We encourage you to move your research to the continental interior,  
along with USArray, and submit your AGU abstract to session T10!

T10  RIFTS AND BASINS OF THE US INTERIOR: A NEW EARTHSCOPE FRONTIER
The arrival of Earthscope's USArray in the US continental interior  
offers an unrivaled opportunity to study the lithospheric structure  
of a plate interior and to examine non-plate boundary processes. In  
the interior of North America, dramatic structures are preserved that  
include major failed rifts, large intracratonic basins, and  
reactivation structures with km-scale vertical movements that  
collectively demonstrate significant, localized plate deformation  
away from plate boundaries. The presence of (reactivated) rifts and  
basins remains difficult to reconcile with arguments for stable,  
rigid plates as the foundation of plate tectonic theory. This session  
will examine major intraplate structures and targeted seismological  
experiments to image the crust and upper mantle of today's North  
American plate interior. Contributors are encouraged to contrast  
hypotheses on the origin and evolution of intraplate structures and  
to examine the insights that can be gained from new seismo-tectonic  
experiments and complementary field, laboratory and modeling studies.

We also welcome abstracts addressing the North American Plate in its  
entirety.
