Seismic Velocity Structure in the Area of the 2007, Mw 8.0, Pisco-Peru Earthquake: Implications for the Mechanics of Subduction in the Vicinity of the Nazca Ridge

<div>Aftershock distribution map for the Pisco earthquake registered from December 2007 to May 2008. The large red star corresponds to the main event epicenter, whereas the small star corresponds to the large aftershock. (a) Preliminary aftershock distribution map using the 1D velocity model [<a href="/journals/ijge/2020/3874524/#B12">12</a>] and its respective seismic profile A-A’. (b) Relocated aftershock distribution map using the 3D velocity model (TomoDD), and its respective seismic profile B-B’. The map presents the 15 km grid that was used on the inversion process to obtain the 3D velocity model and aftershock relocation.</div>
