Physics-based forecasts of seismic hazard from future earthquakes are important for developing plans for land use, building codes, transportation and communication infrastructure, power and water systems, and many other aspects that are integral to society. The Quakeworx framework is a new multi-disciplinary collaboration to enable a wide community of users to access state-of-the-art physics-based models of rupture forecasts, further improve existing tools, and validate model results. Quakeworx also helps advance the science of rupture forecasts, obtain new insights on earthquake physics, improve seismic hazard estimates, and create new opportunities for STEM education and engagement. Quakeworx enables rapid immersion of students, post-docs, and early career scientists with state-of-the-art simulation and analysis tools that aid in modernizing education and training in earthquake physics, computational modeling, software engineering, and related fields. The project contributes to the national interest by supporting a more resilient society with improved capabilities for forecasting earthquakes and assessing seismic hazard, which are foundational for mitigation of seismic risk, contributing to STEM workforce development, and facilitating translation of results to the society at large.A core element of Quakeworx is a new science gateway, which provides access to state-of-the-art methods that combine novel physics-based modeling frameworks with standardized pipelines for simulations, data-based assimilation to inform and validate models on-demand, and machine-learning pattern recognition on big datasets. The project enables simulations of coupled evolution of earthquakes and faults producing diverse outputs (seismicity, ground motion, fault network configuration, strain rates, topography), and facilitates the development, validation, application, and reproducibility of improved rupture forecasts for research and education. Quakeworx curates and seeds many leading tools and data products that leverage existing community data models describing fault and rock properties as simulation input. Additionally, the gateway enables the research and education community to contribute, curate and share tools for simulations, data analysis and visualization, data products and knowledge base. The project provides a foundation that eliminates barriers due to lack of expertise and lack of access to compute resources, and it delivers an innovative service-oriented and easy-to-use cyberinfrastructure to a large user community.This award by the NSF Office of Advanced Cyberinfrastructure is jointly supported by the Division of Research, Innovation, Synergies, and Education (RISE), the Division of Earth Sciences (EAR), and the Geophysics Program within the NSF Directorate for Geosciences.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.

基于物理的未来地震灾害预测对于制定土地使用、建筑法规、交通和通信基础设施、电力和供水系统以及社会不可或缺的许多其他方面的计划非常重要。Replaceworx框架是一个新的多学科合作，使广大用户能够访问最先进的基于物理的破裂预测模型，进一步改进现有工具，并验证模型结果。Escherkeworx还有助于推进破裂预测科学，获得地震物理学的新见解，改善地震危险估计，并为STEM教育和参与创造新的机会。Quakeworx使学生、博士后和早期职业科学家能够快速沉浸在最先进的模拟和分析工具中，这些工具有助于地震物理、计算建模、软件工程及相关领域的教育和培训现代化。该项目通过支持一个更具弹性的社会，提高预测地震和评估地震危险的能力，这是减轻地震风险的基础，有助于STEM劳动力的发展，并促进将结果转化为整个社会，从而为国家利益做出贡献。它提供了最先进的方法，这些方法将联合收割机新颖的基于物理的建模框架与模拟的标准化管道相结合，基于数据的同化以按需通知和验证模型，以及大数据集上的机器学习模式识别。该项目能够模拟地震和断层的耦合演化，产生不同的输出（地震活动性，地面运动，断层网络配置，应变率，地形），并促进改进破裂预测的开发，验证，应用和再现性，用于研究和教育。Sparkeworx策划和播种了许多领先的工具和数据产品，这些工具和产品利用现有的社区数据模型描述断层和岩石属性作为模拟输入。此外，该网关使研究和教育界能够贡献，策划和共享模拟，数据分析和可视化，数据产品和知识库的工具。该项目提供了一个基础，消除了由于缺乏专业知识和无法访问计算资源而造成的障碍，并为大型用户社区提供了一个创新的面向服务和易于使用的网络基础设施。NSF高级网络基础设施办公室的这一奖项由研究，创新，协同和教育部（RISE），地球科学部（ESTA），该奖项反映了NSF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。
