Seismic-gravimetric analysis of the subducted Nazca plate 1 between 32°S and 36°S
The study region is seismically and tectonically characterized by the angle variations in the subduction of the Nazca plate. The results obtained from earthquakes location between 32° and 36°S latitude and 67°–71°W longitude are presented in this work. The presence of a wedge of asthenospheric mater...

| Sumario: | The study region is seismically and tectonically characterized by the angle variations in the subduction of the Nazca plate. The results obtained from earthquakes location between 32° and 36°S latitude and 67°–71°W longitude are presented in this work. The presence of a wedge of asthenospheric materials and the partial or total eclogitization of the subducted Nazca plate and its relation with isostatic cortex models published was analyzed. In addition, a gravimetric profile obtained from gravity forward modeling is presented at 33.5°S, proposing a new configuration at depths for the main tectonic components: Nazca plate, asthenospheric wedge and South American plate. Also, a new density scheme using recently published velocity models was obtained. |
