Hypocenters of earthquakes shallower than 5 km depth (white dots) superimposed on the S-wave velocity structure. a, c Rayleigh wave results. b, d Love wave results. Depth is shown above the upper left corner. Hypocenters of earthquakes with moment magnitude > 1 occurring during 1983–2016 are shown. Green triangle shows the Mt. Sanbe
