Figure 2. Overview of the geodetic coupling model and plate boundary context along the AASZ. Calculation of relative Pacific-Arc Observed (Pac-Arc OBS) velocities is described in the text. Sections as in Figure 1. Bering Plate boundary approximation from Mackey et al. (1997). Slab interface contours are from Hayes et al. (2018). Bathymetry and shaded relief from GEBCO Compilation Group (2023).
