The moment magnitude scale is the only reliable scale, capable of measuring the largest and the destructive earthquake (that is greater than magnitude 8).Therefore, the greater the magnitude, the more energy is released during the earthquake. Following this logic, this would be a logarithmic scale. Put another way, the increase in magnitude of 1 unit would correspond to the increase in energy release of 30 units. And it is based on this theory that the Richter Scale arises.The Richter scale formula measures and records the movement of the Earth at the epicenter of an earthquake. This number is then used to calculate the energy that has been released. This formula was developed by Charles Richter, in the year 1935.
