EarthScope is a major science initiative in the solid-earth sciences and has been described as "a new earth science initiative that will dramatically advance our physical understanding of the North American continent by exploring its three-dimensional structure through time". The initiative proposes to cover the United States with an array of instruments created to reveal how the continent was put together, how the continent is moving now, and what lies beneath the continent. The initiative is made of four components, three of which are funded by the Major Research Equipment program of the National Science Foundation (NSF) and one of which is mostly associated with the National Aeronautics a...
