Geophysical and Seismic Noise Investigations of a Clayey Earthflow

B006 Geophysical and seismic noise investigations of a clayey earthflow Summary 1 The Super-Sauze earthflow (South Alps Fig. 1) is a clayey flow-like landslide characterized by a complex vertical structure associating a slip surface and a viscoplastic plug. In order to evaluate the probability of the earthflow to mobilize into a debris flow it appears of primary interest to image and characterize its internal structure. These purposes are difficult to achieve due to the rough topography of the site and to contrasted variations of the mechanical hydrological and geometrical characteristics. The aim of this study is to evaluate the potential
