Figure 6.

A. YZI after glacial unloading in the faulted model, the YZI strain increment is high in the Yakutat Bay region.

B. The locations of the 1899 earthquakes in Yakutat Bay and the contours of vertical velocity (mm/yr) due to glacial isostasy of the LIA. Velocity vectors are the horizontal velocities associated with isostatic rebound (modified from Plafker and Thatcher 2008; Elliott et al. 2010). Dashed lines mark the location of the Transition fault, subduction zone, and Fairweather fault boundaries, solid black line marks the modern coast of Alaska.
