Household Risk Perceptions and Hazard Adjustments to Earthquakes in Oklahoma

这项研究以俄克拉荷马州的地震为重点，提高了我们对人们对技术危害（即由技术引发的自然灾害）的风险认知的理解。地震在俄克拉荷马州是一个相对较新的现象，自2008年以来变得越来越普遍。当地居民缺乏应对这类危险的经验，不知道在地震发生时如何保护自己或财产。这一科研贡献支持了NSF促进科学进步和提高国家福利的使命。在这种情况下，好处将是为应急管理人员提供信息，以便制定帮助居民适应地震的计划和活动，同时考虑到与不同人口群体相关的特殊需求。该项目支持教育，并通过旨在招募和留住研究中代表性不足的学生的外展活动促进多样性。该项目考察了对灾害风险的基本理解，这些风险模糊了自然和技术之间的界限。它为应急管理人员提供了关键信息，他们可以利用这些信息鼓励当地家庭采取危险调整措施。它以现有的危险调整理论和最近的一项试点研究为基础，以解决五个研究目标：1)了解俄克拉何马州人对地震、风险感知和不同地震危险区调整水平的看法，2)调查不同人口群体家庭地震危险调整水平的差异，3)了解家庭对地震触发因素的看法（内生与外生），4)发现研究人员可以提高邮件调查回应率的方法，5)发展一种更好地描述家庭如何适应灾害的理论。通过了解家庭对地震灾害风险、起源和影响的认识，以及他们对应对这些威胁的能力和责任的理解，该项目为这些事件的技术评估提供了重要补充。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This research improves our understanding of the risk perceptions that people have regarding techna hazards (i.e., a natural disaster triggered by technology) with a focus on earthquakes in Oklahoma. Earthquakes are a relatively new phenomenon in Oklahoma, and have become increasingly common since 2008. Residents lack experience dealing with this type of hazard and do not know how to protect themselves or their property in the event of an earthquake. This scientific research contribution thus supports NSF's mission to promote the progress of science and to advance our national welfare. In this case, the benefits will be information for emergency managers to develop plans and campaigns to help residents adjust to earthquakes , taking into account the special needs associated with different demographic groups. The project supports education and promotes diversity through outreach activities aimed at recruiting and retaining under-represented students in research.This project examines the fundamental understanding of risk in relation to disasters that blur the line between natural and technological. It provides emergency managers with key information they can use to encourage local households to adopt hazard adjustment measures. It builds upon existing hazard adjustment theories and a recent pilot study to address five research objectives: 1) to understand Oklahomans' view of earthquakes, risk perceptions, and levels of adjustment in different earthquake risk zones, 2) to investigate differences in household earthquake hazard adjustment levels across different demographic groups, 3) to understand household views of earthquake triggers (endogenous vs. exogenous), 4) to discover ways researchers can increase their mail survey response rate, and 5) to develop a theory that better describes how households adjust to hazards. By capturing household perceptions of earthquake hazard risks, origins, and implications, along with their understanding of their ability and responsibility to address these threats, this project provides a critical complement to technical assessments of these events.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
