What Causes an Earthquake?

Far beneath us lie the “Tectonic Plates” of the Earth’s crust; slow moving and huge, these 50 mile thick wedges of rock are continuously grinding against each other creating massive energy and heat. Great pressure accumulates here which occasionally leads to energy waves or ‘shock waves’ that travel upwards through the ‘mantle’ of the Earth and are evidenced where we are as ground vibrations. Damage can occur along theses tectonic plate boundaries or along geological fault lines and these are known as ‘zones of weakness’.
