Because the intensities of earthquakes are so large, the Richter scale was developed to provide a “scaled down” measuring system that permits earthquakes to be more easily measured and compared. The Richter scale gives the magnitude R of an earthquake using the formula where I is the intensity of the earthquake and I 0 is a certain minimum intensity used for comparison.
