Landslides are a common hazard in mountainous terrain worldwide, and they occur throughout all US states and territories. In the US alone, annual landslide-related losses have been estimated to be more than $2B with the loss of 25 to 50 lives. Worldwide landslides claimed more than 18,000 lives between 1998 and 2017. This Track I proposal will use Puerto Rico as a living laboratory to study landslides, related ground failure hazards, and their community impact. This proposal will develop a primary hub for a national center proposal in Track 2 as a collaboration between the Georgia Institute of Technology (GT), the University of Puerto Rico at Mayagüez (UPRM), and the University of Colorado Boulder (CUB). This primary hub will serve as a model for integrating research aims with community engagement, student education, and workforce development. Goals include the inclusion of historically underrepresented groups in cutting-edge scientific research, communicating landslide science to communities vulnerable to mass wasting, and preparing a new generation of subject matter experts and leaders. A “Landslide Ready” program for emergency managers and community leaders will underpin efforts to communicate landslide preparedness and hazard response best practices in a meaningful way.The Puerto Rico hub, and ultimately a Collaborative Center for Landslides and Ground Failure Geohazards, will focus research on the fundamental causes and triggering mechanisms of landslides as well as developing an understanding of hazards cascading from ground failure. The hub will provide a platform for fieldwork and modeling tools tailored specifically for landslide science. Scientific questions to be addressed by the national center include: Can we predict landslide triggering in complicated terrain? What are the interactions between rainfall, topography, and vegetation and landslide risk? Do landslides promote the release or capture of carbon? Can we forecast the post-event riverine flux of coarse sediment and its impacts on future flood hazards? Track I science objectives include developing the cyber-infrastructure for integrating data and models and formulating a landslide geohazard forecasting system for Puerto Rico.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.

山体滑坡是世界各地山区常见的危险，美国所有州和地区都会发生山体滑坡。仅在美国，每年与山体滑坡有关的损失估计就超过20亿美元，造成25到50人死亡。1998年至2017年，全球山体滑坡夺走了1.8万多人的生命。这项第一轨道计划将把波多黎各作为一个活的实验室，研究山体滑坡、相关的地面崩塌危害及其对社区的影响。该提案将为第二轨道上的国家中心提案建立一个主要中心，作为佐治亚理工学院(GT)、波多黎各大学马亚格斯分校(UPRM)和科罗拉多博尔德大学(CUB)之间的合作。这一主要枢纽将成为将研究目标与社区参与、学生教育和劳动力发展相结合的典范。目标包括将历史上代表性不足的群体纳入尖端科学研究，向易受大规模浪费影响的社区传播滑坡科学，以及培养新一代主题专家和领导人。为应急管理人员和社区领导人制定的“山体滑坡准备”计划将有助于以有意义的方式交流山体滑坡准备和灾害应对的最佳实践。波多黎各中心，最终是一个山体滑坡和地面崩塌地质灾害合作中心，将重点研究山体滑坡的根本原因和触发机制，以及对地面崩塌引发的级联灾害的理解。该中心将为现场工作和专门为滑坡科学量身定做的建模工具提供平台。国家中心要解决的科学问题包括：我们能否预测在复杂地形下引发山体滑坡的可能性？降雨、地形和植被与滑坡风险之间的相互作用是什么？山体滑坡是否促进了碳的释放或捕获？我们能预测灾后粗泥沙的河流流量及其对未来洪水灾害的影响吗？Track I的科学目标包括开发整合数据和模型的网络基础设施，以及为波多黎各制定滑坡地质灾害预报系统。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
