The northern Canadian Cordillera, encompassing Yukon and western Northwest Territories, is an ideal natural laboratory for research in observational seismology because of the rich diversity of tectonic structures and earthquake activity taking place in this part of the continent (~130 M>3 earthquakes per year). Unfortunately, current coverage of seismic instrumentation by the Canadian National Seismograph Network is vastly insufficient for the kind of transformative research in seismology that would be afforded by a denser network. This proposal thus seeks funding to support research activities related to the installation and maintenance of a regional network of 10 state-of-the-art broadband seismograph stations in the Yukon and Northwest Territories, referred to as the Yukon-Northwest Seismograph Network (YNSN). In particular, this grant will support expensive annual visits to seismograph station sites accessible by roads and airplanes during peak weather conditions in the summer period. Data provided by the YNSN network will be used to investigate crust and mantle structure beneath the Cordillera and to improve earthquake characterization and tectonic deformation. In particular, the near real-time data transmission will be extremely important for the rapid assessment and dissemination of earthquake information, valuable to local northern communities as well as the mining and petroleum sectors. Importantly, the project will provide unique opportunities for training of highly qualified personnel in all aspects of observational seismology, from site installation to data analysis, throughout the duration of the project. The project also seeks to increase awareness of local communities to Earth Sciences by installing a seismograph station on a school ground wherever possible and by engaging teachers in using the infrastructure as an educational tool.

加拿大北方科迪勒拉山脉包括育空地区和西北地区西部，是观测地震学研究的理想天然实验室，因为该大陆这一部分的构造结构和地震活动丰富多样（每年约130次3级以上地震）。不幸的是，加拿大国家地震仪网络目前的地震仪器覆盖范围远远不足以进行更密集的网络所能提供的地震学变革性研究。因此，本提案寻求资金，以支持与在育空地区和西北地区安装和维护一个由10个最先进的宽带地震仪台站组成的区域网络有关的研究活动，该网络被称为育空-西北地震仪网络。特别是，这笔赠款将支持在夏季天气高峰期间，对可通过公路和飞机到达的地震台站进行昂贵的年度访问。 YNSN网络提供的数据将用于调查科迪勒拉山脉下的地壳和地幔结构，并改进地震特征和构造变形。特别是，近实时数据传输对于迅速评估和传播地震信息极为重要，对当地北方社区以及采矿和石油部门都很有价值。重要的是，该项目将提供独特的机会，在整个项目期间培训观测地震学所有方面的高素质人员，从现场安装到数据分析。该项目还力求提高当地社区对地球科学的认识，尽可能在学校场地安装地震仪站，并让教师利用基础设施作为教育工具。
