It is interesting to notice that all scenarios show concentration of energy in Central Oregon. This is a consequence of a combination of quite distinctive local topographic features: Heceta Valley, Perpetua Bank, and Stonewall Bank.
Also interesting is that the patterns of propagation in the Oregon/Washington border are qualitatively similar for the two scenarios where significant subsidence occurs offshore (Scenarios 1 and 2), both of which lead to large regions of energy concentarion. Scenarios 3 and 4 (where significant subsidence occurs only closer to the shore) do not show the same pattern, though.
