| Abstract: | The intensification and frequency of natural hazards pose significant challenges to human societies, requiring an improved understanding of hazards and risks for enhanced disaster risk assessment. Hazards often interact in complex ways, particularly during multi-hazard events like tropical cyclones (TCs). This study focuses on understanding multi-hazard interactions during TC Maria (2017) in Dominica, Caribbean Islands, which involved high winds, storm surges, and landslides, leading to significant socio-economic impacts. TC Maria exemplifies the cascading nature of multi-hazards, where one hazard can trigger subsequent in a chain reaction of events, exacerbating damage. The study aims to analyse these interactions and their effects on structures, emphasizing the importance of recognizing multi-hazard dynamics for accurate risk assessment. Study's findings highlight the intricate interactions between wind, storm surge, and landslide processes during TC Maria, revealing the significant role of wind in triggering subsequent hazards. High winds caused structural damage directly and indirectly, through mechanisms like flying debris and tree falls, which further influenced flood and landslide occurrences. The affected regions exhibited compounded damage due to these interactions, emphasizing the need for multi-hazard-focused risk assessments. By attempting to analyze multi-hazard interactions, this study contributes to a more nuanced understanding of disaster risks, facilitating better resource allocation and emergency planning. The integration of CFD wind modelling approaches, such as CityFFD, offers valuable insights into localized hazard impacts, supporting efforts to build resilient communities against future multi-hazard events. |
