How did the tsunami affect the landscape?
A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds. Land animals are killed by drowning and sea animals are killed by pollution if dangerous chemicals are washed away into the sea, thus poisoning the marine life.
How does a tsunami change?
As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms. Consequently, as the tsunami’s speed diminishes as it travels into shallower water, its height grows.
What happens when a tsunami hits land?
When a tsunami reaches land, it hits shallower water. A typical tsunami approaching land will slow down to speeds around 30 miles (50 kilometers) per hour, and the wave heights can reach up to 100 feet (30 meters) above sea level. As the wave heights increase during this process, the wavelengths shorten considerably.
What are the prevention of tsunami?
Always advance a Household Emergency Plan and have a Getaway Kit ready with you. Know where the nearest high ground is and how you will reach it. Plan to get as high up or as far inland as you can. Plan your escape route for when you are at home, as well as for when you may be working or holidaying near the coast.
Do tsunamis crash?
They can travel through the ocean with the speed of a jetliner, then rise to heights of 30 feet (9 meters) or more before crashing onto shore and rushing far inland. The awesome power of tsunamis can have deadly consequences. In the past century, tsunamis have killed more than 50,000 people.
What do kids need to know about tsunamis?

How does a tsunami affect the land around it?
When the powerful waves of a tsunami smash the shoreline, they destroy everything in their path. Two mechanisms cause the destruction; the crushing force of a wall of water moving at high speed, and the devastating power of a large amount of water wiping off the land and carrying everything with it.
How big are tsunami waves in the ocean?
Out in the open ocean, tsunami waves are only about one-metre high because the water is deep. However, as the water becomes shallow, the waves slow down and begin to grow.
How long does it take for a tsunami to travel?
Once the water is moved by an earthquake or other event, large waves like ripples spread out from the point where the water first moved. These waves can move quickly and for very long distances. Some tsunamis have been known to travel for thousands of miles across the ocean and travel at speeds of up to 500 miles per hour.
