- The Science Behind Tsunamis: What You Need to Know
The result is a wave that can travel at jetliner speeds—up to 800 kilometers per hour (about 500 mph)—across entire oceans In deep water, a tsunami may pass beneath a ship as a barely noticeable swell But as the wave reaches the continental shelf near land, it rises—sometimes into a towering wall that swallows entire coastlines

Hence in very deep water, a tsunami will travel at high speeds and travel great transoceanic distances with limited energy loss For example, when the ocean is 20,000 ft (6100 m) deep, unnoticed tsunamis travel about 550 miles per hour (890 km hr), the speed of a jet airplane

Tsunamis have claimed hundreds of thousands of lives and caused hundreds of billions of dollars in damage around the world In deep ocean water, tsunami waves may go unnoticed But as the waves travel closer to the shore, they build in height as the water becomes more shallow
- All About Tsunamis: The Science Behind Tsunamis
In the deep ocean, the typical water depth is around 4000 m, so a tsunami will therefore travel at around 200 m s, or more than 700 km h For tsunamis that are generated by underwater earthquakes, the amplitude (i e wave height) of the tsunami is determined by the amount by which the sea-floor is displaced Similarly, the
- What determines how destructive a tsunami will be near the . . .
For example, in 15 m of water the speed of a tsunami will be only 45 km h However 100 or more kilometers away, another tsunami wave travels in deep water towards the same shore at a much greater speed, and still behind it there is another wave, traveling at even greater speed
- Tsunamis - Woods Hole Oceanographic Institution
How far a tsunami travels depends on a variety of factors Some impact only local shorelines, whereas others can travel around the world The height of the wave on land is determined by a number of factors, including offshore geological features
- Tsunamis - Earth Sci
Normal ocean waves have wavelengths of about 100 meters Tsunamis have much longer wavelengths, usually measured in kilometers and up to 200 kilometers Wave height refers to the distance between the trough of the wave and the crest or peak of the wave
