I Live about 150 Feet above Sea Level

Does that mean I'm off the hook?

Through a combination of computer simulations and observations at New Guinea and other sites of previous, smaller tsunamis, Day and colleague Steven Ward of the University of California, Santa Cruz, predicted that waves up to 200 feet high could crash into the Saharan coast in Africa. They predict it would take about eight hours for the tsunami to travel westward across the ocean, after which waves more than 60 feet high could flood all major eastern cities from Boston to Miami, penetrating up to 15 miles inland.

On the other hand, I think I'm closer than 15 miles to the ocean, but I suspect that's an important figure only in very flat areas.
