ABSTRACT In the past decade, passive seismic methods have shown the possibility to detect significant changes in surface wave velocity up to several days prior to landslide failure, even with sensors located outside the unstable zone. Electrical resistivity tomography has also long been used to monitor hydrological changes in landslides....

Dans le cadre du service national d'observation OMIV, des mesures hydro-météorologiques sont réalisées par des stations d'acquisition Campbell CR1000 et Davis Vantage Pro 2.Des logiciels sont fournis par les constructeurs pour configurer les stations, mais leur utilisation pour une récupération automatique à distance des données nécessite leur...

Fluidisation occurring in clay-rich landslides poses serious threats to populations and infrastructures and has been the subject of numerous studies to apprehend its rheological origin. In parallel, noninvasive geophysical techniques on landslides have known considerable development as a means to approach in-situ geotechnical parameters. This...
