Active tectonic control of a large landslide: Results from Panagopoula landslide multi parametric analyses

摘要

We present the role of active faulting on the landslide activity. In this case,we based our workson a highly active seismic area: the Panagopoula landslide,in the Corinth Gulf (Greece). The approach is basedon the coupling between field investigations and geophysical prospecting by Electrical Resistivity Tomography(ERT). ERT is a powerful method in order to constrain the geological structures in depth and to characterizethe active faults. In our case,it allowed us to show the geometrical relations between high gravity depositsrates,dependant on the slide activity,and the substratum geometry (limestones),recording the fault activity. Ourresults show a high correlation between the fault activity and the slide activity.
