Earthquakes are the shaking rolling or sudden shock of the earth's surface. It is one of the natural disasters, and when it happens the ground rumbles. Also many people can get hurt.

Eathquakes look like the ground is breathing in and out. The earth will crack and buildings willl fall down, causing a lot of damage to an area. In some earthquakes you can see something falling, something wiggling, and you can see that the floor is rumbling. When the earth shakes, it can be very scary for people and animals, because you can feel a strong shake and see things fall.

Earthquakes can happen by the earth's crust bumping and shaking.They also happen when tectonic plates along the surface of the earth move continuously and slowly pass each other. When the plates squeeze or stretch, huge rocks form at their edges and the rocks shift with great force.
