In urban karst environments, land subsidence is a geological hazard often associated with urban damage. In these types of landforms, subsidence occurs naturally and mainly associated with human interventions. It is triggered by the dissolution of the substrate with the subsequent sink of the terrain, forming features commonly called dolines or sinkholes. Located in the central area of the Minas Gerais state, Curvelo's town is situated geologically on the southeastern edge of the São Francisco Craton. In this region, recent sedimentary clusters out cover outcropping proterozoic metasedimentary rocks. The Bambuí group, with metapelitic rocks from the Serra de Santa Helena formation and the carbonate rocks of the Sete Lagoas and Lagoa do Jacaré formations, represents the most expressive stratigraphic unit. As a result of this limestone substrate, landforms related to karst dissolution, such as caves and dolines, occurs in the region. In 2019, Curvelo was affected by the subsidence of the land generating large cracks in nearby houses and in the asphalt leaving six families unable to return to their homes. Under this geomorphological context, a different approach is necessary to guide the urbanization of the town, considering its particularity. With a less expensive method this work seeks to delimitate areas that are likely to trigger these phenomena as a way of contributing to territorial ordering, preventing property losses to public authorities. This work uses geological and geophysical data of the area of Curvelo and its surroundings to show regions more favorable to outbreak a land sinking process. This work uses pre-mapped geological data and geophysical surveys of magnetometry, radiometry and electrical methods, to determine different georeferenced classes of influence. This analysis made it possible to regionally characterize geophysical facies and lineaments, which integrated with the use and occupation maps, determine areas suitable for geotechnical problems, and, in a more detailed scale, confirm the presence of cavities through geoelectric surveys. Therefore, maps of potential for deflagration were made based on geological and geophysical analyzes. Integrated in GIS base the analyzed data presented categorized zones of susceptibility to the outbreak of subsidence, as well as made it possible to define the typology of subsidence in the region. Information that helps the management of geological risk areas in the municipality.
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.
