ABSTRACT This manuscript presents a review on the application of remote sensing technique (terrestrial laser scanning, TLS) to well‐known topic (rock slope characterization and monitoring). Although number publications use TLS in rock studies has rapidly increased last 5–10 years, little effort been made key developments, establish code best practice unify future research approaches. The acquisition dense 3D terrain information with high accuracy, data speed increasingly efficient...

Abstract. Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characterization and monitoring. Landslide rockfall movements can be detected by means comparison sequential scans. One pressing challenges natural hazards combined temporal spatial prediction rockfall. An outdoor experiment was performed to ascertain whether TLS instrumental error small enough enable detection precursory displacements millimetric magnitude. This consists a known...

Abstract. Terrestrial laser scanning (TLS) provides high-resolution point clouds of the topography and new TLS instruments with ranges exceeding 300 m or even 1000 are powerful tools for characterizing monitoring slope movements. This study focuses on 35 million m3 Åknes rockslide in Western Norway, which is one most investigated monitored rockslides world. The used structural analysis steep, inaccessible main scarp rockslide, including an assessment discontinuity sets fold axes....

For more than 10 years, digital elevation models (DEM) produced by light detection and ranging (LIDAR) technology have provided new tools for geomorphologic studies especially landslide studies. In particular, terrestrial laser scanning (TLS) provides a great versatility of use. TLS can be used either monitoring purposes or in an emergency situation that necessitates rapid DEM acquisition assessing hazard. Using three examples we demonstrate the usefulness volume quantification, profile...

The basal sliding surfaces in large rockslides are often composed of several and possess a complex geometry. exact morphology location three dimensions the surface remains generally unknown, spite extensive field subsurface investigations, such as those at Åknes rockslide (western Norway). This knowledge is crucial for volume estimations, failure mechanisms, numerical slope stability modeling. paper focuses on geomorphologic characterization postglacial scar vicinity Åknes. displays stepped...

Abstract Åknes is an active complex large rockslide of approximately 30–40 Mm 3 located within the Proterozoic gneisses western Norway. The observed surface displacements indicate that this divided into several blocks moving in different directions at velocities between and 10 cm year −1 . Because regional safety issues economic interests has been extensively monitored since 2004. understanding deformation mechanism crucial for implementation a viable monitoring system. Detailed field...

We present a classification system for hazard and risk that is posed by unstable rock slopes in Norway might undergo catastrophic failure future can cause loss of life. The scenario-based as the intensity rate displacement, well geological structures activated sliding mass vary significantly on slopes. In addition, each scenario secondary effects, such genera- tion displacement waves or landslide damming valleys with potential later outburst floods, are evaluated. analysis based two types...

Abstract Displacement waves (or tsunamis) generated by sub-aerial landslides cause damage along shorelines over long distances, making run-up assessment a crucial component of landslide risk analysis. Although site-specific modelling provides important insight into the behaviour potential waves, more general approaches using limited input parameters are necessary for preliminary assessments. We use catalogue landslide-generated displacement to develop semi-empirical relationships linking...
