Earthquakes Earthquakes are a violent shaking of the ground They are set off by a sudden snapping or shifting of the giant slabs of rock that make up the Earth’s surface Most are so faint that they are only detectable by the most sensitive equipment But a few are so powerful they can cause devastation destroying cities and killing many people 6
Tsunamis A tsunami is a wave or series of waves set off when an earthquake or volcanic eruption under the sea moves a lot of water The movement spreads out in all directions While under the sea it cannot be seen but once it reaches the coast it sends up a huge wall of water that can cause devastation washing away everything in its path 7
