Quantitative analysis of rainfall events for potential rapid landslides and flashfloods in brazilian municipalities

Abstract

This study examines rainfall events in Brazil, with emphasis on their potential to induce geo-hydrological hazards, like landslides and flash floods. Utilizing the CHIRPS dataset and rainfall thresholds for landslides, we quantify and analyze climatic hazards at a national level, providing perspective into the relationship between precipitation patterns and geo-hydrological risks. Our findings aim to contribute to a holistic understanding of climatic risk, guiding strategic decisions for disaster risk reduction and climate change adaptation.
