This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. However, since the Energy Magnitude and Moment Magnitude measure two different properties of the earthquake, their values are not the same.
