Why do tsunamis grow into larger waves as they come towards land?

Tsunamis are very wide waves while out at sea. As they approach land, the depth of the sea decreases and the base of the front of the wave begins to catch on the sea bed. This slows the base of the wave, but the top is still moving fast. This causes the front of the wave to get steeper and the water to pile up behind the front edge. The waves gets taller/higher/bigger.
When the wave reaches land it is therefore much larger than it was our at sea and because it is such a wide wave, once it reaches land the depth of water behind the front caries on and on. It comes in like a tide rather then as a breaking wave.

Vibrational tremors sent out from an earth quake?
Well there are two P waves and S waves. P waves come first . then S waves come. P waves come from underground and S waves are above ground and move in the shape of an S and they are the ones that collapse buildings
How are floods classified?
Proposals have been put forth to classify tsunamis based on intensity and magnitude. These include the Sieberg Ambraseys and Imamura Iida intensity scales and the Murty and Loomis scale for magnitude.
How are the different types of waves alike?
The different types of seismic waves are alike because all three waves come to the surface at one point. Also because they come after earthquakes.
What waves cause damage to property?
Waves from the ocean which come up with force or depth can cause damage to property. Compressional waves or tsunami waves are an example of these seismic waves.
What are Seismic waves and when do they form?
seismic wave are earthquake waves the types are l - waves, p - waves and s- waves they are recorded by seismograph or also called seismograph they form by explosion's, earthquakes and movement (waves) underground.
What are the main features of a tsunmi?
Tsunamis have large waves that come over land and cause flooding. Plate tectonics cause this.
Do tsuamis always come after a hurricane?
No. Tsunamis have absolutely nothing to do with hurricanes. Tsunamis are generally triggered by undersea earthquakes or landslides. While they are called waves, they are different from normal wind driven waves in that they are much longer, and so carry more water for a given height.
How come tsunamis happen in in few areas and not in the others?
some countries has a big and strong mountain blocking the waves and some doesn't like Hawaii
How does the temperature change if you have an earthquake or tsunami?
The temperature changes because high winds take place and tsunamis are huge waves that come from the ocean which would be cold.
Can anyone be affected by Tsunamis?
Well, actually tsunamis can affect only the coastal zones since they come from the sea.
What are the causes and effects of tsunamis in points?
Tsunamis are caused by shifts in tectonic plates in the middle of the ocean. Once they come ashore, tsunamis can cause millions of dollars in property damage.
Why do ships at sea tend not to notice tsunamis?
Seismic waves moving through the ocean do not form tsunami's until they approach land. At that point the forward motion of the waves pile up on the land and form a series of forward flows that do not have an opportunity to recede due to the following waves. As a result, the waves keep coming on top of the previous waves and come farther inland. Ships at sea do not notice the tsunami until they are over the continental shelf.
What is the difference between a tidal wave and a rogue wave?
A tidal wave (AKA a Tsunami) is caused by an earthquake. It is more of a wall of water and a rise of sea level. when a tidal wave is coming, water will be sucked out from shore rapidly. Tidal waves usually aren't more than 3 feet in open water because in open water it is usually more than 600 feet deep. Rogue Waves can occur in open water and aren't usually caused by earthquakes but just waves that build up. Rogue waves come undetected. Tidal waves have signs. Both are huge in size, up to 100+ ft. Tidal Waves tend to crash on shore while Rogue Waves are violent waves in open water.
Which waves come first P-waves L-waves or S-waves?
P-waves have the highest velocity so arrive first. Please see the related question for further information on the factors affecting seismic wave velocity.
How do tsunamis cause more damage then tidal waves?
A tidal wave is what tsunamis used to be called. The Japanese name has been adopted more recently because of the mistaken impression on the part of the public that a tidal wave was an extremely high tide (see also Neap Tide). A tsunami, unlike a regular wave, does not come in and go back out. The waves have no chance to go out and consequently pile up on top of each other driving far inland.
Where do tsunamis typically form?
tsunamis come from a disturbance in the water like a volcanic erruption which causes the water to draw back creating a huge wave
What is the duration of Here Come the Waves?
The duration of Here Come the Waves is 1.65 hours.
