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)

HomelearningTo 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 magnitude70,000 deaths400,00 injured5 million homeless$75 million damage200 after shocks700 schools collapsed(On 27th May a 6 magnitude aftershock caused 420,00

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?

PredictPrepare Plan

PREDICTNo 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 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 earthquakesLook at the following picturesWhat 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?ExtraExplain your first 2 choices and your ninth choice

How can we limit earthquake damage?

Why a natural disaster have more of an impact in a LEDC?

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 an earthquake?

Building regulations 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.

Building in earthquake zones

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.

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?
