a West–east cross-section at X = – 5 km for the inverted model. The cross-hatched area shows the low-sensitivity area within the C-2 anomaly. The red dashed line marks the SSE fault plane inferred by Ohzono et al. (2015). The other symbols are the same as in Fig. 3. b Geological interpretation of the inverted model at X = – 5 km. The pink area with red arrows represents the uplifting serpentinite complex and associated fluids, and includes the C-2 anomaly, the surface conductive area, and the high resistivity area sandwiched between them
