The overriding-objective of this project is to use Earthscope data to determine a high-precision, high resolution, four-dimensional image of crustal deformation for the North America continent on time-scales of days to decades, and spatial-scales of kilometers to thousands of kilometers. This goal will be achieved by analyzing continuous GPS data from Earthscope's Plate Boundary Observatory (PBO) facility, and by expanding upon past experience in the analysis and modeling of plate boundary-scale crustal deformations to better account for time-dependence of crustal motions. The fundamental objective of developing methods to realize four-dimensional solutions of the velocity gradient tensor field will be achieved prior to the full implementation of Earthscope. It is a primary goal to develop a tool that the community can use for future analysis of Earthscope data as the project matures.

该项目的压倒性对象是使用地球数据来确定北美大陆上的高精度，高分辨率，四维的地壳变形图像，以数十年的时间尺度和数十年的时间尺度，以及公里的空间量表至数千公里。 通过分析来自Earthscope板边界观测站（PBO）设施的连续GPS数据，以及扩展板板边界尺度的地壳变形和建模的过去经验，以更好地说明地壳运动的时间依赖性，可以实现此目标。 开发方法的基本目标将在全面实施EarthScope之前实现速度梯度张量场的四维解决方案。 这是开发一种工具的主要目标，该工具可以随着项目的成熟而将其用于将来对Earthscope数据进行分析。
