GPS measurements of continental deformation have traditionally been used for kinematics, the quantification of what moves where and how fast.  However, with more sophisticated processing techniques, better data, and enhanced interpretation, the same data can be used to address basic earth science questions over a range of spatial and temporal scales.  For example, at the largest scales, GPS data may constrain the rheology and structural architecture of continental lithosphere.  At intermediate scales, GPS data may constrain the rheology and architecture of the crust, or the physics of earthquake ruptures.  At the shortest scales, especially in time, GPS data may constrain weather and climate phenomena, especially the interaction of seasonal precipitation patterns with the solid earth.
