From: Three-dimensional inversion of magnetotelluric data from the Central Andean continental margin
3-D model (RMS = 1.79) of area B inverted with WSINV3DMT. Background resistivity set to 100 Ωm. (a) Plan view at a depth of 3.20 km. E, conductive structure correlating with fumarolic activity of Olca volcano (triangle). (b) Same model at a depth of 12.79 km. F and G, mark elongated shapes of the West Fissure; H, resistive Western Cordillera. (c) Lower image: S-N transect with depth along the West Fissure. Plate boundary is at approximately 90 km deep (Yoon et al.2009).
