The size and damaging effects or severity of an earthquake are described by measurements of both magnitude and intensity. In seismology (the study of earthquakes), scales of seismic intensity are used to measure or categorize the effects of the earthquake at different sites around its epicenter. Various seismic scales can be used to measure and compare the severity of the seismic event. The amount of elastic energy released by an earthquake is measured on a magnitude scale (see Magnitude Measures) whereas the effects of intensity of ground motion or “shaking” occurring at a given surface point are measured on an intensity scale.
