This study explores household-level evacuation decision-making in response to Hurricane Laura, in a context where hurricane risk reduction measures contradicted COVID-19 risk reduction measures. Data were collected using a mail-based survey approach from households along the coast of Texas and Louisiana to explore drivers of and barriers to evacuation, including COVID-19 measures such as negative affect, risk perceptions, protective actions, and exposure. Testing for direct and indirect effects among the drivers of and barriers to evacuation, we find that many of our COVID-19 measures did not have a direct effect on evacuation but did have indirect effects through other factors. We also found evidence of both direct and indirect relationships with regards to more conventional drivers of evacuation found in the literature. We close with a discussion of the limitations and implications of this study. 

While existing literature has explored how hazard experience, salience, and demographics characteristics shape threat appraisal and hazard adjustment intentions, this study expands on past studies by exploring how additional factors such as qualitative characteristics of the hazard, political ideology, and oil entanglements shape threat appraisals, coping appraisals, and adjustment intentions in response to a techna hazard. This study builds on protection motivation theory (PMT) to explore factors that shape Oklahomans’ intentions to adjust to induced seismicity using data collected from households (n=866) across 27 counties in Oklahoma that have experienced varying levels of seismic activity resulting from oil and gas exploration. Correlational analyses and structural equation modeling show that several variables not included in the original PMT, such as feelings of dread or negative emotions associated with earthquakes, are important predictors of intentions to adopt hazard adjustments. This study concludes with examining the effect of additional factors on adjustment intentions and risk perceptions that can help guide future earthquake risk management in identifying and taking appropriate actions that will stimulate precautionary behavior of private actors. 

Abstract Tornadoes are responsible for considerable property damage and loss of life across the state of Oklahoma. While several studies have explored drivers of tornado adjustment behaviors, their results are not consistent in terms of their significance and direction. To address this shortcoming in the literature, we surveyed households using a disproportionate stratified sampling procedure from counties in Oklahoma that frequently experience tornado threats to explore drivers of adjustments. We used Structural Equation Modeling (SEM) to explore relationships among variables highlighted in the Protection Motivation Theory (PMT) and related literature that affect adjustment intentions and risk perceptions. Overall, we found the factors highlighted in the PMT are effective at explaining households’ intentions of adopting adjustment behaviors associated with tornado hazards. Threat appraisals, however, were less important than coping appraisals in explaining tornado hazard adjustment intentions. In further analysis, we grouped adjustments as 1) basic (e.g., flashlight, food and water supply) and 2) complex (e.g., insurance, storm shelter), and found that while coping appraisals are significant drivers of both adjustment categories, the effect of threat appraisals is only significant for complex adjustment intentions. We also found that emotional responses to hazards are major drivers of threat appraisals, stronger than perceived knowledge and hazard salience. Moreover, we found that demographic characteristics affect both adjustment intentions and threat appraisals. The additions to the PMT and categorization of adjustment activities improve our understanding of the PMT in different contexts. Such insights provide scholars and emergency managers with strategies for risk communication efforts. 

This study investigates how different risk predictors influenced households’ evacuation decisions during a dual‐threat event (Hurricane Laura and COVID‐19 pandemic). The Protective Action Decision Model (PADM) literature indicates that perceived threat variables are the most influential variables that drive evacuation decisions. This study applies the PADM to investigate a dual‐threat disaster that has conflicting protective action recommendations. Given the novelty, scale, span, impact, and messaging around COVID‐19, it is crucial to see how hurricanes along the Gulf Coast—a hazard addressed seasonally by residents with mostly consistent protective action messaging—produce different reactions in residents in this pandemic context. Household survey data were collected during early 2021 using a disproportionate stratified sampling procedure to include households located in mandatory and voluntary evacuation areas across the coastal counties in Texas and parishes in Louisiana that were affected by Hurricane Laura. Structural equation modeling was used to identify the relationships between perceived threats and evacuation decisions. The findings suggest affective risk perceptions strongly affected cognitive risk perceptions (CRPs). Notably, hurricane and COVID‐19 CRPs are significant predictors of hurricane evacuation decisions in different ways. Hurricane CRPs encourage evacuation, but COVID‐19 CRPs hinder evacuation decisions.

