What is Tsunami

A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean, but can occur in large lakes.Owing to the immense volumes of water and the high energy involved, tsunamis can devastate coastal regions.

The principal sources of tsunami are:

• Large submarine or coastal earthquakes, in which there is significant displacement of the seafloor or coast
• Underwater landslides (which may be triggered by an earthquake or volcanic activity)
• Large coastal cliff or lakeside landslides
• Underwater volcanic eruptions

Anatomy of a Tsunami:

A tsunami wave in the open ocean can be more than 100 km across,That’s roughly the length of 1000 American football fields!

As the the tsunami wave reaches the coast it grows in height and slows.  Tsunami wavesn may grow to be many meters high near thecoast and have a tremendous amount of energy.
