What is a tsunami? how is it formed?

Answers:

1. A tsunami, also known as a seaquake is a seism whose epicenter is located at the depths of the sea or ocean (or any a mass of water) producing the agitation of the waters and forming large waves.

2. How is it formed?

After the seism at the depth of the mass of water begins, and if the seism has a vertical component, the movement causes a displacement of the sea bottom and, consequently, it causes the formation giant waves as the water is displaced because of gravity, trying to return to a stable position.

Now, when the tsunami approaches the coast its speed decreases, because the depth decreases, in other words, the water accumulates when braking, increasing the height of the wave.

And, according to the conservation of energy principle, if the speed of the wave decreases, its height increases.
