How do tsunamis travel across the sea?

Answer 1

When tsunamis form in the open ocean they can reach speeds of 500 miles per hour, but they are very small: usually less than three feet high. When they hit shallow water as they approach a shoreline, they slow down, sometimes to less than 50 miles per hour, but build dramatically in weight because of how heavy the water is.

2nd Answereer says: In the deep open sea, tsunamis move at speeds approaching a jet aircraft (500 mph or more). As they approach the shore, they slow down. When a tsunami arrives at the shore, it usually does so as a rapidly rising tide moving at about 70 km/hour (45 mph).

Answer 2

A tsunami(or tidal wave) is a giant wave caused by a seaquake or eruption of sea volcanoes.After these disasters occur,water near the shore recedes as if there is a low tide.Then,the water goes back as a wave at speeds of 800 miles per hour with a height reaching 30 meters.

Another Answer

A tsunami is the landfall byproduct of a large pressure wave propagating through a body of water. An underwater landslide will create a pressure wave as the mass of the landslide moves from one location to another. As the mass is in motion, the pressure of the water in front of the mass is increased while the pressure of the water behind the mass is decreased. The whole body of water this is taking place in reacts by back filling the mass in motion. This causes the propagation of a pressure wave away from the source.

When the wave is traveling through the ocean, the volumn of the whole body of water is so much greater than the relativly small amount of water involved in the wave propagation, that the variation in height at the surface is relativly shallow. The propagating wave can be seen, but it takes a very high point of view with very sensitive height measuring instruments.

Answer 3

Think back to middleschool days, about waves not only just water but even sound waves once they start they spread. In the case of a tsunami usually the ocean floor will move via earthquake.. Causeing a tremendous release in energy that energy spreads like a sound wave, in all directions.. Now what's bad is, you may no notice a

Tsunami until it's too late as you usually wouldn't be able to see it way offshore jn a boat as It only gets taller as the ocean floor gets shallower.
