- •
Vertical gravity gradient show a deflection of the main Andean structures trend.
- •
Relationship between the Copiapo ridge and deformation in the upper plate.
- •
The Copiapo ridge controls the northern edge of the Chilean flat subduction zone.
- •
Leading to shallower subduction at the northern region of the Chilean flat-slab.
- •
Chilean-Pampean flat slab could be related to two simultaneous ridge collision.
