Extrait: 

The notion that erosion and sedimentation help localize strain at tectonic plate boundaries is now backed up by two decades of numerical modeling. Key questions however remain regarding: (1) the physics that underlie this important feedback; (2) the main parameters that make a tectonic system sensitive to surficial mass redistribution; and (3) whether this feedback can be documented in real settings. I will address these issues through the perspective of extensional plate boundaries, using a variety of examples from continental rifts to mid-ocean ridges.
