Figure 3From: Three-dimensional electromagnetic imaging of fluids and melts beneath the NE Japan arc revisited by using geomagnetic transfer function dataInitial model of the 3-D inversion. The resistivity structure of the Earth was a uniform-half space with a resistivity of 100 Ωm; resistivity blocks corresponding to seawater were fixed at 0.33 Ωm. Resistivities of blocks containing the land-sea boundary were given as the weighted mean of two values, according to the volume ratio.Back to article page
