INTRODUCTION

AI-Generated Comment on the Study



Understanding how people evacuate during natural disasters is essential for designing effective disaster response strategies. While conventional evacuation models typically assume that evacuees travel directly to the nearest shelter via the shortest route, real-world behavior is often much more complex.

This project investigates tsunami evacuation behavior during the 2024 Noto Peninsula Earthquake by analyzing anonymized smartphone-based human mobility data. The research combines behavioral trajectories with questionnaire surveys on risk perception and psychological characteristics, together with GIS analyses of hazard exposure, elevation, and shelter accessibility. By integrating these complementary data sources, the project seeks to explain why people choose particular evacuation routes and destinations rather than simply describing where they moved.

The findings contribute to the development of realistic evacuation behavior models that better reflect actual human decision-making. Such models can support more accurate disaster simulations, improve evacuation planning and guidance, optimize shelter allocation, and ultimately enhance community resilience against future tsunami disasters.
