The elevation of Ocean Village has been determined in order to predict the potential risk to tsunamis, but why might this elevation not be accurate after a tsunami?
Ocean Village could be located above a subduction zone. After strain is released at a subduction zone, land elevation lowers. Therefore, more areas may be affected by a tsunami.
Which has the potential for greater run-up: a category 5 hurricane or a tsunami generated by a large earthquake?
It is impossible to tell; there are other factors to consider.
