A range of stress sources contribute to the stress state of the lithosphere (e.g. Ranalli, 1995): slab pull, shear resistance at subduction zones and strike slip faults, convection drag at the base of the lithosphere, stresses transferred to the interior of plates from plate boundary processes, horizontal gradients of pressure variations at the base of the lithosphere (“dynamic topography”) and horizontal gradients of lithospheric potential energy.
