Sensitivity test of the optimal 3-D resistivity structure model. a The east–west vertical cross-section through the Kagamiike-kita Crater of the optimal model is shown. The sensitivity of the region surrounded by the white solid line was tested. The size of the modified region was 0.6 km (N-S) by 0.5 km (E-W) by 0.6 km (vertical). b Sounding curves (apparent resistivity and phase) obtained from the optimal model (green), modified model (blue), and observed data (open circles with red error bars) at Site 15 directly above the modified region are shown
