RAPID: Trajectories of Social Vulnerability among Houston Area Households: A Pre- and Post-event Study of Hurricane Harvey

飓风哈维于2017年8月25日袭击了德克萨斯州休斯顿大都市区，造成了前所未有的破坏。截至2017年9月4日，估计有超过156，000所房屋被毁，至少60人死亡。初步的损失估计表明，影响可能远远超过1000亿美元，使哈维成为美国历史上损失最大的灾难。该项目研究了影响飓风哈维引起的洪水经验，影响和休斯顿地区家庭的短期恢复的潜在因素。该项目利用了在飓风哈维之前从休斯顿地区家庭的代表性样本中收集的关于其对飓风和洪水的脆弱性的基线数据，并涉及从这些家庭快速收集哈维后的调查数据。通过澄清事前因素如何塑造家庭的经验，影响，并在哈维飓风期间和紧随其后的短期恢复，该项目提供了新的见解社区脆弱性与复原力的决定因素。正如“哈维”飓风期间所表明的那样，人们的决策在社区建成环境遭受极端事件时的脆弱性方面发挥着关键作用。通过收集和审查来自同一住户样本的活动前后调查数据，这个研究项目推进了我们对潜在的社会脆弱性在社区恢复力和恢复中的作用的认识，本项目的研究目标是收集飓风哈维后休斯顿的数据，以进一步了解洪水中社会脆弱性的表现经验、影响和短期恢复。该项目利用2012年从休斯顿地区随机选择的600户家庭收集的调查数据，并重新调查他们在飓风哈维引发的洪水中的经历、影响和短期恢复情况（2017年10月）。根据更新的联系信息，该项目将收集飓风哈维发生时仍居住在休斯顿地区的家庭的第二波调查数据。根据这项调查数据，将使用多变量统计模型，使用2012年和2017年调查中的解释变量，预测研究家庭的洪水经历、影响和短期恢复情况。

Hurricane Harvey hit the Houston, Texas, metropolitan area on 25 August, 2017 and caused unprecedented damage. As of 4 September, 2017, estimates indicate that over 156,000 homes were destroyed and at least 60 people died. Preliminary loss estimates suggest that impacts could well exceed $100 billion, making Harvey the costliest disaster in U.S. history. This project examines underlying factors influencing Hurricane Harvey-induced flood experiences, impacts, and short-term recovery across Houston area households. The project leverages baseline data collected before Hurricane Harvey from a representative sample of Houston area households regarding their vulnerability to hurricanes and flooding, and involves the rapid collection of post-Harvey survey data from those same households. By clarifying how pre-event factors shape households' experiences, impacts, and short-term recovery during and immediately following Hurricane Harvey, the project provides new insights into determinants of community vulnerability versus resilience. As was demonstrated during Hurricane Harvey, people's decision making plays a critical role in the vulnerability of a communities' built environment when subjected to extreme events. Through the collection and examination of a pre- and post-event survey data from the same sample of households, this research project advances our knowledge of the role of underlying social vulnerability in community resilience and recovery during and immediately following large-scale disasters.The research objective of this project is to collect data in Houston following Hurricane Harvey to further our understanding of how social vulnerability manifests in flood experiences, impacts, and short-term recovery. The project leverages survey data collected from 600 randomly selected Houston area households in 2012, and involves re-surveying them regarding their Hurricane Harvey-induced flood experiences, impacts, and short-term recovery (in October 2017). Based on updated contact information, the project will collect a second wave of survey data from households still residing in the Houston area at the time of Hurricane Harvey. With this survey data, multivariate statistical models will be used to predict flood experiences, impacts, and short-term recovery across study households using explanatory variables derived from the 2012 and 2017 surveys.
