Human mobility is influenced by environmental change and natural disasters.Researchers have used trip distance distribution, radius of gyration ofmovements, and individuals' visited locations to understand and capture humanmobility patterns and trajectories. However, our knowledge of human movementsduring natural disasters is limited owing to both a lack of empirical data andthe low precision of available data. Here, we studied human mobility usinghigh-resolution movement data from individuals in New York City during and forseveral days after Hurricane Sandy in 2012. We found the human movementsfollowed truncated power-law distributions during and after Hurricane Sandy,although the {\beta} value was noticeably larger during the first 24 hoursafter the storm struck. Also, we examined two parameters: the center of massand the radius of gyration of each individual's movements. We found that theirvalues during perturbation states and steady states are highly correlated,suggesting human mobility data obtained in steady states can possibly predictthe perturbation state. Our results demonstrate that human movementtrajectories experienced significant perturbations during hurricanes, but alsoexhibited high resilience. We expect the study will stimulate future researchon the perturbation and inherent resilience of human mobility under theinfluence of natural disasters. For example, mobility patterns in coastal urbanareas could be examined as tropical cyclones approach, gain or dissipate instrength, and as the path of the storm changes. Understanding nuances of humanmobility under the influence of disasters will enable more effectiveevacuation, emergency response planning and development of strategies andpolicies to reduce fatality, injury, and economic loss.
