NNA Research: Collaborative Research: Arctic, Climate, and Earthquakes (ACE): Seismic Resilience and Adaptation of Arctic Infrastructure and Social Systems amid Changing Climate

导航新北极（NNA）是美国国家科学基金会的十大构想之一。NNA项目解决快速变化的北极地区的融合科学挑战。这项北极研究需要为国家、更大地区和全球的经济、安全和复原力提供信息。NNA支持从地方到国际规模的新研究伙伴关系，使下一代北极研究人员多样化，加强正式和非正式教育的努力，并在适当情况下整合知识的共同生产。该奖项通过解决以下NNA重点领域的社会系统、自然环境和建筑环境之间的相互作用，实现了这一目标：北极居民、教育和弹性基础设施。阿拉斯加州和北极的许多其他地区都是地震活跃的地区，每年都会经历数千次不同震级的地震。考虑到北极地区对地震的脆弱性以及加速的环境和社会变化，在自然环境、建筑环境和社会系统的背景下评估该地区基础设施对地震事件的恢复能力，并了解这些变化如何相互作用和影响该地区对地震的准备和响应是至关重要的。该NNA合作研究项目的总体目标是：1)通过地震监测/建模、社区参与和对自然环境、建筑环境和社会系统相关组成部分之间相互作用的有针对性的调查，提高对北极变化对该地区未来地震准备和响应的影响的基本认识；2)通过向北极社区提供必要的培训和工具来管理未来与地震有关的灾害，包括规划、准备、减灾和恢复，增强北极社区的地震恢复能力。项目研究和教育活动将包括有针对性的研究、研讨会和劳动力发展，包括培训和指导新罕布什尔大学的三名研究生、佐治亚大学的一名研究生和一名本科生、宾夕法尼亚州立大学的一名研究生、阿拉斯加费尔班克斯大学的一名研究生和弗吉尼亚大学的一名研究生。这个NNA合作研究项目建立在一个规划拨款和一个研讨会的结果之上，该研讨会有大量的社区投入，确定了六个主要的社区关注和高优先级的研究课题，涉及新北极面临的地震挑战和该地区的准备和恢复能力，以管理未来与地震有关的灾害。为了应对这些挑战，NNA合作研究项目的首席研究员（pi）建议围绕四个战略支柱和目标开展一项融合研究和教育计划。研究的具体目标包括：1)通过对阿拉斯加关键基础设施系统的监测，结合离心机物理建模，模拟和评估永久冻土融化对土壤和建筑/基础设施基础的影响，评估北极地面气候驱动变化下的基础设施地震响应；2)通过调查、访谈，共同开发当地社区公平的地震恢复能力；3)通过系统动力学建模进行地震弹性建模和评估，审查地震设计/规划策略，以及社区和州一级的气候适应规划，以及4)通过ACE青年训练营，土著青年STEM研究经验和北极地震弹性和适应国际研讨会进行外展和教育。该项目的成功完成具有潜在的变革性影响，通过播种和催化研究，可以在社区参与和土著知识的指导下，在基础科学和工程方面取得突破，解决新北极面临的地震挑战，提高该地区对未来地震相关灾害的准备和响应。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。

Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. This Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region, and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems, natural environment, and built environment in the following NNA focus areas: Arctic Residents, Education, and Resilient Infrastructure.The state of Alaska and many other areas of the Arctic are seismically active, experiencing thousands of earthquakes with different magnitudes every year. Given the vulnerability of the Artic to earthquakes and the accelerating environmental and social changes, it is critical to evaluate the resiliency of the region’s infrastructure to seismic events in the context of the natural environment, built environment, and social systems and understand how these changes interact and impact the region’s preparedness and response to earthquakes. The overarching goals of this NNA Collaborative Research project are to: 1) Improve the fundamental understanding of the impact of Arctic changes on the region’s preparedness and response to future earthquakes through seismic monitoring/modeling, community engagement, and targeted investigations of the interactions between the relevant components of the natural environment, built environment, and social systems; and 2) Enhance the seismic resilience of Arctic communities by providing them with the necessary training and tools to manage future earthquake-related disasters including planning, preparedness, mitigation, and recovery. The project research and education activities will include targeted research studies, workshops, and workforce development including the training and mentoring of three graduate students at the University of New Hampshire, one graduate student and an undergraduate student at the University of Georgia, one graduate student at Pennsylvania State University, one graduate student at the University of Alaska Fairbanks, and one graduate student at the University of Virginia.This NNA Collaborative Research project builds upon the results of a planning grant and a workshop with significant community input that identified six major community concerns and high priority research topics regarding the seismic challenges facing the new Arctic and the region’s preparedness and resilience to manage future earthquake-related disasters. To address these challenges, the Principal Investigators (PIs) of this NNA Collaborative Research project propose to carry out a convergent research and education program structured around four strategic pillars and objectives. The specific objectives of the research include 1) Infrastructure seismic response assessment under climate-driven changes of the Arctic ground through the monitoring of key infrastructure systems in Alaska in combination with centrifuge physical modeling to simulate and evaluate the impact of permafrost thawing on soils and building/infrastructure foundations, 2) Co-development of equitable seismic resilience capacities for local communities through surveys, interviews, and participatory mapping workshops, 3) Seismic resilience modeling and assessment through systems dynamics modeling, review of seismic design/planning strategies, and climate adaptation planning at community and state levels, and 4) Outreach and education through ACE youth training camps, STEM research experience for Indigenous youth, and an international workshop on Arctic seismic resilience and adaptation. The successful completion of this project has the potential for transformative impact by seeding and catalyzing research that could lead to breakthroughs in fundamental science and engineering, informed by community participation and Indigenous knowledge, to address seismic challenges facing the new Arctic and improve the region’s preparedness and response to future earthquake-related disasters.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.
