Isnt it a little different? The area threatened by tsunami maybe be less than a mile from the coast. If there's a nearby hill, less. It should not be a tremendous burden to keep your hospital a mile inland, or a hundred feet up the hill. Those who choose to live in the area can make a plan to briskly walk uphill when they feel tremors or hear sirens. The area threatened by a major earthquake may extend for hundreds of miles and elevation is no defense. We have no choice but to locate public facilities in that area.
