The aim of this work was to evaluate the landslides risks on the volcano El Pichincha in Ecuador, in estimating the thickness of the conductive layer that may slide. The method used were electrical Schlumberger soundings. The main problem encountered during the interpretation was the topographic effect. A correction had been used that revealed the real apparent resistivity curve and the anisotropy of the site. (Résumé d'auteur)
