Fig. 2From: Regional electrical structure of the Andean subduction zone in central Chile (35°–36°S) using magnetotelluricsProfile showing skew values according to Bahr (1988). Each column represents an interpolation of the skew value between two sites. The width of the columns considers the spacing between the sites along the profile, resulting in a more detailed image of this parameter to the East. Low skew (< 0.3) indicates relatively 2D structureBack to article page
