How long the water would remain on the land depends entirely on the altitude and lay of the land. Meanwhile, by allowing police stations and firehouses to be built within the inundation zone, Oregon is directly endangering the people tasked with showing up when disaster strikesand, in doing so, doubly abandoning everyone else to their fate. Much work is presently under way by seismologists to determine the nature of earthquake rupture along major plate boundary faults.

The local tsunami that is generated from this rupture is shown below as a synthetic marigram (wave amplitude as a function of time). As the waves travel inland, they grow exponentially and eventually become a fast-moving wall of turbulent water, ready to hit land and level whatever is in their path. There is considerably less scatter in the scaling relationship for distant tsunamis because of the smoothing effect of tsunami propagation on small-scale variations of the earthquake rupture process. The only public testimony came from the members of the Oregon Legislative Coastal Caucus, all but one of whom supported repealing the law. However daunting the price tag on doing so might seem now, it pales in comparison to how much it will cost to not have done so by the time catastrophe strikes. except with the prior written permission of Oregon Live LLC.

Effects can be long-lasting, and felt far beyond the coastline. Fault C, shown in the second set of figures, ruptures much shallower in the earth and generates a substantially larger tsunami. The same goes for putting hospitals in the inundation zone: in addition to gravely endangering all the patients, family members, and employees who are in them when the tsunami strikes, it means that, after the ground has stopped shaking and the water has receded, there will be no functioning medical facility to receive the injured and no advanced medical equipment on hand to help save lives.
