Horizontal sections of the optimal 3-D model for different five elevations (2000, 1800, 1600, 1400, and 1200 m). The topographic map is shown in the top left panel with the AMT sites (blue dots). The locations of the vertical east–west section shown in Figs. 6a, 7a, and 8 and the north–south section shown in Fig. 9 are indicated by the green and orange lines. Red triangles represent the 2018 craters (MC, WC, and SC). Gray dots in each section represent the AMT sites. The resistive feature near the surface is labeled R1, the conductive features are labeled C1 and the relatively resistive region around C1 is labeled R2. The white dashed line represents the crack model proposed by Terada et al. (2021). Black dots represent volcanic tremors just before the 2018 eruption, as suggested by Yamada et al. (2021)
