The Magnitude of an Earthquake is measured on a Richter scale and the Intensity of an earthquake is measured on the Mercalli scale The sudden movement of t ectonic plates leads to an earthquake. Tectonic plates are constantly shifting as they drift around on the viscous, or slowly flowing, mantle layer.
The Richter scale measures the magnitude of an earthquake (how powerful it is). It is measured using a machine called a seismometer which produces a seismograph. A Richter scale is normally numbered 1-10, though there is no upper limit.
Moment magnitude scale. 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. This means that an earthquake of 6 is ten times more powerful than one with a score of 5 and an earthquake of 7 is 100 times more powerful than an earthquake measuring 5 on the Richter Scale.
