The present paper examines the role of several demographic indicators on stated hurricane evacuation thresholds, or the lowest category storm for which participants indicated they would evacuate, for mandatory and voluntary orders. Quantitative analyses reveal that race was significantly associated with a lower stated evacuation threshold in both the bivariate and multivariate models and that previous refusal to comply with evacuation orders was associated with higher stated evacuation thresholds. Qualitative analyses reveal two key findings: (1) wind is perceived as more dangerous than water (rain and storm surge) associated with hurricanes; (2) traffic concerns were the most frequently cited reason listed for possible refusal to comply with evacuation orders. Implications of the findings include the value of future evaluations of race and trust, storm characteristics and threat perception, and other practical considerations for improving evacuation compliance such as the amelioration of traffic concerns. Findings also lead to the discussion of the social complexities of race and hurricane vulnerability as a key finding. 相似文献

Abstract This paper examines the relationship between household evacuation decisions and official emergency management practices in light of recent increases in the availability and diversity of hurricane-related information. While we focus on Hurricane Floyd in South Carolina, we incorporate findings of our longitudinal research effort covering the last four years and six post-1995 hurricane threats to the state. While only 64% of residents in the mandatory evacuation zone complied with the Hurricane Floyd evacuation order, over 80% agreed that calling an evacuation was an appropriate precautionary response given the uncertainties of the storm. Longitudinal surveys indicate that Horry County residents have developed a fairly robust strategy in making evacuation decisions. This “hurricane savvy” population depends more heavily on individuals' assessments of risks than on official orders. Individual assessment practices differ from official orders in that greater weight is given to household circumstances and preferences, the diligent monitoring of a variety of information sources, and the incorporation of past experiences into the decision-making process. Surveys indicate differences between the general public and officials in terms of priorities and preferences about hurricane evacuations. The public demands more information about the hurricane threat. Officials place more emphasis on planning evacuation routes and public safety measures. 相似文献

Data obtained from 65 executives working for tourism firms in three sample communities permitted comparison with the public warning response literature regarding three topics: disaster evacuation planning, initial warning responses, and disaster evacuation behavior. Disaster evacuation planning was reported by nearly all of these business executives, although it was highly variable in content, completeness, and formality. Managerial responses to post-disaster warnings paralleled the type of complex social processes that have been documented within the public response literature, except that warning sources and confirmation behavior were significantly affected by contact with authorities. Five key areas of difference were discovered in disaster evacuation behavior pertaining to: influence of planning, firm versus family priorities, shelter selection, looting concerns, and media contacts. 相似文献

At least 225 people in the Fiji Islands died as a result of the 1931 hurricane and flood, representing the largest loss of life from a natural disaster in Fiji's recent history. This paper explores the causes of disaster and the potential for recurrence. The disaster occurred because a rare event surprised hundreds of people—especially recently settled Indian farmers—occupying highly exposed floodplains in north‐west Viti Levu island. The likelihood of a flood disaster of such proportions occurring today has been diminished by changed settlement patterns and building materials; however, a trend towards re‐occupancy of floodplains, sometimes in fragile dwellings, is exposing new generations to flood risks. The contribution of this paper to the global hazards literature is set out in three sections: the ethnicity, gender and age of flood fatalities; the naturalness of disasters; and the merit of choice and constraint as explanations for patterns of vulnerability. 相似文献

We analysed 2003 and 2004 Behavioral Risk Factor Surveillance System (BRFSS) data from New Orleans-Metairie-Kenner, LA to produce estimates of the number of community dwelling people aged 65 years or older with a disability and requiring special equipment.(4) Approximately, 47,840 (31.6 per cent) older adults with a disability and 24,938 (16.6 per cent) older adults requiring the use of special equipment were community dwelling and might require assistance to evacuate or a shelter that could accommodate special equipment. Older adults who need special equipment were likely to be female, unmarried and white, and to rate their health as fair or poor. Personnel who plan and prepare for evacuations and temporary shelter during disasters need baseline information on the number of older adults with a disability or who require special equipment. A surveillance system, such as the BRFSS, gathers information that planners can use to prepare for and to deliver services. 相似文献

Hurricane Iwa (23rd November 1982) produced Hawaii's costliest natural disaster and revealed serious flaws in the area's hurricane preparedness, response and mitigation programs. Twenty-eight months later, a follow-up study showed that impacted communities and facilities had been reconstructed with only selective and limited attention to mitigating future coastal storm hazards. Prospects for the reduction of hazard vulnerability on oceanic islands through post-disaster mitigation measures are assessed in the light of Hawaii's experience. 相似文献

