There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity. Magnitude measures the energy released at the source of the earthquake; Intensity measures the strength of shaking produced by the earthquake at a certain location. The Richter Scale is used for measuring the magnitude of earthquakes. The magnitude value is proportional to the logarithm of the amplitude of the strongest wave during an earthquake. Mercalli scale is used to measure intensity of earthquakes. The intensity of a quake differs greatly from place to place. It depends upon such factors as the distance from the epicenter, the design and quality of construction of local buildings, and the type of surface beneath the buildings.
