An earthquake is defined as the 'shaking of the Earths surface caused by rapid movement of the Earths rocky outer layer' (Encarta 1997) . Earthquakes occur when energy stored within the Earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the Earth by earthquake waves.
