Fig. 3

Apparent resistivity distributions calculated using the rotational invariant \(\mathrm{det}(Re \mathbf{Z})\) (the determinant of the real part of impedance \(\mathbf{Z}\)) for four representative frequencies (5200, 635, 45, and 5.6 Hz). Black dots show the AMT sites. The three red triangles represent the craters of the 2018 eruption (MC, WC, and SC in Fig. 2). Red dotted circles represent the Kagamiike-kita Crater and the Kagamiike Crater
