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. This resulted in an underestimation of the tsunami's height in initial reports.In order to fully grasp the concepts of magnitude and scale, it’s important to see them used in context.
