a Three-dimensional isotropic/anisotropic model adapted from the 2-D model of Pek et al. (2008) for the case where the 3-D body is buried at a depth of 5 km. b Plane view at a depth of 5 km. c Cross-section along west–east direction (y-axis). The two isotropic 300 Ω-m and 1000 Ω-m layers are kept fixed. Only the 3-D body will be changed to either anisotropic or isotropic resistivity with various resistivity values. The 3-D body was buried at various depths: 0 km (surface), 5 km (shown above), and 20 km. Dots at the surface on b are the 484 MT stations used in this study. Scenter, Sedge, and Souter are the stations discussed in the next section
