Geoelectrical Characterization of Sedimentary Landslides in the Laguna Del Amor Area, Chota-Cajamarca (Peru)
Source abstract
Abstract
This study focuses on the geometric and geophysical characterization of sedimentary landslides in the Laguna del Amor area, located in Chota-Cajamarca (Peru). The main objective was to identify key static factors related to landslide susceptibility, including slope angle, soil composition, and groundwater flow, prioritizing the areas affected by landslides. Electrical Resistivity Tomography (ERT) was the geophysical method selected because of its effectiveness in delineating subsurface geometries, detecting water content, and assessing mass movements. The methodology combined geophysical analysis (ERT), field geology, and photogrammetry to develop a detailed subsurface model. The results indicate a rotational landslide mainly composed of weathered shales and limestones, with highly saturated zones that increase the area’s hazard level. The investigation also identified significant variability in landslide depth throughout the study area, highlighting the importance of these factors in geotechnical risk assessment. This interdisciplinary approach not only contributes to geological knowledge of the area but also provides critical information for mitigation and risk management strategies in landslide-prone areas.
