7、d been destroyed. Fresh water was taken to the city by train,truck and plane. Slowly, the city began to breathe again.

8、rom falling down. So if your home is in an earthquake area,you should prepare carefully before the earthquake comes. First, make sure you buy a house which is earthquake safe.
