这项研究计划试图描述卡斯卡迪亚北部俯冲带和弧前的地质灾害特征。新一波的星载和机载传感器正在改变我们绘制与地震断层相关的地表形变和地形的能力，使我们能够评估未来俯冲事件的破裂程度，并识别浅层上板块断层。该项目的动机是最近全球大型逆冲事件(例如2011年日本东北地震和海啸)和复杂上板块破裂(例如2016年新西兰凯库拉地震)的激增，这些事件正在迅速推翻先前关于俯冲带行为的共识。

This research program seeks to characterize geohazards across the northern Cascadia subduction zone and fore-arc. A new wave of spaceborne and airborne sensors are transforming our ability to map surface deformation and topography associated with earthquake faulting, enabling the rupture extents of future subduction events to be assessed and shallow, upper plate faulting to be identified. The project is motivated by a recent global surge in megathrust events (e.g. the 2011 Tohoku, Japan, earthquake and tsunami) and complex upper plate ruptures (e.g. the 2016 Kaikoura, NZ, earthquake) which are rapidly overturning previous consensus on subduction zone behaviour.
