The project aims to understand the multiscale dynamics of interacting faults on a global scale using novel computer simulations with unprecedented spatial and temporal resolution. The focus of the research is to investigate the two-way coupling that exists between cycles of great earthquakes on plate boundaries, the global stress field, deformation within the crust, and changes to the Earth's dynamic topography. This is an important, foundational question in the emerging field of decadal scale global geodynamics. The tools are intended to improve reference models used to study sea-level changes in response to global ice loss. They support better climate models and improved forward planning tools for at-risk coastal communities.

该项目旨在利用前所未有的空间和时间分辨率的新型计算机模拟，了解全球范围内相互作用断层的多尺度动力学。研究的重点是探讨板块边界大地震周期、全球应力场、地壳形变和地球动力地形变化之间存在的双向耦合。这是年代际尺度全球地球动力学新兴领域中的一个重要的基础性问题。这些工具旨在改进用于研究海平面变化以响应全球冰损失的参考模型。它们为面临风险的沿海社区提供了更好的气候模型和改进的前瞻性规划工具。
