What are the characteristics of tsunamis?
[1]
They have a short wavelength and high amplitude. They travel at low speed, at around 30 km/h. They decrease in height as they approach land.
They have a long wavelength and low amplitude. They travel at high speeds, sometimes over 700 km/h. Shallow water and the funnelling effect of bays dramatically increases height.
They have a short wavelength and consist of a series of waves. They strike land in quick succession with heights sometimes exceeding 20 metres.
Strong winds whip up large waves which lead to very powerful waves. The funnelling effect of bays creates super-sized waves.
