This proposal seeks limited funds to provide partial support for two to three graduate students at any given year over the next five years as part of my research program. The proposed research is designed to understand the works of subduction zones, for which the Cascadia subduction zone off Canada’s west coast is a near-home example. The students will study what enables megathrust faults to generate large earthquakes and what makes them creep in slow slip events, how stress is built up and relieved in earthquake cycles to affect the geology of the upper plate, whether and why seismic activities in areas very far apart are physically connected, and so forth. The proposed research addresses fundamental geodynamics, and it helps society to understand what causes seismic and tsunami hazards. Our main method is to use computer modelling to explain global multidisciplinary observations to reveal underlying physical principles. The students are directed to develop geodynamic concepts from large volumes of observations and basic principles, not merely from textbooks and conventional models.

作为我的研究计划的一部分，该提案寻求有限的资金在未来五年内的任何一年中为两到三名研究生提供部分支持。拟议的研究旨在了解俯冲区的作品，加拿大西海岸附近的卡斯卡迪亚俯冲带就是一个​​近乎家庭的例子。学生将研究使大型断层产生大地震的原因，以及使它们在慢速滑移事件中蔓延的原因，如何在地震周期中积累和救出压力，以影响上层板块的地质，无论区域中分开的地震活动以及为什么物理上的地震活动都与众不同。拟议的研究涉及基本的地球动力学，并帮助社会了解导致地震和海啸危害的原因。我们的主要方法是使用计算机建模来解释全球多学科观察，以揭示基本的物理原理。指示学生从大量的观察和基本原理中发展出地球动力学概念，而不仅仅是教科书和传统模型。
