Yogyakarta International Airport (YIA) is strategically located on the coast of Kulon Progo, positioning it within the high-risk zone for tsunamis generated by the subduction zone of the Indo-Australian and Eurasian plates. Given its status as a critical national infrastructure, the operational resilience of YIA against a potential tsunami is paramount for regional economic stability and disaster response logistics. This study aims to analyze the current tsunami disaster mitigation strategies implemented at YIA, focusing on three core areas: (1) Structural and Non-Structural Engineering Measures, (2) Emergency Operational Planning and Protocols, and (3) Integration with Regional Disaster Management Authorities (BPBD). Employing a mixed-methods approach, including a spatial analysis of elevation data, a document review of the Airport Emergency Plan (AEP), and semi-structured expert interviews, the research assesses the adequacy of the existing mitigation framework. Initial findings suggest that while the airport's elevation is designed above the Maximum Credible Tsunami (MCT) inundation line, gaps remain in the rapid evacuation protocols for the landside population and the inter operability of communication systems with external disaster agencies. The study proposes a comprehensive set of recommendations to enhance YIA's operational continuity and resilience against the Tsunami threat
