The article is a bit panicky. As the writer puts it, the worst cast scenario is what will definetly happen. With the epicenter being probably 100 miles off the coast, when the big one comes the worst will probably not happen.
Of course, even if the worst case does not happen, the coast will still probably be devastated. I can see where all of the magnificent old bridges on Hwy 101 could come down, and then the only routes into the coastal towns would be from far inland.
Most Oregon coastal towns are not all that vulnerable to tsunamis. There is low-lying ground, but not that much, and high ground is mostly nearby. The biggest dangers from tsunamis, I think, are in the inland estuaries and bays. Waldport, Newport, Reedsport, Coos Bay and inland from Florence come to mind.
THe second pic on link is the Bay Rd. that is about 20-25 ft. below our property.

The second and third pic show the hill down to the Bay Rd. and the Bay Road itself in the third pic is the photo view of the curve on the earlier post of the man's skull chart of the bay.
