[CEUS-earthquake-hazards] Fall AGU session T10: Rifts and Basins of the US Interior: A New Earthscope Frontier

[Maria Beatrice Magnani (mmagnani)]

Dear Colleagues,

We'd like to invite you to contribute to the session "T10: Rifts and Basins of the US Interior: A New Earthscope Frontier" to be held at the Fall AGU meeting in San Francisco, 14-18 December, 2009.

Description: 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.

Sponsor: Tectonophysics
CoSponsor: Seismology, Geomagnetism and Paleomagnetism
