This PDF file includes:

  • Supplementary Materials and Methods
  • Fig. S1. Continuous GPS network and interpolated interseismic velocity.
  • Fig. S2. CGPS time series, empirical fits, and afterslip and viscoelastic flow modeling–based time series (also see subsequent pages).
  • Fig. S3. Inversion parameters and sensitivity tests for select volumes.
  • Fig. S4. Five checkerboard tests for slip on the megathrust and strain in the polyhedral volumes, which demonstrate our ability to resolve any up- and down-dip slip and viscous strain in the ductile region using our CGPS site distribution (white triangles).
  • Fig. S5. Sensitivity tests for refining the model geometry.
  • Fig. S6. Resolution power of strain components for each deformable finite volume.
  • Fig. S7. Afterslip-related test and parameters for fault friction estimates.
  • Fig. S8. Cross sections of derived rheological and thermal parameters from inversion and flow law modeling.
  • Fig. S9. 3D, stress-driven, postseismic forward models of frictional afterslip and viscoelstic flow for comparison with inversion results.
  • Table S1. Dislocation creep rheological parameter estimates for the Maule region.
  • Table S2. Temperature estimates for the polyhedra.
