Abstract Usually, the definition of geotechnically homogeneous zones is established through the analysis of information on a regional (and even national) scale of those characteristics that define the topographic, geological, climatic, and land use conditions by categorizing them and applying algorithms of interaction between these variables. However, in technical literature and in technical reports of state entities that manage natural hazards, new advances are being made in the determination of other aspects or variables that detail the condition of geotechnical susceptibility; at the same time, nowadays there are technological tools for the massive analysis of information and its spatialization. This article presents a new approach to the definition of geotechnically homogeneous zones using these technological tools. A comparison is made against the conventional definition.
