Scientists now belive that earthquakes are caused by different parts of the earth movingh against each other.African continent(非洲大陆),for example,sits on a large plate of rock,which is moving north and east at a rate of five centimeters(厘米) a year.Europe also sits on a largr rock plate which is moving in a different direction(方向) to the African plate(板块).As the African plate moves slowly northwards,it rubs(摩擦) against the European plate.
Usually,this happen in very small movements that cause very small earthquakes,bring about little damages.But sometimes the tow plates will lock together.When this happens,there is no movement for ten,fifteen or forty years.But when the plates finally move,they move with great force.It is said that lighting(闪电) never strikes twice in the same place,but this is certainly not true for earthquake
