Quarries are large wells or depressions in the land resulting from deep extractive activities. When these activities end, most of them are abandoned, representing a potential and/ or permanent threat to the health and physical integrity of the population. Starting from recognizing the complexity of the territory and the multidimensionality of the problem, this article proposes to develop a methodology to assess their danger, taking La Plata County as the case study. The methodology consists of two moments: a first moment of survey and identification of all the quarries present in the case study and a second moment of diagnosis, where a matrix is built to determine the hazard degree. In this way, the study intends to construct an tool for analysis that can be replicated in other regions where extractive activities are carried out, in order to prevent and mitigate their impact.
