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?
