As a tsunami reaches the shallow water near a coastline, its speed decreases, but as the wave compresses it may grow to a height of 20 feet to 30 feet or more. Tsunami speed can be computed by taking the square root of the product of the acceleration of gravity, which is 32.2 feet (9.8 meters) per second squared, and water depth. As the waves enter shallow water near land, they slow to the speed of a car, approximately 20 or 30 mph.
