All about Tsunamis

A tsunamis a powerful wave that can destroyed a village . A tsuna-mi is very deep when is about to hit shore. When a tsunami is near land it can to

about 100/ and 31m or it can be more than that and it can ood low lying area. A

tsunami is cause by earth shake.

What cause a Tsunami

A lot of people are scared of a tsunami so here are causes of a tsuna-

mi. An earthquake will shake earth ground and the earthquake will

make li3le waves. Those waves will come altogether so they make a big

wave. Another cause is a volcano because the erupon will shake

the ocean oor also cause waves. Another fact is that meteorites fall in-

to the ocean and can cause large waves. Now here are some eects of

a tsunami. They can ood low lying areas because the large wave can

cover the area by the shore and it can destroy cies and buildings by

hi5ng and by ooding. Sea animals die if they end up on shore from

the waves

How Tsunamis Form

Tsunamis occur in the ocean and they are very fast. At the begin-

ning of a tsunami the rst thing that happens is an earthquake, so

earth ground is shaking. Then the water is moving a lot so it makes li3le

waves come together. While the tsunami is forming the ocean oor is

ge5ng cracks so it is forming a valley is forming. Then as water gets

shallower the bo3om of waves and the top of the waves start to topple

over. Finally as the big reaches the shore all the waves start to push in.

This is the formaon of a tsunami. Thats why I dont like the beach and

because I am scared!

This diagram tells you the formaon

of a tsunami and the 3 basic steps

Similar and Difference of a tsunami

A Tsunami and a ood are the

most common natural disaster that

use water. Here are some similaries.

They can both drown people because

the water get in there houses and

everybody can all drown. They are al-

so natural disasters and they are the

most dangerous water natural disaster. Here are some dierence be-

tween a tsunami and a ood. A tsunami is a big wave that will eventu-

ally reach the shore. Ti is a very fast wave. An earthquake shakes the

ground and makes the ocean oor shake. Now here are some dier-

ence of a ood. It is one of the most common natural disaster. It is a

swelling surging body of water that is rising well above its normal lev-

el. The ood happen fast somemes and someme slow. That is how a

tsunami and oods are the same and how they are not the same.

The Problem and Solutions of a Tsunami

There are many problems but luckily there are soluon

to a tsunami also. One problem is that building may fall from the

forced of the water so they should make the building stronger and

taller. Another problem is people pay a lot of money on there a solu-

on is people can donate goods to help people and animals. Another

problem is that people need to evacuate from their homes so they

dont get hurt. So a soluon is for a tsunami areas to put in warning

system to watch a tsunami and listen to the weather and to warn

people before it reaches shore. Another problem is people who live

in low lying area. Those people should move to a higher ground

right away.

Fun facts about at Tsunamis

A tsunami is a series of ocean waves caused by an underwater earth-

quake, landslide, or volcanic erupon. More rarely, a tsunami can be gen-

erated by a giant meteor impact with the ocean. These waves can reach

heights of over 100 /.

About 80% of tsunamis happen within the Pacic Oceans Ring of

Fire.

The rst wave of a tsunami is usually not the strongest, successive

waves get bigger and stronger.

Tsunamis can travel at speeds of about 500 miles or 805 kilometers an

hour, almost as fast as a jet plane.

The states in the U.S. at greatest risk for tsunamis are Hawaii, Alaska,

Washington, Oregon, and California.

If caught by a tsunami wave, it is be3er not to swim, but rather to grab a

oang object and allow the current to carry you.

Tsunamis retain their energy, meaning they can travel across enre

oceans with limited energy loss.

Sciensts can accurately esmate the me when a tsunami will arrive al-

most anywhere around the world based on calculaons using the depth

of the water, distances from one place to another, and the me that the

earthquake or other event occurred.

Hawaii is always at great risk for a tsunami they get about 1 per year

and a severe one every 7 years. The biggest tsunami that occurred Hawaii

happened in 1946, the coast of Hilo Island was hit with 30 / waves at 500

mph.

Tsunami means harbor wave in Japanese (tsu = harbor + nami =
