In the deep ocean, their length from wave crest to wave crest may be a hundred miles or more but with a wave height of only a few feet or less. But as the tsunami approaches shore, friction with the continental shelf in shallow water slows the tsunami's front. Trailing waves pile up, pushing the height of the onrushing wave to 30 feet or more. Although slowed, a tsunami plows onto land at freeway speeds, with enough momentum to flatten buildings and trees and to carry ships miles inland.
