General Science

  • noun a phenomenon in which the Earth’s crust or the mantle beneath it shakes and the surface of the ground moves because of movement inside the crust along fault lines, often causing damage to buildings


  • Release of energy within the Earth due to chemical phase changes, the relief of stress built up along faults, and possibly other causes. ‘Marsquakes’ and ‘Moonquakes’ have been detected on other planets and space technology – the use of satellites for precise measurements of small movements of the Earth’s crust – is helping to revolutionise the study and possible prediction of earthquakes.
