a, b S-wave velocity structure at 1 km and 9 km depths below sea level, and c–f vertical S-wave velocity sections beneath the profiles marked in panel a, showing the variation of S-wave velocity with depth (bottom panels) and their respective elevation models in km (top panels). The solid black line represents the Median Tectonic Line (MTL), the dashed red closed-curve represents the Niigata–Kobe Tectonic Zone (NKTZ), and the thick solid blue line indicates the location of the Arima-Takatsuki Tectonic Line (ATTL). Black triangle represents the location of Hokusetsu mountains. Thin, dashed black closed-curves show the locations of major sedimentary basins (SB, Sanda basin; FB, Fukuchiyama basin; OB, Osaka basin; NB, Nara basin; OoB, Oomi basin; KB, Kyoto basin; and IB, Ise basin). Also shown on the depth slices are the probable locations of the Kawachi plain, Nara basin (NB), Uemachi Fault Zone (UFZ), Ikoma Fault Zone (IFZ), Biwako-seigan Fault Zone (BSFZ), NKTZ, Osaka basin (OB), and Ise basin (IB)
