5 5 SECTION E CASE STUDY [7] Read the article below about the earthquake in Japan and then answer the questions that follow. Newsflash! Newsflash! Newsflash! Kobe, Japan 17 January 1995 Time: 05:46 Japan Quake Horror A devastating earthquake ripped through central Japan during the early hours of the morning, killing more than people and injuring over people; about people are homeless. Over buildings have been destroyed. Hundreds of people are missing and these figures could rise. Buildings, roads and railway lines collapsed when the earthquake hit the biggest to hit Japan in half a century. The city of Kobe, southwest of Tokyo with a population of 1,5 million, is worst affected. There are terrifying scenes of cars hanging from overhead motorways, derailed trains, highways flipped over, broken glass and rubble and dazed residents wandering about. There are many fires and the smell of gas from broken pipes hangs over the city. In the hours after the first monster earthquake, there were over 400 aftershocks which have prevented rescue workers from helping the injured. Buckled streets, lack of water and electricity are causing problems for residents and emergency workers. The number of people evacuated from wrecked homes, to spend the night in refugee centres set up in schools and gymnasiums, is estimated at Sniffer dogs have been brought in to help find survivors buried under piles of rubble. The killer earthquake measured 7,2 on the Richter Scale. The epicentre of the earthquake was 20 km away from the city of Kobe. The earthquake was very powerful because the cause of the earthquake was shallow, only 20 km beneath the surface. Devastation and rescue after the Kobe earthquake

6 6 1. Name 10 ways in which the earthquake affected the people of Kobe. (10 2=5) 2. What stopped the rescue workers from helping the injured people? (1) 3. What caused this earthquake to be so powerful? (1) SECTION F THINK ABOUT IT [7] 1. What do you think is worse- a volcanic eruption or an earthquake? Give a reason for your answer. (1) 2. An earthquake in Turkey left thousands of people without homes. Read the two suggestions below and answer the questions. "Thousands of people have lost their homes. They cannot sleep on the streets. No one should have to live in a tent or in a big hall with hundreds of others through the cold winter. We must do something to help them as soon as possible. Prefabricated houses can be put up much more quickly than brick buildings with metal support structures. These homes of wood and chipboard are what they need now. We can build stronger buildings later when the emergency is over:' "Quick solutions can lead to problems later. Pre-fabricated houses have weak structures and they are not cheap to build. People will not want to take them down to build stronger homes that will stand up to earthquakes. It is better to give people tents although they are not very warm or comfortable. They will have to stay in these tents while good, strong homes are built for them. This may take a long time, but they must be patient." a. What do you think should have been done to provide homes after the quake? (2) b. What do you think the people who lost their homes would have needed the most? (2) c. Can anyone be blamed for this disaster? Why do you think so? (2)

7 7 SECTION G PARAGRAPH [6] Write a paragraph, including the following facts: # why volcanoes occur # explain what happens underground # explain exactly what takes place as the volcanoes erupt Check each answer carefully! ENJOY THE HOLIDAYS!

11 11 Hundreds of people are missing. Building, roads and railway lines collapsed There are terrifying scenes of cars hanging from overhead motorways, derailed trains, highways flipped over, broken glass and rubble There are many fires and the smell of gas from broken pipes hangs over the city. (10 2=5) 2. There were over 400 aftershocks (1) 3. It was shallow only 25 km beneath the surface (1) SECTION F THINK ABOUT IT.. [7] 1. Any logical answer e.g. an earthquake because it can happen without any warning (1) 2a. any logical answer e.g. put up tents while houses are being built (2) b. food / water / shelter (any 2 logical answers) (2) No, earthquakes cannot be predicted (2) SECTION G PARAGRAPH [6] A volcano is a sign that the Earth s crust is weak. In the Earth s mantle it is so hot that some rocks melt and become a thick flowing substance called magma. Eventually the magma pushes through vents in the Earth s surface. Magma that has erupted is called lava. Lava can come to the surface as a gentle lava flow or a violent explosion. In violent explosions the magma blasts into the air and breaks apart into pieces that range from tiny particles of ash to house-size boulders. These are called volcanic bombs.
