Fig. 5: Predicted crustal deformation and stress due to different driving forces.
From: Western US intraplate deformation controlled by the complex lithospheric structure
Predicted crustal deformation rate and crustal stress in the uppermost 30 km from a M4 with LTM1, a 3D lithospheric effective viscosity structure, and a none convective mantle, b M5 with a lithosphere the same as M4 and all density anomalies in the convective mantle, c M6 with LTM1, a 3D lithospheric effective viscosity structure, all density anomalies in the lithosphere, and a none convective mantle. Comparisons between the GPS-measured surface motion and predicted surface motion from d M4, e M5, and f M6. In (a)–(c), the bars show the directions and magnitudes of horizontal principal stresses, with red representing compression and green representing extension. In (a)–(c), the orange dashed line marks the location of LAB at 75 km, approximating the lithospheric thickness step in LTM1. In (d)–(f), the black bars represent the smoothed GPS measurements, and the magenta bars represent the predictions.
