Earth quakes happen across the world each year. The good news is almost all of them are to small to feel.

What causes earth quakes?..

To understand why earthquakes happen it helps to know what going on inside our planet not just what happening on the surface. Also earth quakes are caused by the plates like say the plate slips down and there's a shake in the middle of earth that’s how earth quakes happen.

Our planet is divided into a three main layers: a solid core a liquid magma mantle and a crust, which floats on top. That top crust is made up of individual plates , which are kept inconstant motion by convection currents in the magma.

Plates that collide push rock layers upward which creates mountains. When plates move away from each other or diverge lava comes up from the mantle and cools.

In some places the plates become locked together. Energy build up in the locked plates, which is released in the form of an earthquake when the plates finally give way.
