Misfit between the sea surface height of full-physics simulations and shallow water simulations, calculated at the final time step plotted in previous figures using the \(L_2\) norm. a Misfits for the idealized structure in Fig. 3, calculated at \(t=600\) s as in Fig. 5. b Misfits for the Tohoku geometry in Fig. 6, calculated at \(t=500\) s as in Fig. 7. For both sets of simulations and both choices of \(L_H\), misfit is minimized as rise time \(\tau\) approaches infinity (initial velocity \(v_0 \rightarrow 0\))
