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.

该研究计划旨在描述整个北方卡斯卡迪亚俯冲带和前弧的地质灾害。一波新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变形和地形的能力，使未来俯冲事件的破裂程度能够得到评估，并确定浅层，上板块断层。该项目的动机是最近全球大规模逆冲事件激增（例如2011年日本东北部地震和海啸）和复杂的上板块破裂（例如2016年新西兰凯库拉地震），这些事件正在迅速推翻以前对俯冲带行为的共识。
