Hurricane Fiona severely impacted Southwestern Puerto Rico, provoking landslides, unleashing flooding across the Island, and obliterating the power grid. Such impacts are quite unusual for a Category 1 hurricane, raising concerns about disaster-preparedness of the US Territory that faces a multilayered socioeconomic crisis rooted in long-standing policy, migration, and poor budget practices. While it is well-known that disasters and subsequent recovery efforts exacerbate the socioeconomic disparities among marginalized groups, there is a lack of understanding of how these groups are being impacted by the cascading critical infrastructure (CI) failures and delays in the restoration process. While the role of CI interdependencies has gained importance for analyzing cascading failures, their linkage to restoration activities after a hurricane and the compounding effect on community recovery have not yet been extensively studied or systematically documented. This Grant for Rapid Response Research (RAPID) award supports the collection of time-sensitive data to study the impacts of cascading hurricane-induced failures of electric and transportation networks on socially vulnerable Puerto Rican communities and to understand the relationships between CI restoration activities and faster community recovery. The research findings will fill an important data gap for the development of community-based multi-infrastructure optimal recovery and reconstruction strategies.This research will quantify the impacts of cascading failures of power grid and transportation systems on socially vulnerable communities and capture the dynamic relationships of CI restoration interdependencies with the community recovery process. In addition to data collected from publicly available sources, the research team will conduct interviews and focused-group surveys of the emergency managers and infrastructure operators to understand the multidimensional impacts on the hardest-hit Puerto Rican communities and investigate how the restoration decisions are associated with the challenges and resource constraints. The team will also conduct a focused-group survey of the households from communities of high social vulnerability to document their actual and perceived harms owing to hurricane-induced infrastructure failure and the delayed community recovery. This project will generate valuable information to better inform decision-makers to anticipate future disruptions in CI systems and plan for efficient and equitable restoration strategies.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.

飓风菲奥娜严重影响了波多黎各西南部，引发山体滑坡，整个岛屿引发洪水，并摧毁了电网。这样的影响对于1级飓风来说是相当不寻常的，这引起了人们对美国领土的防灾准备的担忧，美国领土面临着植根于长期政策、移民和糟糕预算实践的多层次社会经济危机。众所周知，灾难和随后的恢复工作加剧了边缘群体之间的社会经济差距，但人们对这些群体如何受到级联关键基础设施（CI）故障和恢复过程中的延迟的影响缺乏了解。虽然CI相互依赖的作用在分析级联故障方面变得越来越重要，但它们与飓风后恢复活动的联系以及对社区恢复的复合效应尚未得到广泛研究或系统记录。这项快速反应研究拨款（Rapid）支持收集对时间敏感的数据，以研究飓风引发的电力和交通网络连锁故障对波多黎各社会脆弱社区的影响，并了解CI恢复活动与更快的社区恢复之间的关系。研究结果将为制定基于社区的多基础设施最优恢复重建策略填补重要的数据空白。本研究将量化电网和交通系统级联故障对社会脆弱社区的影响，并捕捉CI恢复相互依赖与社区恢复过程的动态关系。除了从公开来源收集的数据外，研究小组还将对应急管理人员和基础设施运营商进行访谈和重点小组调查，以了解对受灾最严重的波多黎各社区的多方面影响，并调查恢复决策如何与挑战和资源限制相关联。该小组还将对来自社会高度脆弱社区的家庭进行重点小组调查，以记录他们因飓风导致的基础设施故障和社区恢复延迟而遭受的实际和感知伤害。该项目将产生有价值的信息，更好地为决策者提供信息，以预测CI系统未来的中断，并制定有效和公平的恢复策略。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。
