Example acceleration recordings and S-wave time windows (red portions) selected for evaluation of nonlinear site response at site IBUH01. a Recordings from an event that occurred on Nov 1, 2006, at 23:21 JST (Mj = 4.8, focal depth = 49 km, epicentral distance = 123 km, back azimuth = 120°). b Recordings from mainshock. The borehole and surface recordings are plotted in left and right panels, respectively. The north–south (NS), east–west (EW), and vertical (UD) components are indicated in each panel. Note that the scale of the vertical axis for surface recordings (right panels) is larger by a factor of 10 with respect to that for borehole recordings. The recordings for the mainshock are shifted to the right by 4 s to match with the S-wave arrivals on the weak-motion recordings in panel a
