Risk Governance and the Prevention of Sediment Disasters After the 2024 Mw 7.3 Hualien Earthquake in Eastern Taiwan —A Transdisciplinary Approach Case Study

Following a major earthquake, the frequency of debris flows and landslides increases. To effectively mitigate the impact of these disasters and strengthen collaboration and information exchange among the central government, local authorities, and the public, adopting a transdisciplinary approach to disaster risk governance in earthquake-affected areas is crucial. On April 3, 2024, a magnitude 7.3 earthquake struck Hualien, triggering over 1,900 new landslides in eastern Taiwan. The resulting landslide debris poses a significant risk, potentially serving as a source for future debris flows. With the rainy season approaching in May, relevant government agencies responsible for debris flow disaster management have developed comprehensive strategies and actions for prevention, preparedness, response, and recovery phases to address these anticipated hazards.
