  • The term tsunami has been derived from the Japanese term ‘Tsu’ meaning harbour, and ‘nami’ meaning waves.
  • A tsunami consists of a series of waves which rise a high as 10 metres or more.
  • The speed of the waves is what causes most destruction, as the people do not have time to reach safer places.
  • The tsunami that hit the Indian ocean on December 26th 2004, was recorded as far as Peru and north-eastern Canada.
  • Tsunamis are mostly created by the movement of the sea floor which happens when there is an earthquake beneath the sea floor or near an ocean.
  • The impact of the earthquake causes the sea water to rise and move towards the coast with great force causing immense damage to people and property.
  • The advancement of technology has helped in the early detection of tsunami.
  • Coastal tidal gauges, tsunami detectors and satellite technology enable us to get an early warning of tsunami.
  • As tsunamis are natural disasters and cannot be prevented, the next best thing a state can do is be prepared for the eventuality, to ensure safety for its citizens.
