Tsunami A Wave Of Destruction Made by Martina Camilleri & Meredith Ebejer
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
How can a Tsunami be generated ? A tsunami can be generated when the plate boundaries abruptly deform and vertically displace the overlying water
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.
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.
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”.
