A051 SHALLOW SURFACE-WAVE DISPERSION APPLIED TO THE STUDY OF LANDSLIDES: AN EXAMPLE IN THE JURA MOUNTAINS WESTERN SWITZERLAND. Introduction 1 In Switzerland landslides represent a major geologic hazard. Each year landslides cause damages that affect civil engineering structures and have important financial consequences. Thorough understanding of failure type sliding mechanism and cause of landslides is required to effectively mitigate their impact. Typically studies of landslides and slope instabilities make use of geotechnical hydrological and GIS monitoring techniques. Geophysical surveys can help better understand landslides by providing information about their internal structure and seismic refraction profiling and electrical resistivity surveys have
