Horizontal sections of the final resistivity model obtained from 3D inversion at a 4.25–5.00 km, b 5.00–6.00 km, c 6.00–7.00 km, d 7.00–8.00 km, e 8.00–9.00 km, and f 9.00–10.00 km below sea level. Black circles show the epicenters of earthquakes at the corresponding depths detected by JMA from January 1983 to March 2016, and red circles show the epicenters of aftershocks of the 2016 Kumamoto Earthquake from April 2016 to September 2016. Black triangles indicate the five main post-caldera cones. The red star in (a) indicates the position of the source of deformation at 5 km BSL detected by Ohkura and Oikawa (2012). In the color scale, the value of 30 Ωm is indicated by an arrow because the plastic region has a resistivity of < 30 Ωm (see text)
