A tsunami is a devastating natural disaster that has put many countries and cities in ruins. A tsunami is a huge wave that is caused by earthquakes or other disturbances. An earthquake is another natural disaster caused by tectonic plates colliding. A natural disaster is an event that is caused by nature and involves a populated area. This information text is about tsunamis and will inform people on a tsunami proof house, predicting a tsunami and preventing a tsunami.
The ‘Tsunami House’ is a waterfront home measuring in at 3140ft2(291.716m2). Is has been nicknamed the ‘Tsunami House’ because it is able to withstand a tsunami and earthquake. This house is on the northern end of Camano Island in Washington. It is not completely tsunami proof but it withstands a 7.8 magnitude earthquake. At the front and back of the house there is glass. If a flood occurs the glass shatters so the water can go straight through. The average magnitude of an earthquake is 5-5.9 so if a tsunami happened to strike the people inside would be mostly safe. This is because of a built in flood room that has certified waterproof things and is completely safe. Although there is no actual list of materials it is made from common materials like wood, concrete and metal. The Cascadia Subduction Zone is roughly 50 miles (80 kilometres) off shore and is a 680 mile (1100 kilometre) stretch of colliding tectonic plates. It is the largest fault line in North America. In 1700 a 9.0 magnitude earthquake happened and caused a 10 metre tsunami to form and travel all the way to Japan.
No. There is no way to prevent a tsunami but thankfully people can prepare for such a devastating natural disaster. Some ways to prepare for a tsunamis are to learn about tsunami chance in an area, plan and practise an evacuation plan, listen to the radio to stay informed and discussing tsunamis within families are all great ways to stay safe in the event of a tsunami. Knowing a communities warning system and disaster plans can possibly safe peoples life and their families’ lives. Tsunami warnings are issued when a tsunami big enough is coming. Warnings help the public prepare for a tsunami. But if a tsunami warning is late it could possibly destroy that country, city or town. Tsunami walls, flood gates and channels are three ways people think of to reduce damage done by tsunamis. In Japan they are not completely safe but they are safer than others because they have built many 14ft (4m) tsunami walls.
Like preventing a tsunami it is impossible to predict one because we cannot predict the earth’s tectonic plates are going to shift and collide any time soon and it is sometimes not certain that after an earthquake there will be a tsunami. Making a warning is only 1 thing preparing is the next. Geoscience Australia is making a warning system to help make tsunami guesses more accurate. With the help of seismometers, seismologists can use mathematics to estimate the height of tsunamis. This method was explained in the Journal of Geophysical Research: Solid Earth. Seismographs, ocean buoys, tide gauges and satellite altimetry are all ways that scientists detect tsunamis. A deep ocean detection buoy is an instrument used by the Bureau of Meteorology. Ocean buoys float on the surface of the ocean. A pressure monitor that goes to the bottom of the ocean and measures difference in deep ocean pressure. Seismographs use signals to find the latitude and longitude of the disturbance. Tide gauges are measuring systems that record how high and how low tides are at specific locations. Satellite altimetry is used for measuring height and in this circumstance wave height.
So in conclusion a tsunami is a huge wave caused by earthquakes or other disturbances. There is a tsunami house that can withstand tsunamis and earthquakes, tsunamis cannot be prevented but people can prepare and they cannot predict a tsunami but they can detect them and make warnings. So in the event of a tsunami by reading this people can be informed and save their lives.

If it were to change so the tectonic plates do not collide and instead one goes underneath the other one it would cause a volcanic eruption instead of a tsunami. It is similar to the system of an earthquake because an earthquake involves two tectonic plates colliding. The order of this system is important because a tsunami cannot happen without an earthquake.
This diagram is shows how tsunamis start.

I’m proud of the tier 3 language I used because it really related to my topic. At that point I hadn’t written up my glossary so I didn’t count it but I will put my glossary on soon. I could’ve used more sequence words and cause and effect language.
