A geologic incident on the ocean floor, at a depth of thousands of meters, causes part of the ocean floor to sink or rise. A shock wave creates enormous waves that move at a velocity of 600 to 800 km/h. This velocity is proportional to the depth and diminishes as the tsunami nears the coast, the gradual upward slope of the ocean floor increases the height of the waves. When the ocean floor becomes shallow, the swell is deformed, the waves slow to about 50 km/h, but their height grows considerably. Finally, these giant waves break on the shore. | |
