Short summary
This study investigated the upper part of a major landslide in the Ecuadorian Andes by combining underground electrical imaging with field geology and sediment observations. The results reveal clear contrasts beneath the slope that are consistent with zones of potential instability, although they cannot confirm a failure surface directly. The work shows that combining geophysical and geological evidence can improve landslide assessment while making uncertainty and data limitations explicit.
