Tsunamis are huge volumes of moving water that become monstrous waves when they hit the coast. What causes them and how do they grow to be so dangerous?
- Tsunamis are massive volumes of moving water.
- Landslides, volcanic eruptions and meteorites can create tsunamis - but they are most commonly caused by undersea earthquakes.
- Displacement of water above fault lines creates ripples which race across the ocean at the speed of a jet plane.
- As tsunamis reach shallow water, faster-moving water catches the front wave, createing a wall of water.
Tsunamis are a force of nature to be reckoned with.
Gigantic waves that decimate the shores they hit.
But what makes them so destructive?
A tsunami is caused by an underwater disturbance.
It's a huge volume of moving water that forms massive waves when it reaches shallow areas.
