Hey Readers,
This week our writing task was to write an explanation writing about the article we have chosen. I chose the article called What Causes Tsunami. We needed to explain how/what causes tsunami. There are 2 steps of what cause tsunami and in the conclusion you will also get all the key points from the text. Indonesia is the most common place for earthquakes and tsunamis. In this text you will also find some very interesting facts about earthquakes and tsunamis and even more.

Here is the work
What causes tsunamis ?
What is a tsunami ?
Tsunami is a large tide wave which causes a lot of damage and destruction.
The purpose of this text
The purpose of this text is to tell you how/why what causes a tsunami.
Facts
The name Tsunami is a Japanese word which means harbour wall.
In 2004, a 9.1 magnitude earthquake hit on the coast of Sumatra, Indonesia
which resulted in a 50 m tsunami causing over 200,000 deaths and billions of
dollars worth of damage.
On the 11th of March in 2011, a 9.0 magnitude earthquake caused a powerful
tsunami that hit Japan and killed more than 18,000 people.
1st step of how tsunami is caused
Firstly, a tsunami is seen as moving from the ocean.This is because the wave
is just like the tide that we usually see in the ocean. This part is the first
sign of the tsunami.
2nd step of how tsunami is caused
This large wave can be up to 10x bigger than a normal wave and often hits
the shore and slows down to around 50 km/ph. The back of the wave is still
moving through deeper water, However it is going faster than the front
wave and when it reaches the shore the back wave crashes onto the place. This is why it goes up high.
Conclusion
Tsunamis causes a lot of damage.
Most tsunamis are caused by earthquakes & volcanic eruptions. Some are
caused by landslides and meteorites.
First the wave is seen as moving away from the ocean.
Then it becomes bigger and bigger then slows down to 50 km/ph, the back
wave is moving deeper but faster and finally crashes into the shore. This is
how tsunamis are caused.

Hey Joshvaa Bilal here. I really like your writing about tsunamis and i really did not know that tsunamis can go up to 50 KMPH when it reaches the shore(Even tho i already know). I really wonder how we can get alerts about when a tsunami is going to come and its a interesting topic keep up the good work
