What is used to measure the magnitude of an earthquake.
Magnitude is the measure of the energy released by an earthquake. 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.
