TS7.2/GD5.6/GMPV24/SM6.8On and through the plate interface: zooming into subduction zone processes (co-sponsored by AGU-Tectonophysics) (co-organized)

Subduction zone processes are controlled by the mechanical coupling and global material transfer at and across subduction zone inter-plate boundaries, between the down-going subducting plate and the overriding plate. Although stresses and energy release via earthquakes together with fluid-mediated mass transfer largely concentrate on the plate interface, interacting on a wide range of spatial and temporal scales, the nature, structure and physical properties of this interface remain badly unknown.
We welcome all contributions dealing with the subduction interface, in particular cross-disciplinary data and models providing (1) high-resolution images of the plate interface and constraints on (2) plate interface rheology through space & time (from seconds to million years) and (3) fluxes of fluid and mass along & across the interface.
