Resumo: In several Brazilian cities, the phenomenon of urbanization was developed in an accelerated, intense, and unplanned manner, leading to the occupation of areas unsuitable for housing, such as steep slopes and soils with little stability. In addition to other consequences, this occupation regime, combined with adverse weather conditions, favors the occurrence of mass movements, causing property and environmental damage, in addition to the loss of human life. Therefore, this study aimed to map the areas susceptible to mass movements in the Tejipió river basin, in Pernambuco, due to the physical-natural characteristics and the significant urbanization rate presented in the region. The methodology was based on the integration, in a Geographic Information System (GIS) environment, of factors conditioning this type of process, namely: geology, geomorphology, pedology, land cover and use, slope, and rainfall. Then, weights were assigned to these factors, regarding the degree of potential for mass movements, so that the final product resulted in a thematic map of susceptibility to the aforementioned process. The main results revealed that 24.65 km² of the basin is represented by areas highly susceptible to mass movements, which is equivalent to 28.10% of the region and presents a combination of associated factors such as high hypsometry and slope and clayey soils. The mapping developed in this study comprises an important tool that aims to support planning and risk management for geological phenomena, allowing the definition of effective measures to prevent, protect, and mitigate negative impacts caused by mass movements.

Además de otras consecuencias, este régimen de ocupación, combinado con condiciones climáticas adversas, favorece la ocurrencia de movimientos masivos, provocando daños materiales y ambientales, además de la pérdida de vidas humanas. Por lo tanto, este estudio tuvo como objetivo mapear las áreas susceptibles a movimientos en masa en la cuenca del río Tejipió, en Pernambuco, debido a las características físico-naturales y al importante índice de urbanización que presenta la región. La metodología utilizada se basó en la integración, en un entorno de Sistema de Información Geográfica (SIG), de factores que condicionan este tipo de procesos, a saber: geología, geomorfología, edafología, cobertura y uso del suelo, pendiente y precipitaciones. Luego, se asignaron pesos a estos factores, en función del grado de potencial de movimientos de masas, de modo que el producto final resultó en un mapa temático de susceptibilidad al proceso antes mencionado. Los principales resultados revelaron que 24,65 km² de la región están representados por áreas altamente susceptibles a movimientos en masa, lo que equivale al 28,10% del territorio, que presenta una combinación de factores asociados como alta hipsometría y suelos de pendiente y arcillosos. El mapeo desarrollado en este estudio constituye una importante herramienta que tiene como objetivo apoyar la planificación y gestión de riesgos de fenómenos geológicos, permitiendo definir medidas efectivas para prevenir, proteger y mitigar los impactos negativos causados por los movimientos en masa.Em diversas cidades brasileiras, o fenômeno da urbanização foi desenvolvido de maneira acelerada, intensa e não planejada, levando à ocupação de áreas inadequadas à habitação, como encostas declivosas e com solos de pouca estabilidade. Além de outras consequências, esse regime de ocupação, somado às condições climáticas adversas, favorecem a ocorrência de movimentos de massas, provocando danos patrimoniais e ambientais, além perdas de vidas humanas. Dessa forma, este estudo teve por objetivo mapear as áreas suscetíveis a movimentos de massa na bacia hidrográfica do rio Tejipió, em Pernambuco, devido às características físico-naturais e ao significativo índice de urbanização apresentados na região. A metodologia utilizada fundamentou-se na integração, em ambiente de Sistema de Informações Geográficas (SIG), de fatores condicionantes a esse tipo de processo, sendo eles: geologia, geomorfologia, pedologia, cobertura e uso da terra, declividade e pluviosidade. Em seguida, foram atribuídos pesos a estes fatores, quanto ao grau de potencialidade a movimentos de massa, de modo que o produto final resultou em um mapa temático de suscetibilidade ao supracitado processo. Os principais resultados revelaram que 24,65 km² da bacia é representada por áreas altamente suscetíveis aos movimentos de massa, o que equivale a 28,10% da região, as quais apresentam uma combinação de fatores associados como elevadas hipsometria e declividade e solos argilosos. O mapeamento desenvolvido neste estudo compreende uma importante ferramenta que visa subsidiar o planejamento e a gestão do risco a fenômenos geológicos, permitindo a definição de medidas eficazes à prevenção, proteção e mitigação dos impactos negativos causados por movimentos de massa.Universidade do Estado do Rio Grande do Norte (UERN)2024-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion Peer reviewed Revisado por paresAvaliado pelos paresapplication/pdfapplication/pdfhttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/543310.33237/2236-255X.2024.5433Journal Geotemas; Vol. 14 (2024): Geotemas Journal; e02404Revista Geotemas; Vol. 14 (2024): Revista Geotemas; e02404Revista Geotemas; v. 14 (2024): Revista Geotemas; e024042236-255Xreponame:Revista Geotemasinstname:Universidade do Estado do Rio Grande do Norte (UERN)instacron:UERNporenghttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/5433/4202https://periodicos.apps.uern.br/index.php/GEOTemas/article/view/5433/4201Copyright (c) 2024 Revista Geotemashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPessoa Neto, Amaury GouveiaSilva, Simone Rosa daLafayette, Kalinny Patrícia VazBarbosa, Ioná Maria Beltrão Rameh2024-04-17T13:13:54Zoai:ojs2.periodicos.apps.uern.br:article/5433Revistahttp://periodicos.apps.uern.br/index.php/GEOTemas/indexPUBhttp://periodicos.apps.uern.br/index.php/GEOTemas/oaigeotemas@uern.br||josielguedes@yahoo.com.br2236-255X2236-255Xopendoar:2024-04-17T13:13:54Revista Geotemas - Universidade do Estado do Rio Grande do Norte (UERN)false
