Geologic risks are associated to the different processes inherited by the dynamic condition of the natural environment. Often, these processes have reached a natural state of equilibrium or stability. Nevertheless, in some instances human activity interferes with the natural order, modifying the existing equilibrium or balance state. Such is the example of some geologic rock outcrops, originally generated under pressure and temperature conditions, different from the ones found at the surface of the earth. These outcrops, when subjected to surface atmospheric conditions experience a sudden release of large forces associated to the potential energy accumulated over long periods of time (thousands to millions of years). The goal of this study is to focus on the anthropogenic disequilibrium induced over a segment of the Sierra de Juarez, consequence of the removal of large rock masses in the construction of a scenic point (Mirador Hidalgo) and a traversing highway (Camino Real). The applied methodology consisted in the integration through a Geographic Information System (GIS) of high-resolution topographic maps, terrain analysis, geologic mapping, electric resistivity tomography and time domain electromagnetic soundings as a mean to evaluate the potential hazard that the Mirador Hidalgo represents in terms of an arbitrary Geologic Susceptibility Index (GSI). Based on the obtained results, a series of immediate actions are proposed, which are to be considered in order to avoid continuing damage to the highway infrastructure as well as the potential loss of human lives.
