Oct 2, 2019 · This scale therefore does not saturate. Moment magnitude can match anything the Earth can throw at us. The formula for M w is such that below magnitude 8 it matches M s and below magnitude 6 it matches m b, which is close enough to Richter's old M L. So keep calling it the Richter scale if you like—it's the scale Richter would have made if he ...The moment magnitude scale (MMS) was devised by scientists after the 1960 Chilean earthquake and the 1964 Alaskan earthquake. These great subduction zone earthquakes broke along fault lines that were hundred of kilometers long. The moment magnitude scale in determining an earthquake's magnitude takes in "the entire moment" of the earthquake.The currently accepted method is the moment magnitude scale, which measures the total amount of energy released by the earthquake.

In 1935, the first earthquake magnitude scale (local magnitude: M L) was introduced by Richter for earthquakes in Southern California.After 10 years, Gutenberg extended the local …Like the Richter magnitude, the moment magnitude scale is logarithmic. Both scales are used in tandem because the estimates of magnitude may change after a quake. The Richter scale is used as a quick determination immediately following the quake (and is usually reported in news accounts), and the moment magnitude is calculated days to months later.
