To complete the exam question
By the end of the lesson:
All pupils will be able to evaluate the response of atleast one natural disaster
All pupils will know how to predict and prepare for anearthquake
All pupils will explain how earthquakes managementvaries in different countries
Facts!
8 magnitude
70,000 deaths
400,00 injured
5 million homeless
$75 million damage
200 after shocks
700 schools collapsed
(On 27th May a 6 magnitude aftershock caused 420,00buildings to collapse)
Secondary impacts:
Landslides

PM arrives next day
50 000 solders dig for survivors
Helicopters are used to reach isolated areas
Chinese people donated $1.5 billion

Evaluate the relief effort. Was itgood enough?
YES
NO
Do you think they did enough inSichuan?
It is easy to say ‘NO’ because ………………………
However they had a lot of restrictions, such as……………………………………………………….
This meant that ……………………………………………..
How can we reduce death anddamage during an earthquake?
In pairs, discuss what we can be done before, during andafter an earthquake?
Predict
Prepare
Plan
PREDICT
No one can predict an earthquake but work still continues.
How?
Plan and protect
How can we limit earthquake damage?
GPS satellites can monitor the movement of the earthscrust at plate boundaries
Ground monitoring instruments record what happensbefore, during and after an earthquake
Hazard maps can be produced which can identify the most proneareas
Some animals can sense the initial wave of an earthquake before humans
Plan
How can we plan for an earthquakes
Look at the following pictures
What are they showing you?
How do they work?
Look at the following
What is the difference between the housesin a MEDC and LEDC?
Look at page 21 and 23.
Make a quick sketch of each house
Annotate 2 to 4 features the make it how it is earthquakeproof
Which is more likely to stay standing?
How else can people prepare?
Look at the list of items
In pairs create a diamond 9 activity. Explain it to anotherpair.
Do you agree?

How can we limit earthquake damage?
Why a natural disaster have more of an impact in aLEDC?
LEDC VS MEDC
Lack of education
Lack of planning
Lack of preparation
Which shape of building would be most ‘earthquake proof’?
Explain your answer.
Buildings in earthquake zones
What have you learnt in the ‘Restless earth’topic?
What other measures would make buildings less likely to collapse in anearthquake?
Building regulations in earthquake zones
This is San Francisco in the USA.
San Francisco is near the San Andreas Fault and therefore the city experiencesearthquakes.
This skyscraper has been built to be‘earthquake-proof’.
Its wide base lowers the centre of gravity ofthe building and makes it more stable.
Building in earthquake zones

This is Sky Tower in Auckland, New Zealand.
Sky Tower is the tallest tower (328 metres) in the SouthernHemisphere. It weighs 21 million kilos (20,000 tonnes),which is equivalent to 6,000 elephants!
Auckland is in an earthquake zone and so the tower isconstructed from a high strength, high performanceconcrete.Sky Tower's foundations go down more than 15 metres.
Sky’s the limit!
An earthquake has occurred in this area.
Which area (the town or the forest) will receive the stronger earthquake?
Which area will receive more damage from the earthquake?
