The Principal Investigators will install instrumentation to observe strain build-up and fluid behavior near the up-dip end of the Cascadia Subduction Zone. The project will establish a borehole geodetic observatory offshore of Vancouver adjacent to an existing CORK observatory, which will be enhanced with tiltmeters and temperature-monitoring instrumentation. Real-time data will be streamed onshore and made available to the community via the NEPTUNE Canada system. Long-term data analysis goals include capturing and characterizing slow-slip events and/or major earthquakes. The project will enhance scientific infrastructure and produce widely accessible data that will advance understanding of earthquake and tsunami hazards. A graduate student at RSMAS will be supported and at WHOI students and/or post-doctoral researchers will be involved in the cruise and data analysis.

主要调查人员将安装仪器，以观察卡斯卡迪亚俯冲带上倾端附近的应变积累和流体行为。 该项目将在温哥华近海建立一个钻孔大地测量观测站，毗邻现有的CORK观测站，将用倾斜仪和温度监测仪器加强观测站。实时数据将通过加拿大NEPTUNE系统向岸上传输并提供给社区。长期数据分析目标包括捕获和表征慢滑事件和/或大地震。该项目将加强科学基础设施，并提供可广泛获取的数据，以增进对地震和海啸危害的了解。RSMAS的一名研究生将得到支持，WHOI的学生和/或博士后研究人员将参与航行和数据分析。
