1 Eray and Shafici’s earthquake investigation

2 How does a earthquake occur An earthquake also known as a tremor is the result of a sudden release of energy in the earth’s crust that creates seismic waves. At the earth’s surface,earthquakes manifest themselves by shaking and sometimes displacing the ground. When a large earthquake ‘s epicentre is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The shaking in earthquakes can also trigger landslides and occasionally volcanic activity An earthquake also known as a tremor is the result of a sudden release of energy in the earth’s crust that creates seismic waves.

3 Where do the most earthquakes occur in the world 80%-90% of earthquakes happen in Japan. It is when there are convergent, divergent or transform plate boundaries. In a convergent plate boundary, two plates will approach each other. The denser plate will then subduct. Friction is produced and the ground shakes, depending on the strength of the quake, causing an earthquake. Shockwaves are radiated out around the area, creating tremors. This is usually the most destructive. 80%-90% of earthquakes happen in Japan. It is when there are convergent, divergent or transform plate boundaries.

4 Do people live in this disaster prone area Yes people live in this disaster prone area because for some people it is their country and they think they belong their then other countries.

5 The impact on people and the environment? Earthquakes and many other natural disasters will cause psychological problems to affected people when they have lost their homes, families and friends. It will also cause casualties when unfortunate people did not have enough time to evacuate from their homes or did not know there was an earthquake. They could be killed by collapsing houses, which will also cost the people a lot of money to rebuild their homes. In developing countries where earthquakes happen, temporary lodging will be provided. However, there might be hygiene problems as many people are crammed into a small space, which may in turn cause viruses to spread. Many properties and infrastructure might be lost and the government will have to fork out a huge sum of money to assist in rebuilding, which may in turn cause a cripple economy. Fires and other secondary effects will also cause more casualties Earthquakes and many other natural disasters will cause psychological problems to affected people when they have lost their homes, families and friends.

6 Can an earthquake be prevented? Preventing earthquakes would cause unimaginable destruction if it were even possible. And it is not possible. Preventing earthquakes would cause unimaginable destruction if it were even possible. And it is not possible. Regulating earthquakes, however, may prove to be beneficial to society without damaging the natural order of Earth. Scientists have discovered that injecting liquid into fault zones can trigger mild earthquake activity. Regulating earthquakes, however, may prove to be beneficial to society without damaging the natural order of Earth. Scientists have discovered that injecting liquid into fault zones can trigger mild earthquake activity. In one study, researchers were able to turn earthquakes on and off like a lamp. Perhaps releasing Earth’s energy regularly in relatively mild tremors would limit the possibility of larger, more destructive quakes. In one study, researchers were able to turn earthquakes on and off like a lamp. Perhaps releasing Earth’s energy regularly in relatively mild tremors would limit the possibility of larger, more destructive quakes. One problem with this plan is that injecting anything into an already unstable area can cause the very earthquakes it is meant to prevent. So the answer is no One problem with this plan is that injecting anything into an already unstable area can cause the very earthquakes it is meant to prevent. So the answer is no

7 How can people work together to restore the damage associated with this disaster? However, we can reduce the impact of earthquakes by a number of strategies. We all live o­n top of geological plates. These plates are being moved by the semi-liquid mantle. These enormous convection currents beneath the surface provide the tremendous forces that move the plates. Some plates move towards each other, and o­n other places the plates are moving away from each other. If you live near the boundaries of the plates the movements can have devastating effects. The mechanism of earthquakes is illustrated Reducing the Effects of an Earthquake There are a number of strategies that can be used to reduce the impact of earthquakes. They all involve being fully prepared for the impact.

8 Find out an emergency group We found that the SES are all over Australia when people are stranded from an disaster in Australia the SES come around and give people medication if they are injured or stranded they also give people shelter if their house are destroyed from an disaster. The SES come with normal cars that says SES on the side of the car they will come when needed We found that the SES are all over Australia when people are stranded from an disaster in Australia the SES come around and give people medication if they are injured or stranded they also give people shelter if their house are destroyed from an disaster.

9 Where did the biggest earthquake happen? We found that the biggest earthquake happened in san Francisco on April 18 at 5:12 in the morning. The impact was that 27,000 to 30,000 were left homeless and 1139 people died because of this earthquake most of the houses were destroyed.

10 Provide a detailed map of one of these examples showing its location in the immediate area This is the map of san Francisco it shows where the earthquakes happened in san Francisco the yellow mark shows that the earthquake was 2.4 the orange mark shows that earthquake was 3.9 and the red mark shows it was 6.00 or more This is the map of san Francisco it shows where the earthquakes happened in san Francisco the yellow mark shows that the earthquake was 2.4 the orange mark shows that earthquake was 3.9 and the red mark shows it was 6.00 or more
