The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. 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.

How do you find the magnitude of an earthquake intensity? The Richter scale defines the magnitude of an earthquake to be R=log(IcIn) where Ic is the intensity of the earthquake and In is the intensity of a standard earthquake. Therefore, you can write the difference of two magnitudes as R2−R1=log(I2I1).Intensity data are capable of constraining the magnitude of an event with the same order of uncertainty as individual instrumental magnitude readings (Johnston 1996) and are essential in the study of historical earthquakes.
