digital photogrammetry, using high focal length lenses up to 400 mm is illustrated. Special emphasis is given to the potential of this specific technique, which has to the authors knowledge rarely been documented in the geotechnical literature.

“…Others researchers have undertaken more specific analyses of the joint sets based on field survey (Couture 1998), as well as borehole logging analysis and ground penetrating radar (GPR) (Spratt & Lamb 2005) in the South Peak area. Recent studies (Sturzenegger et al 2007;Froese et al 2009b;Jaboyedoff et al 2009;Sturzenegger & Stead 2009) provide a structural analysis based on remote-sensing datasets such as airborne laser scanning (ALS), terrestrial laser scanning (TLS) and the derived digital elevation model (DEM).…”

Structural analysis of Turtle Mountain: origin and influence of fractures in the development of rock slope failures

Large slope failures in fractured rocks are often controlled by the combination of pre-existing tectonic fracturing and brittle failure propagation in the intact rock mass during the pre-failure phase. This study focuses on the influence of fold-related fractures and of postfolding fractures on slope instabilities with emphasis on Turtle Mountain, located in SW Alberta (Canada). The structural features of Turtle Mountain, especially to the south of the 1903 Frank Slide, were investigated using a high-resolution digital elevation model combined with a detailed field survey. These investigations allowed the identification of six main discontinuity sets influencing the slope instability and surface morphology. According to the different deformation phases affecting the area, the potential origin of the detected fractures was assessed. Three discontinuity sets are correlated with the folding phase and the others with post-folding movements. In order to characterize the rock mass quality in the different portions of the Turtle Mountain anticline, the geological strength index (GSI) has been estimated. The GSI results show a decrease in rock mass quality approaching the fold hinge area due to higher fracture persistence and higher weathering. These observations allow us to propose a model for the potential failure mechanisms related to fold structures.
