WebCauses: Earthquakes are a sudden release of stored energy. As two plates move past each other they inevitably 'stick'. This allows strain to build up over time and the plates are placed under increasing stress. Earthquakes are generated because of the sudden release of the stress - 'slip-stick behaviour'. WebEarthquakes are the sudden violent shaking of the ground. This happens because the Earth's plates are constantly moving. Sometimes, because of friction, plates try to move …
