The amplitude of seismic waves from an earthquake is is measured by a seismometer. From this an estimate can be made of the amount of energy released by an earthquake (this is known as magnitude).

The magnitude of an earthquake is controlled by the amount of energy stored within the deformed rocks of the crust. This is in turn a function of the elastic moduli of the crust, the cross sectional area of the fault rupture zone and the amplitude of the displacement on the fault.
