This project is the prolongation of the on-going FNS project “Rockfall sources: toward accurate frequency estimation and detection” that has shown that rockfall susceptibility can be improved by using other information than the usual discontinuity sets geometry. Rock types, geological contacts geometry, weathering state, water flow paths and thermal conditions are valuable factors to investigate. In order to get this information on high and steep rock faces, this new project proposes to use recent ground based remote sensing techniques. In particular, the focus will be put on coupling terrestrial laser scanning with multispectral and thermal imaging. For rockfall susceptibility assessment, these investigations will help to better define rock release locations, thermal stress deformation, preferential erosion zones, water flow paths, event frequencies and erosion rates. This approach is not limited to rockfall assessment but of primary interest for vertical geology, i.e. the geological mapping of rock properties on high resolution 3D surfaces. Vertical geology will maximize the information extracted from steep rock walls, in order to use it as input data for 3D geological mapping and modeling.Several sites have been selected according to the different stages and goals of the project. Research works in the Yosemite Valley will continue with the vertical geology approach in order to improve the rockfall hazard mapping. There, a specific emphasize will be put on quantifying effects of thermal variation on rock deformation and rupture by coupling thermal imaging with lidar data. A new field of investigation will start in Torres del Paine (Chile) to get 3D geological maps of igneous intrusion bodies in high vertical walls. Other sites in the Alps and in France, with active rockfalls and excellent outcrop conditions, will be investigated to produce full 3D geological models.
