     On 26th January, the biggest earthquake in India took the lives of 25,000 people. In the morning,

when everybody was enjoying holiday, earthquake began.  It was about 7. 5 0n the Ritcher scale.  

"There is nothing left between the sky and the earth any more. Everything has  been pulled clown," said

one of  the villagers alive. "There is no water, no food and no one has come to help."

     Nobody clied in Pakistan, a country next to India. The city of Lahore was lucky. In   Lahore

American school, where I was studying, all of the students were safe. They were on the field, so most

children didn't feel anything. The earthquake was felt by the teachers that were on the second floor.

However, though Mrs Young was also on the second floor, she didn't feel anything. She didn't know

what happened until a teacher told her about it. Those teachers who were on the other floors had

different feelings. Mr Emond, the maths teacher from Australia, said that when the earthquake started

he thought there was something wrong with him, but then another teacher said that it was an earthquake.

After those words, Mr Emond felt better. Mrs Davis and Mr Frost didn't feel anything either.

     My mother didn't feel anything. She didn't even know that it was an earthquake till she saw a

shaking (moving from side to side) light.  My dad saw the computer shaking and then he looked out

of  the window and saw many people going out.
