Induction vectors plotted under the convention of Wiese (1962), the arrows point in the opposite direction of the conductive zone. The vectors enclosed in the yellow box indicate an anisotropic electrical behavior in the crust, the vectors enclosed by the light blue and green zones, because of their magnitude, could indicate data that are within a conductive body and the vectors enclosed in the purple zone indicate a strong conductor to the west area of the profile, the arrows enclosed by the pink line would be related to a conductor in the Osorno volcano
