ChinArray and USArray: Design, Success, and Challenges
Session ID#: 76799
Session Description:
China and the contiguous United States have some similarities in size and in having more tectonic activity in the west; they also have some differences in how the lithosphere of these two nations was created. These similarities and differences can be revealed by comparing their crust and mantle structures. The ongoing ChinArray and the almost-completed USArray are providing images of unprecedented spatial coverage and resolution, which can be interpreted to provide important perspectives on crustal and mantle structure beneath these two areas. This session will compare the design and data management of both arrays, explore what has been learned on the spatial-temporal distribution of earthquakes, velocity structure, layering, and azimuthal and radial anisotropies of the crust and mantle using the unique data sets, and facilitate collaborative studies among Chinese and American scientists.
