RCN: Planning for a Modeling Collaboratory for Subduction Zone Science

俯冲带是地球演化的基本表现形式。俯冲带还孕育着层叠的自然灾害，从火山到地震，再到山体滑坡和海啸，往往发生在人口密度高的地区。因此，对地球的任何动态理解都必须包括俯冲带动力学的全面理论框架，这种框架应该对监测和基于物理的预测有用，以履行我们对社会的基本责任。最近社区的几项努力侧重于俯冲带科学，包括在该地质背景下的火山和巨型逆冲过程。这个研究协调网络(RCN)将为科学家之间的合作和互动提供一种机制，以组织建模工作以了解俯冲带。特别是，这一区域资源中心将有助于确定知识差距，并评价科学界利用国际俯冲区观测站的丰富数据集和建立新一代多物理和多尺度模型所需的工具和战略。该RCN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。区域协调中心将帮助培训一支多样化的劳动力队伍，外联工作将向广大公众宣传俯冲带科学的相关性。RCN将吸收不同的研究人员，包括早期职业研究人员和来自代表性不足群体的研究人员。这是一个研究协调网络，侧重于俯冲带科学的建模合作，并探索开发与巨型逆冲和弧形火山系统相关的短期和长期变形的物理模型。对板块边界内的地震周期和火山的物理理解仍然不完整，尽管数值模型已经看到了巨大的改进。这意味着更多的观测、实验室数据和对潜在物理过程的更好理解需要以更好的方式结合起来，以探索俯冲系统不同部分之间的相互作用，这些相互作用影响着构造和灾害的时间演化。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倡议，并利用新的综合方法利用不同的国际努力。RCN有几个目标：1)帮助确定知识差距；2)开发多尺度、多物理模型框架；3)提供综合模型开发和验证的途径；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地同化为模型并用于模型验证的格式。这项工作将有助于开发和加强各种模型，从概念模拟器到数值模拟器，目的是研究俯冲带大型逆冲旋回和相关的构造过程，包括岩浆运移和火山喷发。这项工作将通过一系列研讨会和社区互动进行，以确保参与俯冲科学的研究人员和科学领域的广泛代表性。这一奖项反映了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。

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.
