Relationship between displacement distance and duration after disasters. (a) The longer the evacuation distance, the longer the average evacuation duration. (b) Probability densities of maximum distance from home on a usual day (grey) and at various timings after the disaster day (brown: day of occurrence, red: 10 days after, orange: one month after) are all long-tailed. The long-tailed distribution of evacuation distances and the relationship between displacement distance and duration were common across disasters. The majority of people evacuating short distances (thus short duration) and a small fraction of the people evacuating extremely long distances (thus long duration) explains why similar negative exponential functions were observed after the disasters.
