There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...

Scientists used the Richter Scale for many years to measure earthquakes but now largely follow the “moment magnitude scale,” which USGS says is a more accurate measure of size. June 4 ...

“For this earthquake, the local magnitude was 5.1, but the magnitude we typically use as seismologists is moment magnitude, or MW, based on longer period energy in addition to high frequency ...
