Here is my final answer for What are the safety procedures when a tsunami hits?
The safety procedure of when a tsunami hits is:
1. Watch out for animals behaving oddly – they can detect a tsunami before humans.
2. If you feel the shudder of an earthquake head inland – a tsunami may be coming.
3. Move quickly to higher ground or the top floor or roof of a building.
4. Listen out for official warnings and expect more waves – the next wave may be bigger than the last.
5. Abandon all belongings – there is no time to collect possessions.
6. Don’t count on your car – the roads may be blocked.

Can tsunamis be prevented?
Here is my final answer for Can tsunamis be prevented?
Tsunamis can’t be prevented because they are the result of natural disasters. But there are a few things which can help track and take the power out of a tsunami.
Satellites and tracking buoys can track when a tsunami has been created and can track how fast they are travelling, how long they are, how tall they are, and can track where they are going. These help because they can then warn people that a tsunami is coming.
Tsunami walls are a precaution they some places have to try and stop tsunamis. Tsunami walls are very high and strong walls that when a tsunami hits, the walls can stop the tsunami from coming any further. Usually it places that are known to of have tsunamis hit regularly that have tsunami walls. Even though tsunami walls are quite large, they don’t always work.
Scientists have worked out that mangrove trees could help reduce the force of a tsunami. Mangrove trees can reduce the force of a tsunami because they are so well connected to the ground, they can withstand storms and tsunamis. There are not many mangrove trees around because they are chopped down for building construction.

What happens when a tsunami meets the shore?
Here is my final answer for What happens when a tsunami meets the shore?
Before a tsunami hits the shore the wave is a giant water wall. Then the water will crash down with tremendous power. It then rushes through the land taking with it anything in its path. Houses, trees and people don’t stand a chance as the water rushes through. The original colour of the water is white because of all the whitewash when the waves crash down. Then as soon as the water rushes through the land it changes colour to brown because of all the dirt and debris. Everything in the wave’s path is then picked up to make a floating death river.
Flying debris can kill. Since everything in its path is picked up all the water is filled with wood, dirt and other types of debris. Many of those killed in the Asian tsunami did not drown but were killed by pieces of wood and metal swept along by the wave.
Many people think that a tsunami is one large wave, but it’s not. A tsunami is a series of large waves. Waves can rush towards the shore for several hours. This makes it difficult to rescue people trapped by the water.

Are there areas in the world that have the most tsunamis?
Here is my final answer for Are there areas in the world that have the most tsunamis?
Obviously countries near oceans are at risk but there are certain areas with a greater risk.
The earth’s surface is made up of tectonic plates. A fault line is where two tectonic plates meet and when they do meet they either slide past each other, scrape together or crash head on causing an earthquake.
Fault lines are where earthquakes and volcanic eruptions are most likely to happen and are also areas most affected by tsunamis. A major fault line stretching around the edges of the Pacific Ocean is often called “The Pacific Ring of Fire”. Other fault lines can cause tsunamis in the Indian Ocean and off the coast of Africa.
Places with reefs, bays and sloping beaches are in great risk because if a tsunami waves come in contact with a reef or bay, it can increase the height and power of the tsunami. Places with a bay that goes into a channel are at risk because a narrow channel, make a tsunami very high.

What are the signs of an approaching tsunami?
I added a bit to my last answer
There are many signs of an approaching tsunami to warn you. The first is that you should recognize the original cause of the tsunami. If there is an earthquake in the ocean then straight away you should know that there is a chance a tsunami is coming. It is easy to recognize an earthquake because you can feel the ground shake.
If there is a land volcanic eruption you will be able to see the smoke and feel the ground shake and then you should know that a tsunami is coming. An underwater volcanic eruption is harder to recognize because there is no smoke but you can still feel the ground shake.
If a meteorite lands in the ocean you may be able to recognize it because of it roaring through the sky and the smashing of it into the water.
A very clear sign that something is going to happen is the behaviour of animals. Animals can sense when a tsunami is coming long before humans can. In the Asian tsunami many people saw birds flying inland and making loud noises which was the signal that a tsunami was coming.
The main sign of an approaching tsunami is water rushing away from the shore. When a tsunami is approaching the waves suck all the water away from the shore to gain height and power. The water looks like it is retreating to the horizon. From the time the water is sucked away to the time it hits the shore is a few minutes.

How does a meteorite cause a tsunami?
Here is my final verison of how does a meteorite cause a tsunami?
A meteorite can easily cause a tsunami of it lands in an ocean. If a meteorite lands in the ocean is will first off all turn water around it to steam because of how hot it is and secondly make tsunami waves rush from where the meteorite hit.
A meteorite landing in the ocean acts exactly like a stone being dropped into water. The meteorite hits the water with tremendous force and takes up the place where the water previously was. This then makes the water rush away and produce tsunami waves.
There have been over 200 meteorites that have impacted the Earth in the earth’s history. The biggest one is believed to be that meteorite that hit the earth and had a part in killing the dinosaurs.
Meteorites hitting the earth are extremely dangerous because of how big the tsunamis can be. If a meteorite ten kilometres wide crashed into the sea, it would produce waves up to three kilometres high and would flood nearby continents.
