Transcript Title: Natural Disaster: Tsunami

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: 16/07/2015
Aims:
To find out how a tsunami is formed.
To look at a case study of a tsunami in detail.
Definition
•What is a tsunami?

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?

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.
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
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.
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.
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.
