A tsunami of biblical proportions could be about to wipe us all out. Scientists have discovered that a 1,000ft wave swept across the Earth some 73,000 years ago.

What is the run up of a tsunami?

The large amount of water that a tsunami pushes onto the shore above the regular sea level is called Run-up, that is the maximum vertical height onshore above sea level reached by a tsunami. Run-up is the more damaging force than the huge tsunami waves as it surges inland and destroys all in it’s path.

Can humans cause a tsunami?

What is effect of tsunami?

Generally tsunamis arrive, not as giant breaking waves, but as a forceful rapid increase in water levels that results in violent flooding. However, when tsunami waves become extremely large in height, they savagely attack coastlines, causing devastating property damage and loss of life.

How does a tsunami start?

Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.

Who is responsible for tsunami?

A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake, an underwater landslide, a volcanic eruption or – very rarely – a large meteorite strike. However, powerful undersea earthquakes are responsible for most tsunamis.
