Non-planar fault model and snapshots of the distribution of high-frequency radiation of the Mw 8.8 2010 Chile earthquake obtained by the HBP method.
(a) The geometry of the non-planar fault model. (b) Snapshots of spatiotemporal distribution of high-frequency radiation obtained by the HBP method. The color scale represents normalized amplitudes and warmer colors show relatively stronger high-frequency radiation. The star indicates the epicentre of the 2010 Chile earthquake determined by CSN. The dashed line and white lines are the trench location and the coastline, respectively. The distribution of average slip-rate within the corresponding time period is overlaid on the HBP result in (b) as white contours (contour intervals, 0.07 m/s).
