Abstract This study sheds new light on how a hurricane affects spatial reactions and mobility across the US states based on Twitter data, whereas prior studies have only focused on the damaged region. First, this study finds that spatial reactions are differentiated by periods. For example, New York shows the second-highest reactions in the pre-hurricane weeks, North Carolina reveals the second-highest reactions in the hurricane weeks, and Texas exhibits the second-highest reactions in the post-hurricane weeks. This study also highlights that a hurricane plays a significant role in spatial displacements of the case study regions (Florida, North Carolina, and New York). To be specific, displacements in the hurricane weeks are 24 times higher than those in the pre-hurricane weeks. Lastly, this study finds that displacements within 5 km significantly increase, whereas those over 50 km significantly decrease in the hurricane weeks.

1 Introduction Natural disasters have exerted serious damages to human environments and property. For instance, according to the National Oceanic and Atmospheric Administration (NOAA), the USA has sustained natural disasters where the cumulative damage cost exceeded $1.75 trillion between 1980 and 2019 (NOAA 2020a). Among the natural disasters, hurricanes dominate the distribution of damage in the USA. Hurricanes have caused the most damage ($919.7 billion), the highest average even cost ($21.9 billion per event), and 55.1% of the total losses for natural disasters. The cumulative cost of Hurricane events in 2017 is $306.2 billion, breaking the previous cost record of $214.8 billion in 2005 (Climate.gov 2019). In this vein, it is an important issue how hurricanes play an important role in spatial reactions and mobility (this study defines spatial reactions as behaviors across regions and mobility as movements of people in response to natural disasters) (see, e.g., Qi 2014; Wang and Taylor 2014, 2016). However, to the best of my knowledge, there is no research * Seungil Yum [email protected] 1

exploring the effect of a hurricane on spatial reactions and mobility across the US states (see, e.g., Congleton 2006; Elsner and Jagger 2006; Pielke and Landsea 1998; Pielke et al. 2008). Prior studies have explored the effects of other natural disasters, such as droughts and floods, on spatial reactions or environments. For instance, Kim et al. (2019) show the relationship between droughts and public reactions across the US states by employing Google Trends data and principal component analysis between 2004 and 2017. Schlef et al. (2019) highlight that the association between large flood events and atmospheric circulation patterns across the USA based on self-organiz