 

Oklahoma is a multihazard environment where both natural (e.g., tornadoes) and technological hazards (e.g., induced seismicity) are significant, making Oklahoma a unique setting to better understand how to manage and prepare for multiple hazards. While studies have attempted to understand drivers of hazard adjustments, few have focused on the overall number of adjustments undertaken instead of individual adjustments or adjustments in a multihazard environment. To address these gaps, we employ a survey sample of 866 households in Oklahoma to understand households’ danger control responses (protective hazard adjustments) for tornado and earthquake risks in Oklahoma. We apply the extended parallel processing model (EPPM) to categorize respondents according to their relative level of perceived threat and efficacy of protective actions in predicting the number of hazard adjustments they intend to or have adopted in response to tornadoes and induced earthquakes. In line with the EPPM, we found that households have the highest number of danger control responses when their perceived threat and efficacy are both high. Counter to the EPPM literature, we found low threat coupled with high efficacy moved some individuals toward the adoption of danger control responses in response to both tornadoes and earthquakes. When households have high efficacy, threat appraisals matter in tornado danger control responses but not in earthquake danger control responses. This EPPM categorization opens new research approaches for studies of natural and technological hazards. This study also provides information for local officials and emergency managers making mitigation and preparedness investments and policies.

 

Abstract Scholars have produced several theories and models to explain why individuals adjust to hazards. While findings from these studies are informative, studies have not considered how threat and coping appraisals may have differential effects on varying types of hazard adjustments, or how these findings may generalize to vulnerable populations. This study expands on the Protection Motivation Theory to explore the factors that shape hazard adjustment intentions among college students, a population traditionally defined as vulnerable, in response to tornado risk. An online survey was administered to college students (n=377) at Oklahoma State University, situated in a region that experiences considerable tornado risk. While the correlations between threat appraisal and tornado hazard adjustment intentions are smaller than the correlations between coping appraisal and tornado hazard adjustment intentions, findings suggest that threat appraisals become more important for influencing college students’ adjustment intentions when adjustment activities are complex (e.g., tornado shelter, home insurance), rather than basic (e.g., flashlight, first aid kid). This suggests that while both threat appraisals and coping appraisals are important for complex hazard adjustment intentions, basic hazard adjustment intentions are almost exclusively determined by coping appraisals. These findings have several practical implications for emergency management and provide new avenues for future hazard adjustment studies. 

Purpose Home buyout programs are typically funded by the federal government and implemented by local agencies. How these agencies design and implement buyouts has considerable impacts on participating households and communities, making understanding the internal processes of implementing agencies a critical component of buyout research. This study addresses this issue by exploring the early design and implementation phases of a buyout program in Harris County, Texas, following Hurricane Harvey. Design/methodology/approach Data were collected via semi-structured interviews with buyout staff and government stakeholders. Data were analyzed in two phases using grounded theory methodology and holistic coding. Findings There was considerable tension regarding the role of buyouts in mitigation and recovery. Participants conceptualized buyouts as mitigation programs, but recognized that residents, in contrast, viewed buyouts as a tool for household recovery. Research limitations/implications This study adds to questions raised in the literature about the efficacy of buyouts and other relocation efforts implemented in response to disasters and global climate change. Future research should work to build systematic knowledge regarding design, implementation, and impacts of buyouts on affected households and communities. Practical implications Tension in the purpose of buyouts may be the cause of consistent shortcomings in buyout implementation including attrition, checkerboarding, and transfer of risk. Funding, timing, and the scale of buyouts do not align with household recovery needs and priorities, limiting the mitigation potential of buyouts. Originality/value This study identifies a fundamental tension in the purpose of buyout programs that has yet to be discussed in the literature. 

Home buyout programs are implemented in the aftermath of disasters, with the goal of moving households or entire communities out of areas that are at risk for a future hazard event. Buyout programs offer residents pre‐disaster market value for their homes to relocate away from a hazardous area, and land purchased through buyouts is required to be maintained as open space in perpetuity. Our understanding of how these programs impact affected households and communities, however, is limited. Using a mixed methods design, 36 residents of Oakwood Beach, NY, were asked to describe their experiences with a home buyout program that was implemented in their community after Hurricane Sandy in 2012. While survey results showed that residents were generally satisfied with the buyout, a different picture emerged when they were asked to qualitatively describe the process of being bought out. Their experiences centered around three themes: (i) lack of information and communication from buyout officials; (ii) challenges surrounding the process of sale; and (iii) the buyout as a foregone conclusion. In light of these findings, recommendations are made to inform future home buyout programs and relocation policies.
