**6. Evaluation of radar sites for tsunami detection using simulated tsunami velocities**

As some sites are less suitable than others for tsunami monitoring with coastal radar systems, we are developing a site‐dependent method that uses simulated tsunami velocities to estimate the size of a tsunami required to trigger a detection as a function of distance from the shore. This leads to an estimate of the warning time available. The tsunami simulation methods currently available have been discussed in the previous section. Tsunami simulation based on PDE model solutions of equations of motion is under development at this time with early results discussed in Section 5.1. As it does not yet produce actual (non‐normalized) heights and velocities, as an interim measure, we use the approximate simulated velocities based on Green's Law described in Section 5.2.
