Extended Data Fig. 7: Megathrust interseismic coupling models.
From: Correlation of porosity variations and rheological transitions on the southern Cascadia megathrust
(a–c) Interseismic coupling models calculated with different mantle viscosity values (a, 4.4 × 1018 Pa s; b, 4.0 × 1019 Pa s; c, 3.6 × 1020 Pa s), from ref. 6. Curves in the panels below map views show downdip variations in megathrust locking ratio along BB’, CC’, and DD’ and are colored by the Vp/Vs value of plate boundary zone. All the other elements in map views are the same as Fig. 3a, except that the LFEs are shown as orange dots.
