In the western part of the central Chile-western Argentina, the Nazca plate is subducting under thecontinental south American plate. Toward the North of 33°S, where the slab become flat at 100km depth,the Juan Fernandez ridge is subducting under the Nazca plate. This region is a transition zone between aflat and a dipped slab. Though the quaternary volcanic activity stop between 5-7 My, toward the Southof 33°S where the slab dip is 30°most of the volcanic buildings are still active at that period. Using localearthquakes recorded from seismological campaign, we realized a delay travel time and an attenuationparameter (t*=t/Q) tomography in order to determine a 3D velocity model and a 3D model for attenuation.These two Tomographic models have...
