Non-planar fault model and snapshots of the distribution of high-frequency radiation of the Mw 7.1 2012 Chile earthquake obtained by the HBP and BP methods.
(a) The geometry of the non-planar fault model. Snapshots of spatiotemporal distribution of high-frequency radiation obtained by (b) the HBP method and (c) the BP method. The color scale represents normalized amplitudes and warmer colors show relatively stronger high-frequency radiation. The star indicates the epicentre of the 2012 Chile earthquake determined by CSN. The dashed line and white lines are the trench location and the coastline, respectively.
