Detailed explanation-1: -The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.
Detailed explanation-2: -Although several scales have been developed over the years, the two commonly used today in the United States are the moment magnitude scale, which measures magnitude (M), or size, and the Modified Mercalli scale, which measures intensity.
Detailed explanation-3: -(1) local magnitude (ML), commonly referred to as “Richter magnitude, ‘’ (2) surface-wave magnitude (Ms), (3) body-wave magnitude (Mb), and (4) moment magnitude (Mw). Scales 1-3 have limited range and applicability and do not satisfactorily measure the size of the largest earthquakes.
Detailed explanation-4: -The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake. On the other hand, a seismograph is an instrument used to detect and record seismic waves.
