There are a number of natural disasters that can strike across the globe. Two that are

frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great

amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and

cannot happen without them.

The Earth has three main parts. They are the crust, the mantle, and the core. The crust is

the outer layer of the Earth. It is not a single piece of land. Instead,

it

is comprised of a number

of plates. There are a few enormous plates and many smaller ones. These plates essentially rest

upon the mantle, which is fluid. As a result, the plates are in constant - yet slow – motion. The

plates may move away from or towards other plates. In some cases, they collide violently with

the plates adjoining them. The movement of the plates causes tension in the rock. Over a long

time, this tension may build up. When it is released, an earthquake happens.

Tens of thousands of earthquakes happen every year. The vast majority are so small that

only scientific instruments can

perceive

them. Others are powerful enough that people can feel

them, yet they cause little harm or damage. More powerful earthquakes, however, can cause

buildings, bridges, and other structures to collapse. They may additionally injure and kill

thousands of people and might even cause the land to change its appearance.

Since most of the Earth's surface is water, numerous earthquakes happen beneath the

planet's oceans. Underwater earthquakes cause the seafloor to move. This results in the

displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that

forms on the surface and moves in all directions from the place where the earthquake happened.

A tsunami moves extremely quickly and can travel thousands of kilometers. As it approaches

land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in

height. Minutes later, the tsunami arrives. A large tsunami - once more than ten meters in height

- can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill

large numbers of people.
