The State of Rio de Janeiro enchants everyone by the beauty and landscape diversity, because it is possible to be close to the Serra and the Sea, however the sudden drop of relief works as a physical bulkhead for the entrance of cold fronts coming from the Atlantic Ocean, which culminate in the formation of heavy rains. Such conditions, added to geology, geomorphology, population density, the constructive profile of buildings, socio-environmental vulnerability and anthropic actions, can trigger mass movements with great destructive power. The increase in recurrences and concentration of rainfall has been increasingly catastrophic, requiring the adoption of technical and management measures that are increasingly fast and effective. In April 2022, the state of Rio de Janeiro faced a serious disaster in the south of the state, being decreed an Emergency Situation in the municipality of Angra dos Reis (Decree 12553/2022 of 02/04/2022).
