Simple News-Earthquake

An earthquake (also known as a quake, tremor, or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves.  

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacing the ground.  Any activity within the earth that creates vibrations can be called an earthquake, whether it's a natural phenomenon or an event caused by humans — something that generates seismic waves.  Earthquakes are caused mostly by the rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments.  Earthquakes send waves through the earth and this means that places many miles from the centre of an earthquake can be affected by these waves.

Crust: outer portion of the earth, hard outer coating of a loaf of bread
