P-wave velocity structure and relocated hypocenters in this study. a Surface geology and velocity structure at b 2.5 km, c 5 km, d 7.5 km, e 10 km, and f 12.5 km depth. The white circles indicate the relocated hypocenters within 2.5 km of each depth slice. The solid and dashed red lines denote the active faults determined by RGAF (1991) and HERP (2013), respectively. BSG Beppu–Shimabara Graben, UYTL Usuki–Yatsushiro Tectonic Line, FT Futagawa segment, UT Uto segment, UN north coast of Uto Peninsula segment, TS Takano–Shirahata segment, HN Hinagu segment. The geological classification in a is the same as in Fig. 1. L0–L4 and H0–H4 denote velocity anomalies (patches) that are discussed in the text. The southern termination of the fault rupture, which is estimated during our study, is indicated by the black arrow
