Earthquake scale magnitude
Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude.The Richter magnitude scale, also known as the local magnitude (M) scale, assigns a number to quantify the amount of seismic energy released by an earthquake.

The moment magnitude scale ( MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake 's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. The severity of an earthquake is measured on a Richter scale. It is logarithmic scale that measures the magnitude of an earthquake. The scale ranges from 1 to 10, with each increase in number indicating a tenfold increase in ground motion.
