Abstract Lithospheric plates bend at subduction zones where the vertical motions of the slabs are converted to surface plate motions. To understand the mechanics of plate bending we derive scaling laws for the deflection at the margin, i.e. radius and dip, from numerical models of a subducting viscoelastic plate. In such dynamic system we find that the buoyancy and the stiffness of the plates control the radius and the dip, as well as the plate motions toward the trench. This mechanical model… CONTINUE READING
