Abstract: Flat-slab subduction is often proposed to cause deformation of continental crust far from plate boundaries as well as unusual patterns of volcanism; a study of the largest-known flat slab, located in Peru, now shows that the ridge is necessary for the formation and longevity of the flat slab, whereas other contributing factors such as trench retreat and suction alone will not suffice.
