In the paper “Current deformation rates and extrusion of the northwestern Okhotsk plate, northeast Russia” by D. Hindle et al. (Geophysical Research Letters, 33, L02306, doi:10.1029/2005GL024814, 2006), because of an error in a subroutine, the strain rates calculated from the pure contraction and smooth extrusion models and from GPS data should be corrected according to Table 1. All other data, including the seismic strain rate, and all velocities from the models remain the same. Figure 3 is redrafted with the corrected strain rate axes. The corrected model strain rates (∼5.0 × 10−9 yr −1) and orientations (∼062°) nevertheless remain broadly the same. Both principal axes from the pure contraction model are compressional, whilst the largest principal strain rate component in the smooth extrusion model is contractional. The principal strain rates from GPS data are slightly higher, with the orientation of the contractional strain component (∼085°) broadly comparable to model results and seismic strain.
