A tsunami or tidal wave, is sometimes called a seismic sea wave.
It’s a series of waves in the ocean.
It’s often caused by the displacement of a large volume of water.
This displacement of water can be caused by an earthquake, a volcanic eruption or some underwater nuclear device that causes a major shift in water volume.
A landslide, a meteorite impact, or a glacier calving, have the potential to produce a tsunami in ocean waters.
A 9.1-magnitude earthquake hit the coast of Sumatra, Indonesia.
The strong earthquake released a series of gigantic waves from the Indian Ocean, which had a speed similar to that of a jet.
It affected 14 different countries and claimed more or less 230,000 lives.
