The Richter-scale, in nature, is logarithmic based on 10. That is, the Earthquake at magnitude 5 is 10 times more powerful than the Earthquake at magnitude 4 and 100 times more than the earthquake at magnitude 3. Today, earthquake magnitude measurement is based on the Moment Magnitude Scale (MMS). MMS measures the movement of rock along the fault. It accurately measures larger earthquakes, which can last for minutes, affect a much larger area, and cause more damage.However, the China Earthquakes Network Center (CENC), which hopes to provide a similar service, measured the same earthquake at a magnitude of 8.1. Advertisement.Each earthquake has a single value on a magnitude scale – the strength right in the body of rock that sprang to a new position or broke. The magnitude scale is logarithmic – an earthquake of magnitude 2 is 30 times as large as one of magnitude 1, and an earthquake of magnitude 5 is 27,000 times larger than one of magnitude 2.Earthquakes are measured on a magnitude scale that is exponential: Each additional unit multiplies the energy released by 32.Moment magnitude, a quantitative measure of an earthquake’s magnitude (or relative size), developed in the 1970s by Hiroo Kanamori and Thomas C. Hanks. ... M 0, measured in dyne-cm (1 dyne-cm = 1 × 10 –7 newton-metre), is essentially the amount of energy released by the earthquake.
