Fig. 6From: Analysis of plate spin motion and its implications for strength of plate boundaryThe driving shear stress along a plate boundary \(\sigma _{PB}\) obtained from Eq. (5) as a function of plate size (=2R). The symbols and error bars are the same as in Fig. 5. The dashed line is the expected driving stress induced by the motion of the Pacific plate (corresponding to the dashed line in Fig. 5)Back to article page
