What is the difference between the Richter and the Moment Magnitude scales in measuring earthquakes?

Answer 1

Ashley Mcintyre

The Richter scale measures earthquake magnitude based on the amplitude of seismic waves, primarily for small to medium-sized quakes. The Moment Magnitude scale, developed later, provides a more accurate measure for all earthquake sizes by considering seismic moment, fault slip, and area affected, making it more comprehensive and widely used today.
