Extended Data Fig. 5: Analytical force balance model.
From: Megathrust shear force controls mountain height at convergent plate margins
a, b, Schematic illustration of the force balance model for subduction and collision zones, respectively. Fs is the shear force along the megathrust and Fg is the gravitational force. \(\bar{\rho }\) is the average density of the triangular wedge above the megathrust. P is the push of the upper plate. L is the downdip extent of the megathrust. dT is the trench depth and γ is the surface slope of the submarine part of the wedge. See Methods and refs. 2,3 for details.
