The first earthquake happened in the middle of the night on 20th May 2012. I was asleep when suddenly my bed started shaking violently. My family and I ran quickly down the stairs into the street. There was a second earthquake nine days later. The two earthquakes killed seven people, injured another 50 and badly damaged most of the buildings in our town. After the earthquake we lived and slept in the streets for several days. I know that my country is in a seismic area, but some scientists think that one of the causes of the earthquake might be ‘fracking’, the process of drilling down into the earth to find gas. If fracking continues, there might be more earthquakes.

Avalanches are quite common in the Swiss-Austrian Alps but what happened in 1950-51 is called ‘The Winter of Terror’. My grandfather remembers that in three months about 650 avalanches killed more than 265 people and damaged thousands of buildings. Heavy snowfalls, loud noises, vibrations and increases in temperature can cause avalanches. If climate change causes temperatures to rise, there will be more avalanches and there will be more deaths and destruction.

I remember the day before Hurricane Katrina arrived in New Orleans in August 2005. We received an evacuation order from the authorities. 80 per cent of the population left New Orleans. Some people took refuge in the Superdome, a stadium located on high ground, while others waited at home. I didn’t have a car, so I went to the Superdome. The following day the storm arrived and the levees broke. About 80 per cent of the city was submerged under dirty water. Hurricane Katrina killed nearly 2,000 people and thousands of people lost their homes. It happened nine years ago but some areas of the city are still full of abandoned houses. Will New Orleans ever recover from the disaster? There will certainly be more hurricanes. Will my city still be so vulnerable in the future?

Answer 1

1. Luca knew it was an earthquake because the ground started shaking violently

2. One of the main cause of earthquakes is the process of drilling into the earth to find gas.

3. In 1950-51, in Austria, there was about 650 avalanches that killed thousands of people and destroyed many buildings.

4. The main causes of avalanches is the climate changing, the more it changes,the more the temperature rises, the more avalanches will happen.

5. When Hurricane Katrina struck New Orleans, the dam broke and all the water caused a flooding.

6. Claire is worried about the future because, might New Orleans recover from all the damage.
