Extended Data Fig. 5: Synthetic test for estimating model resolution for the case of increased Vp/Vs plate boundary zone.
From: Correlation of porosity variations and rheological transitions on the southern Cascadia megathrust
(a–d) True (a, c) and recovered (b, d) Vs perturbation model (a, b) and Vp/Vs model (c, d) at the cross-sections of AA’-EE’. (e, f) Map view of the true and recovered Vp/Vs models of the plate boundary zone. The true model contains a 6-km-thick, low Vs, and high Vp/Vs layer below the plate interface.
