Detailed explanation-1: -The moment magnitude scale was developed by Thomas C. Hanks (PhD ‘72) of the U.S. Geological Survey and Caltech seismologist Hiroo Kanamori.
Detailed explanation-2: -The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.
Detailed explanation-3: -The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
Detailed explanation-4: -Charles Francis Richter (Hamilton, April 26, 1900-Pasadena, September 30, 1985) was an American physicist and seismologist who developed the first earthquake magnitude scale, a scientific method for measure earthquakes based on the “magnitude", that is, on the energy released during the seismic event.
