Geodetic analysis of crustal deformation, active tectonics and sea-level rise hazards in Western Canada

在过去十年中，高精度大地测量提供了重要的新成果，大大提高了我们对加拿大和世界各地活动构造和自然灾害的理解。根据我们在这些领域的丰富经验，本建议的目标是整合和联合收割机大地测量和遥感数据，以更好地了解加拿大西部的地壳变形和地球动力学并建立模型。我们将进行和联合收割机大地测量，如绝对重力，全球定位系统（GPS），雷达干涉测量（干涉合成孔径雷达），以产生高精度和高精度的估计，在加拿大西部的现今地壳变形。这些数据对于了解加拿大科迪勒拉和加拿大西部板块边界的地球动力学至关重要。这些结果将用于限制地震和相对海平面上升的危害评估。特别是，垂直陆地运动是估计未来相对海平面的关键因素。本提案的预算将主要用于支持研究生和本科生合作学生，并在很小程度上支持在选定的全球定位系统和绝对重力站点进行实地测量。

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.
