TSUNAMI

Tsunamis are a series of extremely large waves caused by an underwater disturbance such as a volcanic eruption, earthquake, landslide or meteorite impacts. Also it’s a very long wavelength (often hundreds of kilometres long), forming a hump in the ocean.
And it can also, rapidly inundate coastlines, therefore, a tsunami can destroy everything that is in its path, causing damage, injuries, and loss of human life.

A tsunami can have environmental and economical consequences that can take years to reverse.

We can not prevent or predict a tsunami, but we can follow some instructions or system in order to reduce the damage from tsunami. For example, some regions use tsunami warning systems to detect this kind of phenomenon. Another kind of system can be the tsunami walls that Japan has implemented, it consists in a concrete structure up to 13.5 feet high to redirect water from a tsunami.
