RCN: Planning for a Modeling Collaboratory for Subduction Zone Science

俯冲带是地球演化的基本表现。俯冲带也是火山、地震、滑坡和海啸等一连串自然灾害的所在地，这些灾害往往发生在人口密度高的地区。因此，对我们地球的任何动态理解都必须包括俯冲带动态的全面理论框架，这样一个框架应该有助于监测和基于物理的预测，以履行我们对社会的基本责任。最近的几项社区工作侧重于俯冲带科学，包括该地质背景下的火山和巨型逆冲过程。该研究协调网络（RCN）将为科学家的合作和互动提供一个机制，以组织建模工作，了解俯冲带。特别是，该RCN将有助于确定知识差距，并有助于评估科学界所需的工具和战略，以利用来自国际俯冲带观测站的丰富数据集，并创建新一代多物理场和多尺度模型。该区域网络将加强国际合作，包括来自智利、哥斯达黎加、德国、希腊、印度尼西亚、意大利、日本、墨西哥、瑞士和英国的研究人员。RCN将有助于培训多样化的劳动力，外联工作将向广大公众宣传俯冲带科学的相关性。RCN将吸引不同的研究人员社区，包括早期职业研究人员和代表性不足的群体。这是一个研究协调网络，专注于俯冲带科学的建模合作实验室，并探索开发与巨型逆冲断层和弧火山系统相关的短期至长期变形的物理模型。对板块边界内地震周期和火山的物理理解仍然不完整，尽管数值模型已经有了巨大的改进。这意味着需要以更好的方式整合更多的观测、实验室数据和对潜在物理过程的更好理解，以探索影响构造和灾害时间演变的俯冲系统不同部分之间的相互作用。科学界准备统一现有的数据收集工作，设计新的观测和基础设施举措，并利用新的综合方法利用各种国际努力。该区域网络有几个目标：1）帮助识别知识差距; 2）开发多尺度、多物理场建模框架; 3）为综合模型开发和验证提供途径; 4）提供工具，将地质、岩石力学、地球物理和大地测量数据转换为可有效融入模型并用于模型验证的格式。这一努力将有助于开发和加强各种模型，从概念到数字模拟器，目的是研究俯冲带巨型逆冲断层的周期和相关的构造过程，包括岩浆迁移和火山爆发。这项工作将通过一系列的研讨会和社区互动来取得进展，以确保俯冲科学所涉及的研究人员和科学领域的广泛代表性。该奖项反映了NSF的法定使命，并被认为值得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来支持。

Subduction zones are fundamental expressions of the evolution of our planet. Subduction zones also host cascading natural hazards, from volcanoes, to earthquakes, to landslides and tsunamis, often in regions with high population density. Any dynamic understanding of our planet therefore has to include a comprehensive theoretical framework for subduction zone dynamics, and such a framework should have utility for monitoring and for physics-based forecasting to meet our fundamental responsibility to society. Several recent community efforts have focused on subduction zone science, including volcanic and megathrust processes within that geologic setting. This Research Coordination Network (RCN) will provide a mechanism for collaboration and interaction of scientists to organize modeling efforts to understand subduction zones. In particular, this RCN will serve to identify knowledge gaps and serve to evaluate the tools and strategies needed by the scientific community to leverage the rich data sets from international subduction zone observatories and tp create a new generation of multiphysics and multiscale models. This RCN will strengthen international collaboration, including researchers from Chile, Costa Rica, Germany, Greece, Indonesia, Italy, Japan, Mexico, Switzerland, and the United Kingdom. The RCN will contribute to the training of a diverse workforce, and outreach efforts will publicize the relevance of subduction zone science to the larger public. The RCN will engage a diverse community of researchers, including early career researchers and those from under-represented groups.This is a Research Coordination Network focuses on a modeling collaboratory for subduction zone science and explores developing physical models for short- to long-term deformation associated with megathrust and arc volcano systems. Physical understanding of earthquake cycles and volcanoes within a plate boundary remains incomplete, even though numerical models have seen tremendous improvements. This implies that more observations,laboratory data and better understanding of the underlying physical processes need to be integrated in better ways to explore interactions between different parts of the subduction system that affect the temporal evolution of tectonics and hazards. The scientific community is poised to unify existing data collection efforts, design new observational and infrastructural initiatives, and harness diverse international efforts with new integrative approaches. This RCN has several goals: 1) helping to identify knowledge gaps; 2) developing multiscale, multiphysics modeling frameworks; 3)providing a pathway for integrative model development and validation; and, 4) providing tools for transforming geological, rock mechanics, geophysical and geodetic data into formats that can be effectively assimilated into models and used for model validation. This effort would facilitate the development and enhancement of models, ranging from conceptual to numerical simulators, aimed at subduction zone megathrust cycles and associated tectonic processes including magma transport and volcanic eruptions. The work will progress through a series of workshops and community interactions to ensure a broad representation of the researchers and scientific fields involved in subduction science.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.
