Figure 2: (Top) Map of the tectonic setting with variously reported focal mechanisms (beachballs), which illustrate either the interpreted initiation point of the earthquake (origin method) or the interpreted center of moment release (centroid method). Colored contours represent depth of slab2.0 (Hayes, 2018). (Bottom) The five profiles are aligned along the 40-km depth contour of the slab, and show that the reported locations broadly vary from above to below the slab, and from deep to shallow. Map produced using tectoplot (Bradley, 2021).
