Extended Data Fig. 1: The impact of variable crustal viscosity on the horizontal deviatoric normal stress (x-direction) in single slab models, double slab models and the difference between single and double slab cases.
From: Non-collisional orogeny in northeast Japan driven by nearby same-dip double subduction
Crust viscosities tested are 1019 Pas a, 5 × 1019 Pas b, 2.5 × 1020 Pas c, and 1021 Pas d. All other parameter values are held constant, including the lithosphere-mantle viscosity ratio of 500. The crust viscosity of panel b (5 x 10 19 Pas) is equivalent to that within the reference models presented in the main text. However, unlike in the reference models, the power-law mantle viscosity component is turned off in this suite of models. Abbreviations are: PSP: Philippine Sea Plate and PAC: Pacific Plate.
