Fig. 4

Horizontal sections of the final 3-D resistivity model for six different elevations. Horizontal sections of resistivity for elevations of 1200, 1000, 800, 600, 300, and 0 m. The dashed line in each diagram indicates the projection of the outline of the Nakadake crater system. The solid line shown in the diagrams for 800, 600, 300, and 0 m represents the intersection of each section with the crack-like conduit reported by Yamamoto et al. (1999). The red circles indicate AMT sites
