.... The Farallón Negro Volcanic Complex is located in a transect centered at latitude 27° S, which overlies a north to south transition in the configuration of the Wadati-Benioff zone from steeply (ca. 30°) to shallowly dipping ( Isacks, 1988 ; Fig. 1 ). The emplacement of voluminous subduction-related magmas...
