The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F. Richter (1900-1985) at the California Institute of Technology. This was the magnitude scale used historically by early seismologists.For every 5 steps along the magnitude scale, the brightness will change by exactly 100 times. This means that for each step along the magnitude scale, the brightness of the object changes by a factor of approximately 2.512. For example, a magnitude 1 star is exactly 100 times brighter than a magnitude 6 star.However, these scales "saturate" for earthquakes that are above a certain magnitude (magnitude 8 on the JMA scale); that is, in the case of very large earthquakes, the scales' values change little despite large differences in the earthquakes' energy.