Over the last few years, hurricane emergencies have been among the most pervasive major disruptions in the United States, particularly in the south‐east region of the country. A key aspect of managing hurricane disasters involves logistical planning to facilitate the distribution and transportation of relief goods to populations in need. This study shows how a variant of the capacitated warehouse location model can be used to manage the flow of goods shipments to people in need. In this application, the model is used with protocols set forth in Florida's Comprehensive Emergency Plan and tested in a smaller city in north Florida. Scenarios explore the effects of alternate goods distribution strategies on the provision of disaster relief. Results show that measures describing people's accessibility to relief goods are affected by the distribution infrastructure used to provide relief, as well as assumptions made regarding the population(s) assumed to be in need of aid. 相似文献

Effectively controlling the spread of contagious illnesses has become a critical focus of disaster planning. It is likely that quarantine will be a key part of the overall public health strategy utilised during a pandemic, an act of bioterrorism or other emergencies involving contagious agents. While the United States lacks recent experience of large-scale quarantines, it has considerable accumulated experience of large-scale evacuations. Risk perception, life circumstance, work-related issues, and the opinions of influential family, friends and credible public spokespersons all play a role in determining compliance with an evacuation order. Although the comparison is not reported elsewhere to our knowledge, this review of the principal factors affecting compliance with evacuations demonstrates many similarities with those likely to occur during a quarantine. Accurate identification and understanding of barriers to compliance allows for improved planning to protect the public more effectively. 相似文献

Recent experience of hurricanes, particularly in the southeast United States, has heightened awareness of the multifaceted nature of and the challenges to effective disaster relief planning. One key element of this planning is providing adequate shelter at secure locations for people who evacuate. Some of these individuals will have ‘special needs’, yet there is little research on the relationship with shelter space. This study designed a geographic information systems‐based network optimisation methodology for the siting of special needs hurricane relief shelters, with a focus on the transportation component. It sought to find new locations for shelters that maximise accessibility by vulnerable populations, given capacity constraints, concentrating on the ageing population. The framework was implemented in a medium‐sized metropolitan statistical area in the state of Florida where data suggest a possible deficit in special needs shelter space. The study analysed options for increasing special needs shelter capacity, while considering potential uncertainties in transportation network availability. 相似文献

A traditional view of decision‐making for evacuation planning is that, given an uncertain threat, there is a deterministic way of defining the best decision. In other words, there is a linear relation between threat, decision, and execution consequences. Alternatives and the impact of uncertainties are not taken into account. This study considers the ‘top strategic decision‐making’ for mass evacuation owing to flooding in the Netherlands. It reveals that the top strategic decision‐making process itself is probabilistic because of the decision‐makers involved and their crisis managers (as advisers). The paper concludes that deterministic planning is not sufficient, and it recommends probabilistic planning that considers uncertainties in the decision‐making process itself as well as other uncertainties, such as forecasts, citizens responses, and the capacity of infrastructure. This results in less optimistic, but more realistic, strategies and a need to pay attention to alternative strategies. 相似文献

Abstract Using interview data, we examine the effects of the heavily publicized delays in reentering the Florida Keys after Hurricane Georges on future evacuation intent. Of particular interest is the finding that the delays will have less influence on the future evacuation decisions of those who experienced them than on those who learned of them from secondary sources. Fear of return delays is only one factor in evacuation decision-making, albeit an understudied one. For this sample of evacuees, perceived risk is the most salient factor, and this risk assessment is not sufficiently diminished by the inconveniences, such as delays, associated with evacuation. For non-evacuees, however, the delay factor appeared to only increase their reluctance to evacuate the next time, despite their level of perceived risk. 相似文献

Official response to explosive volcano hazards usually involves evacuation of local inhabitants to safe shelters. Enforcement is often difficult and problems can be exacerbated when major eruptions do not ensue. Families are deprived of livelihoods and pressure to return to hazardous areas builds. Concomitantly, prevailing socio-economic and political conditions limit activities and can influence vulnerability. This paper addresses these issues, examining an ongoing volcano hazard (Tungurahua) in Ecuador where contextual realities significantly constrain responses. Fieldwork involved interviewing government officials, selecting focus groups and conducting surveys of evacuees in four locations: a temporary shelter, a permanent resettlement, with returnees and with a control group. Differences in perceptions of risk and health conditions, and in the potential for economic recovery were found among groups with different evacuation experiences. The long-term goal is to develop a model of community resilience in long-term stress environments. 相似文献

This paper examines how and if the post-disaster distribution of housing assistance in two cities of Bam, in Iran, and Bhuj, in India, fulfilled the broad aim of enabling the stricken population to achieve housing recovery. Drawing on interviews with stricken households and officials as well as document review, the paper provides an account of the housing assistance distribution policies in these cities as they were formed, evolved, interpreted, and implemented as well as the ways they were experienced by disaster-stricken people. The paper investigates who did not receive assistance, who did not recover (yet) despite receiving assistance, and – in contrast to these groups – who recovered/accumulated new assets during the recovery process. While in both cities public policies of assistance distribution expanded the capacity of the majority of the stricken people to recover, they failed to provide a timely and appropriate support for the recovery of lower income groups, tenants, and squatters, in line with their needs and priorities. 相似文献
