Paleo-seismic Record of the Northern End of the Cascadia Subduction Zone

加拿大西海岸地震危险模型中最大的不确定性是大型逆冲地震和相关海啸的频率和规模，这些地震和海啸有可能影响数百万加拿大人。这次研究巡航将提高我们对未知地震历史的认识，即卡斯卡迪亚俯冲带北部的“古地震历史”，这是过去地质时期发生的大地震和海啸的原因。不列颠哥伦比亚省沿岸的海洋沉积物的活塞岩心和冰冻岩心将从海底升起并进行分析，以准确识别和确定“震积岩”的年代，震积岩是受地震干扰的海底沉积物。2011年，在加拿大创新基金会和BC省的资助下，研究团队获得了最新的最先进的海洋沉积物岩心分析设备，称为多传感器岩心记录仪（MSCL），这是用于海洋沉积学研究的分析设备的国际标准。该设备提高了我们从海洋沉积物岩心中识别不列颠哥伦比亚省沿岸“震积岩”的能力。

The greatest uncertainties in the Earthquake Hazard Model for Canada's west coast are the frequency and size of megathrust earthquakes and associated tsunamis which have the potential to affect millions of Canadians. This research cruise will advance our knowledge of the unknown earthquake history, known as the "paleo-seismic history", of the northern part of the Cascadia subduction zone which is responsible for giant earthquakes and tsunamis which occurred in the geologic past. Piston cores and freeze cores of marine sediments all along the BC coast will be raised from the seafloor and analyzed to accurately identify and date "seismites" which are ocean floor sediments which have been disturbed by earthquakes. In 2011, with funding from the Canada Foundation for Innovation and the Province of BC, the research team acquired new state of the art marine sediment core analytical equipment called a Multi-Sensor Core Logger (MSCL), which is the international standard of analytical equipment used for marine sedimentology research. This equipment enhances our capability to identify "seismites" along the BC coast from marine sediment cores.
