how earthquakes happen

An earthquake is a natural phenomenon that results from underground movement along a fault plane. Shaking and vibration occurs at the surface of the earth as a resulting of the underground movement.
A Tectonics Earthquake is caused by tectonic activity; the tectonic plates shifting suddenly create the power from very small to very large power surges. This earthquake causes a lot of damage or natural disasters on the earth. Strong earthquake vibrations are capable of spreading to all parts of the Earth.

Very interesting indeed, well done :)
