WebThe surface wave magnitude ( ) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with ... WebJan 1, 2024 · Definition. The magnitude of an earthquake is a number that characterizes the relative size or amount of elastic energy released by such an event (see “Earthquakes, Energy” ). It is usually based on measurement of the maximum ground motion recorded by a seismograph (sometimes for a particular wave type and frequency) and corrected for the ...
