Find out what a tsunami is and the disastrous consequences they can have.
What causes a tsunami?
A sudden shift in plate movement causes water displacement at the epicentre.
Large waves move along the seabed away from the epicentre.
As the waves move from deep water to shallow water near the coastal area, they increase in height and break.
The effects of tsunamis
The main effect of tsunamis is coastal flooding. The force of such large waves can also destroy coastal property.
