This study explores risk communication and institutional reform dilemmas in compound disasters, focusing on the September 23, 2025, Mataian Creek landslide-dammed lake overflow in Hualien. Originating from geological destabilization caused by the magnitude 7.2 Hualien earthquake on April 3, 2024, typhoon-induced massive landslides formed a dammed lake that ultimately overflowed during torrential rains. Encompassing seismic activity, slope failure, and flooding, this compound disaster's complexity far exceeds Taiwan's current single-hazard-oriented disaster management framework. Grounded in Comprehensive Emergency Management and Disaster Risk Management frameworks, this study utilizes literature and secondary data analyses to cross-compare normative deficiencies and practical execution within central and local government disaster management plans. Findings highlight four primary institutional deficiencies: lacking SOPs for compound disaster chain drills; excluding landslide-dammed lake overflows from statutory disasters, causing jurisdictional ambiguity; frequent risk assessment fluctuations that undermine public trust in early warnings; and insufficient frontline personnel, resulting in an "emphasis on resettlement over preparedness." Implementation challenges further reveal that Cell Broadcast Service (CBS) alerts have limited efficacy among elderly indigenous populations; "vertical evacuation" protocols sparked controversy due to inadequate prior assessment and public education; and spontaneous volunteers caused logistical disruptions owing to insufficient regulatory frameworks. Future research will incorporate in-depth stakeholder interviews to elucidate the discrepancies between institutional design and practical execution, aiming to propose actionable policy recommendations for refining compound disaster governance in Taiwan.
