The 2011-2013 Swiss National Foundation projects Understanding landslide precursory deformation from superficial 3D data FNS 138015 and Characterizing and analyzing 3D temporal slope evolution FNS 144040 (follow up of the previous one) have recently finished. Both projects, which were leaded by Michel Jaboyedoff and I was co-applicant, have allowed me to carried out extensive research for my post-doc. As already commented here, the projects were based on the development of new algorithmsaiming to properly describe in detail complex mass movements evolution in 4D. We remarkably developed a series of new algorithms aiming to quantify 3D deformation along time (object tracking), automatic rockfalls extraction, noise filtering, and analysis of the influence of external parameters on time-variant landslides… we then applied these algorithms for a better understanding of the role of precursory landslides leading to larger failures. Such as output of our research, I include a non-exhaustive list with publications and conference proceedings I have collaborated with during the project (I’m still updating the complete list, conference presentations not included yet and some in preparation manuscripts, we will present our scientific report soon):
