Behavioral Economics of Disaster Risk Perception: Underestimating Flood Risks During a Non-Landfalling Tropical Cyclone and Acceptance of AI-Based Weather Forecasting in the Philippines' Typhoon Landfall Region

This supplementary file contains the complete research instruments, analytical framework, coding procedures, and extended statistical results for the study entitled Behavioral Economics of Disaster Risk Perception: Underestimating Flood Risks During a Non-Landfalling Tropical Cyclone and Acceptance of AI-Based Weather Forecasting in the Philippines’ Typhoon Landfall Region. The document includes bilingual (English and Filipino) informed consent forms and survey questionnaires, Likert coding tables, econometric model specifications, variable construction, STATA and R analytical codes, and comprehensive descriptive and regression outputs. It further presents detailed analyses of flood risk perception, preparedness behavior, disaster risk communication, perception–reality gaps, and trust in AI-based weather forecasting during Tropical Storm Ada (Nokaen) in Camarines Sur, Philippines. The supplementary material is intended to support transparency, reproducibility, methodological validation, and future replication of the study by providing complete technical documentation and expanded empirical results beyond those presented in the main manuscript.
