In order to provide new regional-scale information on the internal structure of the eastern Canadian Shield, it is vital to deploy new broadband seismograph stations across Quebec. The resolution of crust and upper mantle seismic structure in the region has been greatly impeded by a lack of seismograph station coverage, and broadband sensors are essential in obtaining the full range of seismic data necessary to achieve this goal. The primary target for seismic studies in the 2007-2009 time period is the Abitibi Greenstone Belt and the neighbouring western Grenville Province, which straddle the Ontario-Quebec border. Recent studies across northern Ontario, along with previous 2-D studies, suggest that the continental crust and mantle beneath this region is extremely complex. In order to resolve 3-D structure, the deployment of ten new broadband seismograph stations in western Quebec is required, to add to the existing station coverage in eastern Ontario. The stations will use internet connections to provide real-time seismic data for the project.

为了提供关于加拿大东部地盾内部结构的新的区域尺度信息，在魁北克部署新的宽带地震仪站是至关重要的。由于地震台台站覆盖不足，该地区地壳和上地幔地震结构的分辨率受到了很大的阻碍，而宽带传感器对于获得实现这一目标所需的全范围地震数据至关重要。2007-2009年期间地震研究的主要目标是横跨安大略省和魁北克省边界的阿比提比绿岩带和邻近的格伦维尔省西部。最近对安大略省北部的研究，以及之前的二维研究表明，该地区的大陆地壳和地幔极其复杂。为了解决三维结构问题，需要在魁北克西部部署10个新的宽带地震仪站，以增加安大略省东部现有站点的覆盖范围。这些监测站将利用互联网连接为该项目提供实时地震数据。
