WebSurface wave magnitude (Ms) is based on the maximum amplitude of the surface wave having a period of 20 + 2 s. It is used for observations near the earthquake epicentre where the surface wave is larger than the body wave. This scale applies to any epicentral distance or type of seismograph. Body wave magnitude (mb) is calculated from the body ... WebJan 1, 2024 · 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 decay of …
