In the last decade, high-precision geodetic measurements have provided crucial new results that have dramatically improved our understanding of active tectonics and natural hazards in Canada and worldwide. Building on our strong experience in these fields, the goal of this proposal is to integrate and combine geodetic and remote sensing data to better understand and model crustal deformation and geodynamics of western Canada. We will carry out and combine geodetic measurements such as absolute gravity, Global Positioning System (GPS), and Radar interferometry (InSAR), to produce high-precision and high-accuracy estimates of present-day crustal deformation in western Canada. These data are essential to understand the geodynamics of the Canadian Cordillera and western Canada plate boundaries. These results will be used to constrain hazard assessment from earthquakes and relative sea-level rise. In particular, vertical land motion is a crucial factor in estimates of future relative sea level. The budget for this proposal will be used in majority to support graduate students and under-graduate coop students, and to a small extent to support field measurements at selected GPS and absolute gravity sites.
