What is a tsunami?
  • Generated from a underwater earthquake
  • Movement of the Earth’s plates causes the earthquake
  • Earthquake displaces water
  • May not be noticed out at sea
  • Waves get higher as the water gets shallower
  • Water recedes when wave is coming
    • A British girl knew this and saved a hotel full of people
  • Happens all the time but can be only a few inches tall
