1 Tsunami A Wave Of Destruction Made by Martina Camilleri & Meredith Ebejer

2 What is a Tsunami? A tsunami is a series of waves created when a body of water, such as an ocean is rapidly displaced on a massive scale

3 How can a Tsunami be generated ? A tsunami can be generated when the plate boundaries abruptly deform and vertically displace the overlying water

4 With what can a Tsunami be generated? Earthquakes, mass movements above or below water, volcanic eruptions, landslides, large meteorite impacts & the testing with nuclear weapons at sea all help to generate tsunamis.

5 Tsunamis have been historically referred to as tidal waves because as they approach the land, they take on the characteristics of a violent onrushing tide rather than the sort of cresting waves that are formed by wind action upon the ocean.

6 A Tsunami has a much smaller amplitude (wave height) offshore, and a very long wavelength, Which is why they generally pass unnoticed at sea, forming only a “hump”.
