					Evaluating the responses
  to natural disasters
      Swap books and mark the
         answers out of 4!
Using examples, explain how Volcanic eruptions can be
  predicted. (4)

Suggest two reason why the number of deaths varies
  between earthquakes (4)

Describe one way a region affected by Volcanoes can
  prepare for this hazard (4)

For either an earthquake or a volcanic eruption you have
  studied, describe the immediate responses in
  managing the impacts (4)
              Homelearning
To complete the exam question
     By the end of the lesson:
— All pupils will be able to evaluate the response of at
  least one natural disaster



  All pupils will know how to predict and prepare for an
  earthquake



— All pupils will explain how earthquakes management
  varies 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 420,00
  buildings to collapse)
Secondary impacts:

Landslides

Rescue:

PM arrives next day

50 000 solders dig for survivors

Helicopters are used to reach isolated areas

Chinese people donated $1.5 billion
             International aid
Some countries sent money

The UK gave $ 2 million

Finland sent 8000 6 person tents

Indonesia sent 8 tones of medicine

Rescue teams flu from Russia, Hong Kong, South Korea
  and Singapore
      Evaluate the relief effort. Was it
              good enough?
YES                    NO
 Do you think they did enough in
            Sichuan?
It is easy to say ‘NO’ because ………………………



However they had a lot of restrictions, such as
  ……………………………………………………….



This meant that ……………………………………………..
   How can we reduce death and
   damage during an earthquake?
In pairs, discuss what we can be done before, during and
   after an earthquake?



Predict

Prepare

Plan
                    PREDICT
No one can predict an earthquake but work still continues.



How?
How can we limit earthquake damage?
 Plan and protect
GPS satellites can monitor the movement of the earths
               crust at plate boundaries
Ground monitoring instruments record what happens
      before, during and after an earthquake
Hazard maps can be produced which can identify the most prone
                          areas
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 houses
          in 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 earthquake
  proof


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 another
   pair.


Do you agree?
Extra
Explain your first 2 choices and your ninth choice
How can we limit earthquake damage?
 Plan and protect
Why a natural disaster have more of an impact in a
                     LEDC?



      Lack of education

                                      Lack of planning


                     LEDC VS MEDC




                                    Lack of preparation
Buildings in earthquake zones




  Which shape of building would be most ‘earthquake proof’?
  Explain your answer.
What have you learnt in the ‘Restless earth’
                 topic?
Building regulations in earthquake zones




  What other measures would make buildings less likely to collapse in an
  earthquake?
Building in earthquake zones
This is San Francisco in the USA.

San Francisco is near the San Andreas Fault and therefore the city experiences
earthquakes.




 This skyscraper has been built to be
 ‘earthquake-proof’.
 Its wide base lowers the centre of gravity of
 the building and makes it more stable.
Earthquake aid
Sky’s the limit!
              This is Sky Tower in Auckland, New Zealand.

              Sky Tower is the tallest tower (328 metres) in the Southern
              Hemisphere. 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 is
              constructed from a high strength, high performance
              concrete.

              Sky Tower's foundations go down more than 15 metres.
Epicentre and focus




  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?
