Abstract. Tropical cyclones are one of the weather phenomena with the biggest threats to human life even in the formative stages of their development because it includes multi-hazards that follow, such as heavy rain, strong wind, lightning, and storm surge. These hazards resulted in disasters such as floods and landslides and caused significant impacts on people, property, and the environment. Rote Island is the southernmost island of Indonesia which is bordered by the southeastern Indian Ocean, Timor Sea, and Arafura Sea, which is a tropical cyclone growth area (cyclogenesis). This study aims to assess cyclogenesis activity in the waters around Rote Island, Nusa Tenggara Timur, and how tropical cyclone activity affects the region. The spatial analysis used to answer the objective of this study with tropical cyclone data activity and disaster events will be used to describe the risk of tropical cyclone activity on Rote Island. The results found how often cyclogenesis activity occurs around Rote Island and the impact is experienced. The conclusion of this result could contribute to the process of mitigating multi-hazard disasters caused by tropical cyclones by decision-makers in Indonesia.
