Self-similarity in the seismicity of the South-American subduction zone

Mostrar todas las versiones(2)

The spatial distribution of hypocenters corresponding to intermediate and deep seismicity along the South-American subduction zone has led to a description of the geometry of this subduction process. Changes in the angle of subduction have been detected, which led to a division of the subducted regi...
