"It measures magnitude based on the size of seismic waves."

Explanation: The Richter (local) magnitude is calculated from the logarithm of the maximum amplitude of seismic waves on a seismograph (with a distance correction). It tends to saturate for very large or distant quakes, so moment magnitude is used to estimate total energy release.
