O município de Nova Lima, em Minas Gerais, está localizado em área de grandes elevações altimétricas e declives acentuados. O município compõe a franja sul da Região Metropolitana de Belo Horizonte e, sendo fronteira com a capital, tornou-se território de expressivo valor imobiliário. Por outro lado, Nova Lima integra a região do Quadrilátero ferrífero que destaca-se no cenário nacional pela grande riqueza mineral, especialmente ferro, ouro e manganês. O espraiamento e a verticalização urbana encontram-se lado-a-lado com a mineração, e ambos disputam espaço com elementos de interesse ambiental e de paisagem cultural, o que motiva a melhor compreensão do território e a análise diagnóstica e prognóstica das condições de risco geológico. O Índice de Risco Geológico é apresentado no trabalho como um método aplicável por tecnologias de geoprocessamento que tem como objetivo o subsídio para a tomada de decisões sobre a expansão urbana da região, e pode ser indicado como um modelo de análise espacial aplicável a outros estudos de caso no Brasil, como suporte ao planejamento territorial de áreas caracterizadas por relevo e substrato geológico complexo.
The study area was surrounding Córrego do Feijão Mine, located in the city of Brumadinho/MG, Brazil. From this proposal, we present the analysis of the effect of disruption of one of the tailings dams of the Córrego do Feijão Mine, which took place in January 2019, under the responsibility of Vale S.A. The rupture culminated in mud flow. A study and characterization of the area was made, to understand the flow of the waters, and consequently, the mud. In addition, it was possible to obtain information on the land use of the area before and after the break using remote sensing (Sentinel-2A) supervised image classification. Through a spatial and temporal analysis, it was estimated that the mud reached a total of 2.48 km

, being the class of robust vegetation the most affected by the disaster in numerical terms. The typology of anthropic areas, despite being the smallest area hit by mud, was the one that suffered the greatest impact. The importance of an analysis of the elements that belong in the area of study and how they behave, in order to avoid and mitigate situations of vulnerability is considered very important. Finally, it is emphasized the relevance of a spatial planning studies that considers the integrated planning between the juxtaposition of human activities, social and spatial relations and their various impacts on the landscape.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
