Landslide evaluation applying electrical tomography techniques: study case San José de Aloburo, Pimampiro, Imbabura

The present investigation examines a methodology that integrates geophysical and geological methods for the analysis of the displaced mass in the San José de Aloburo landslide, located in the province of Imbabura, Ecuador. Four electrical resistivity tomography (ERT) profiles were used to analyze the internal morphology of the landslide, identifying variations in resistivity associated with different materials and saturation levels. The geophysical data allowed delimiting zones of greater instability and more consolidated areas, providing a basis for identifying the sliding plane of the mass movement. In addition, three stratigraphic columns were carried out at key points in the affected area, which made it possible to describe the arrangement and composition of the strata involved. In addition, a granulometric analysis was carried out on the most representative sample, identifying the particle size distribution and its relationship with the dynamics of the landslide. The results obtained allowed an integral understanding of the landslide, determining that the rupture plane is located between 30 and 40 meters deep in the upper part of the landslide. The methodology used contributes to the understanding of the geologic processes that originated the mass movement, as well as to the evaluation of the slope stability. The result of this research allows validating and integrating this strategy for the study of the evolution of the relief, considering its characteristics both in the subsurface and in the surface.
