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.

What waves cause damage to property?
Tsunamis, storm surges, and rogue waves are examples of waves that can cause damage to property. Tsunamis are large ocean waves typically caused by undersea earthquakes or volcanic eruptions, storm surges are abnormally high tides driven by strong winds during severe storms, and rogue waves are unexpectedly large and powerful waves that can occur even in seemingly calm conditions.
In Greenland how tsunami created without earthquake?
In Greenland, tsunamis can be generated by glacial calving events, where large chunks of ice break off glaciers and fall into the water, displacing a significant amount of water and creating powerful waves. These tsunamis can be locally damaging but are generally smaller in scale compared to tsunamis triggered by earthquakes.
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
What is reinforcement of waves?
Reinforcement of waves, also known as constructive interference, occurs when two waves with the same frequency and in phase align to create a wave with greater amplitude. This phenomenon occurs when the crests and troughs of the waves overlap, resulting in a wave that is stronger than the original waves. Reinforcement of waves is a fundamental concept in wave physics and is essential in understanding phenomena such as standing waves and resonance.
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.
What are the main features of a tsunmi?
Tsunamis are long, high sea waves usually caused by underwater earthquakes, volcanic eruptions, or landslides. They can travel at high speeds across the ocean and cause widespread destruction when they reach land. Tsunamis have long wavelengths and low wave heights in deep water, but their energy allows them to grow larger as they approach the shore.
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.
What are the similarities between rogue waves and tsunamis?
Rogue waves and tsunamis are both large and powerful oceanic phenomena, but they differ in their causes and characteristics. Rogue waves are isolated, exceptionally large waves that can occur in any body of water, often due to constructive interference of smaller waves. Tsunamis, on the other hand, are long-period sea waves typically generated by underwater earthquakes, volcanic eruptions, or landslides. Despite their differences, both rogue waves and tsunamis can pose significant risks to maritime activities and coastal communities due to their destructive potential.

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.
What is it when a combination of waves form a larger wave?
When a combination of waves come together to form a larger wave, it is called interference. Interference can be constructive, where the waves reinforce each other and the resulting wave is stronger, or destructive, where the waves cancel each other out and the resulting wave is weaker.
Where do tidal waves come from?
Tidal waves, also known as tsunamis, are typically caused by underwater earthquakes, volcanic eruptions, or landslides displacing a large volume of water in the ocean. This displacement creates powerful and destructive waves that travel across the ocean at high speeds, eventually reaching and crashing onto shorelines.
Can anyone be affected by Tsunamis?
Well, actually tsunamis can affect only the coastal zones since they come from the sea.
In Greenland how tsunami created without earthquake?

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 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.
