  1. aIn the model names, “Hom.” indicates a homogeneous model, “EL” indicates a linear elastic model, “EP” indicates an elastoplastic model, “CZ” indicates a model with a compliant zone, “Layered” indicates a model with lithologic layering of the identified parameters, “Het.” indicates a model with both a compliant zone and lithologic layering.
  2. bE is Young’s modulus, ν is Poisson’s ratio, C is cohesion, ϕ is the angle of internal friction, and Ψ is the dilation angle. Subscripts “b” and “s” and superscript “cz” designate basement unit, surface unit, and compliant zone, respectively (Supplementary Fig. 2).
