Lesson starter: 5 W’s For this section of the lesson you are to pretend that you are a newspaper reporter. You are on route to a big news report and you have been forwarded only one picture. You have time to ask a local authority member 5 questions…..the 5 W’s. Who, What, Where, Why, When.

Title: Environmental Hazard: Tsunami Date: 10/06/2016 Aims: To find out how a tsunami is formed. To look at a case study of a tsunami in detail.
5
Definition What is a tsunami?
6
Definition A Tsunami is a massive wave caused by an earthquake under the sea. It is extremely powerful and it causes lots of destruction. Watch bang goes the theory clip

Why do tsunamis occur? Tsunamis are caused by the movement of the Earth’s crust. When two plates move towards each other at a destructive plate boundary pressure builds up over a long period of time. When this pressure becomes too great the plates will move suddenly and this causes an Earthquake under the water, forcing the crust up quickly. The water above is displaced and this causes a massive wave. Tsunamis come in more than one wave and this is why the flooding is often so terrible.

Japan tsunami - recap There are 4 pieces of poster paper up on the wall. You must visit each one and write down one thing on the page. 1.What damage did the Japan tsunami cause? 2.How do the people of Japan prepare for earthquakes and tsunamis? 3.What was the response to the disaster? 4.How did they try and predict or warn people that the tsunami was coming?

Title: Boxing Day tsunami 2004 http://www.bbc.co.uk/science/earth/natural_ disasters/earthquake#p00hs2py http://www.bbc.co.uk/science/earth/natural_ disasters/earthquake#p00hs2py

Tsunami caught on camera The Boxing day tsunami of 2004 is one of the most terrible natural hazards ever to occur. Over the next two lessons we will gather information on the disaster that will be used for a homework task.
14
Tsunami caught on camera We are going to watch a DvD on the boxing day tsunami. During the DvD you must take notes on: How well was the tsunami predicted? What were the impacts on the people and the landscape? How well were the people prepared to cope with the tsunami? What was the aid response like?

How do people prepare for a tsunami? Think about what you know from studying the Japan tsunami and the boxing day tsunami. Discuss with the people around you and write down your answers.

Preparing for a tsunami In developed counties an early warning system may be in place. This alerts officials that an earthquake has occurred under the sea and that a tsunami will be coming. TV stations will then broadcast this information to the people of the country and often mobile phone will receive a text saying that people should take action. After the boxing day tsunami early warning systems have been put in place in South East Asia
22
Preparing for a tsunami Tsunami wave walls are often common. Large walls are erected along coast lines to stop the tsunami before it reaches the land. However the walls can’t stop the very large wave (such as the case of the Japan tsunami) and this means that they are not always effective.
24
Preparing for a tsunami People can be trained in what to do if a tsunami was to occur. If people had been more prepared for the boxing day tsunami then it would have saved many lives. Military personnel and local services, such as police and rescue services, can also be trained so they can help people in the aftermath of a tsunami.
25
Preparing for a tsunami Even though people can prepare for a tsunami it is an event that can’t be accurately predicted. Much like an Earthquake scientists can do their best to work out when one will occur but there is no guarantee that it will happen.
