Randomized trial quantifies tsunami evacuation potential in Panggarangan, highlighting socio-spatial complexities.

This study aims to assess tsunami evacuation potential by considering hazard timing, spatial constraints, and community behavior.
Analyzed tsunami arrival times and inundation from BMKG megathrust scenarios.
Utilized high-resolution topographic data and GIS for evacuation trajectory estimations.
Conducted ethnographic observations from 2022 to 2025 to integrate social dimensions.
Estimated evacuation times diminished due to compressed arrival windows of 12-15 minutes and topographic friction.
Behavioral latency factors like social confirmation reduced evacuation feasibility significantly.
Integrating socio-spatial factors provided a more nuanced understanding of tsunami risk assessment.

Jumantini et al. (2026) studied this question.
