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 =
