earthquake what makes an earthquake happen? the rock of the earths crust may have a fault, a kind of break in the surface. the blocks which make up the earth move, and sometimes this may cause the sides of the fault to move up and down or lengthways against each other. when one piece of rock starts to rub on another with great force, a lot of energy is used. this energy is changed into vibrations and it is these vibrations that we reef as an earthquake. the vibrations can travel thousands of kilometers and so an earthquake in turkey may be felt in greece. at school as soon as the tremors stop, all students should walk towards the exit and go straight to the school playground or any open space such as a square or a park. they must wait there until the teacher tells them it is safe to go. if you are at home when the earthquake occurs, get immediately under the table in the living room or kitchen. choose the biggest and strongest table you can find. you must not go anywhere near the window and dont go out onto the balcony . once the tremors have stopped, you can come out from under the table but you must leave the building straight away. you should walk down the stairs and should not use the lift - there may be a power cut as a result of the earthquake and you could find yourself trapped inside the lift for hours. if you are in the street when the earthquake takes place, do not stand near buildings, fences or wallsmove away as quickly as possible arid try to find a large open space to wait in. standing under trees could also be dangerous. |
