What Is More Accurate Than The Richter Scale?
The moment magnitude scale was designed to produce a more accurate accounting of the total energy released by an earthquake, and it calculates the earthquake’s magnitude more accurately than other measures—such as the Richter scale (ML), the body-wave scale (mb), and the surface-wave scale (MS)
Because of the limitations of all three magnitude scales (ML, Mb, and Ms), a new, more uniformly applicable extension of the magnitude scale, known as moment magnitudemoment magnitudeMoment Magnitude (MW) is based on physical properties of the earthquake derived from an analysis of all the waveforms recorded from the shaking. First the seismic moment is computed, and then it is converted to a magnitude designed to be roughly equal to the Richter Scale in the magnitude range where they overlap.https://www.usgs.gov › earthquake-hazards › science › earthq...Earthquake Magnitude, Energy Release, and Shaking Intensity, or Mw, was developed. In particular, for very large earthquakes, moment magnitude gives the most reliable estimate of earthquake size
Explanation: The Mercalli Intensity Scale is a method of measuring earthquake intensity. It measures the damage from earthquakes and the observed effects. Lower numbers indicate intensity likely felt by people and higher numbers indicate damage to structures and buildings

describing how large an earthquake was To describe how large an earthquake was, there is always a qualitative observation approach and a quantitative approach. Using the Mercalli Intensity scale is the qualitative observation approach and the Richter Scale and the Moment Magnitude scale are the quantitative approach
