Quizplus · Accepted Answer

The moment magnitude scale is considered the most accurate as it measures the actual energy released by an earthquake by taking into account the amplitudes of several types of seismic waves, the amount of slip, and the dimensions of the slipped area on the fault. It is also applicable to all sizes of earthquakes and can be used to compare earthquakes of different magnitudes and in different regions. The Richter and surface-wave magnitude scales only measure a specific type of seismic wave and are limited in their usefulness, while the Mercalli scale is based on subjective observations and is not as precise.
